A zero clearance insert is a replacement throat plate machined so the opening hugs your saw blade with almost no gap. That gap is what lets wood fibers fall away as the blade exits, so shrinking it to match the kerf supports the workpiece to the last tooth and keeps the back of the cut clean. It also stops small offcuts dropping into the cabinet where the blade lives.
That is the whole promise of the best zero clearance inserts for table saws: a cleaner back edge on plywood, veneer and hardwood, better dust flow, and a saw that no longer chews up narrow strips. The catch is compatibility. Inserts are not universal. They are cut for a specific saw opening, a specific screw pattern and often a specific blade width, and buying the wrong one is the single most common regret we saw in buyer reviews.
So compatibility comes first in this guide. Every entry below names the saw models it fits, and the buying guide has a four-step measurement routine you can run in about ten minutes to confirm a fit before you order. If you have not settled on a saw yet, our picks for the best table saws for woodworking and the best cabinet table saws for fine woodworking cover the machines these inserts are cut for.
We compared ten inserts across the brands that dominate the accessory market, weighing the material each one is built from, whether the plate is a finished insert or a blank you cut yourself, whether a riving knife or splitter still clears once it is installed, and how it holds up over years of service. Ten models is the right number here, not for padding but because inserts are strictly saw-specific and the useful shortlist has to span DeWalt, Ridgid, Delta, SKIL, Bosch and the older contractor saws that no factory serves anymore.

Leecraft DW-2 Phenolic for…
- High-density phenolic laminate
- Bonded-melamine low-friction surface
- Leveling and lateral adjustment screws
- Precut blade bottom pocket
Two things separate these three from the rest. The Bosch assembly carries the deepest review history of any insert we examined, which means its failure modes are well documented and its fit is predictable on the saws it covers. The ZEROSERT pack solves the problem most Delta owners actually have, which is a plate thin enough to work and stable enough to keep flat, plus a spare so a bad cut does not end your afternoon. The Leecraft DW-2 is the one to buy if you want the stiffest material in the group and own one of the two DeWalt saws it fits.

Read the fitment lines before anything else. Four of these ten are blanks you cut to your own blade, which means the buyer also needs a table saw or a friend with one and a tolerance for a ten-minute job. The rest arrive ready to install.
1. Bosch TS1005 Zero Clearance Insert Assembly for 4100 and 4000 Series Table Saws
Bosch TS1005 Zero Clearance Insert Assembly for Table Saws Red 4100, 4000
Fits Bosch 4100XC and 4000 series
Reduces kerf clearance to blade thickness
13.75 x 3.75 x 0.5 inch, 4 ounces
1 year manufacturer warranty
Pros
- Reduces kerf clearance to the thickness of the blade for accurate 90 degree cuts
- Cuts down tear-out at the cut line
- Quick drop-in throat plate replacement
- Weighs only 4 ounces
- Backed by a 1 year manufacturer warranty and a 30 day return window
Cons
- Plastic body is more flexible than phenolic or MDF alternatives
- Fit must be confirmed against your specific Bosch 4100 or 4000 series opening
- Sold as an assembly rather than a flat plate
This is the insert with the deepest buyer history in the group, and that matters more than any spec line. When 800-plus owners describe the same part, the patterns are trustworthy: the tear-out improvement is real and consistent, and the drop-in install is genuinely a drop-in for the Bosch 4100XC and the 4000-series cabinets it was cut for.
What the part does is straightforward. It brings the table surface right up to the thickness of the blade so the cut is supported on both sides, which is why the 90-degree accuracy holds up on trim and on narrow strips where a wider gap would let the piece twist. At 4 ounces it adds no meaningful weight to the saw.
The tradeoff is material. This is a plastic assembly rather than phenolic laminate or CNC-machined MDF, and a minority of owners report it giving slightly under load compared with the stiffer plates. If you rip a lot of thick hardwood and put real side pressure on the workpiece, you will feel that difference. If you are crosscutting plywood and sheet goods, the chip-out improvement carries most of the value.
It is manufactured in Taiwan and carries a 1 year manufacturer warranty with a 30 day money-back window. Buyers consistently describe it as reducing kerf clearance to the thickness of the blade, which is the entire point of the part.
Who this insert suits
This suits the Bosch owner who wants the biggest improvement per minute of effort. If you own a 4100XC or a 4000-series cabinet saw and you cut plywood, laminate or narrow trim, this is the shortest path from a torn back edge to a clean one. It is also the option with the least guesswork, because the fit is widely reported and the part is unchanged across owners.
It also suits anyone who is nervous about drilling into a saw casting. There is no tapping required, unlike the OEM SKIL plate covered later in this guide.
Who should skip it
Skip it if you own a different Bosch generation, or if your saw is not a Bosch at all. Inserts are model-specific and this one has no cross-brand claims. It is also the wrong choice for a shop that runs dado work regularly, since the plate is cut for a single blade kerf and not for a stacked dado set.
And if you already own one of the phenolic plates further down this list, a stiffer material will serve you better long term. The Bosch part wins on convenience and evidence, not on rigidity.
2. ZEROSERT 3-Pack with Dado Plate for Delta 36-725 and 36-5000 Table Saws
ZEROSERT Zero Clearance Table Saw Inserts w/DADO – Delta Compatible – 36-725, 36-725T2, 36-5152, 36-5000, 36-5000T2 Table Saws (3-Pack)
Commercial-grade CNC-machined MDF
Covers Delta 36-725, 36-5152, 36-5000
Three identical plates plus a dado plate
Leveling access holes
Pros
- Three plates machined identically so swapping one for another needs no readjustment
- Access holes let you adjust leveling screws without pulling the plate
- Covers five Delta models across the 36-725 and 36-5000 families
- Includes a dado plate for groove work
- Owners report three-year-old plates still in daily service
Cons
- Usually needs light sanding to reach a friction fit in the opening
- Commercial-grade MDF is vulnerable to edge chipping if dropped on concrete
- Occasional units arrive slightly warped
Delta owners have a specific complaint, and this pack is aimed straight at it. The factory plate on the 36-725 and 36-5000 families is thin stamped steel, and experienced woodworkers consistently rate it below a solid machinable plate for chip-out. This is commercial-grade MDF, CNC machined in the USA, and the three plates are cut to the same dimensions so they are interchangeable.
That interchangeability is the feature owners mention most. Set the leveling screws once and you can swap to another plate for a different cut without touching an adjustment. A forum poster who has compared several plate types on the same Delta saw described these as better than both the thin factory steel and a homemade plywood insert, which is a fairly strong endorsement for a part at this level.
The third plate is wider and carries a dado slot, so you can cut grooves without hunting for a second solution. One owner noted the dado plate’s cutout is shaped around a riving knife, which means it earns its keep for dado work on a saw that has one, though it is wasted space on a pure dado stack.
Durability reports are encouraging. Buyers cite three-year-old plates still in daily service, and the MDF holds its flatness far better than the birch plywood scraps and hardwood blanks that show up in most shopmade attempts. One user on r/craftsman113 described a shopmade plywood insert as making a huge difference, and that is the same instinct this product industrialises.
Who this insert suits
This suits the Delta 36-725, 36-725T2, 36-5152, 36-5000 and 36-5000T2 owner who cuts sheet goods and wants a spare plate. The access holes for the leveling screws save you from removing the plate every time you want to make it flush, which is a small thing that matters on a saw you use daily.
It also suits anyone tired of a warped homemade plate. Warping is the single most common complaint in insert threads, and it is almost always a material problem rather than a machining problem. MDF resists it better than cross-grain hardwood, and you can seal the surface if your shop is humid.
Who should skip it
Skip it if your Delta is a contractor model outside those five numbers, or if you plan to leave a full factory splitter installed. The plate is cut for a saw whose splitter is lowered or removed, and forcing hardware around it is how inserts get cracked.
Expect to sand it lightly on first fit. A friction fit is the intent, not a defect, and a few owners report the need to shave a corner to get it flat. If you want zero fitting work, the Leecraft phenolic plates are a better bet.
3. Leecraft DW-2 Phenolic Insert for DeWalt DW744 and DW746
Leecraft DW-2 Zero-Clearance Table Saw Insert for DeWalt Model DW744 and DW746
High-density phenolic laminate
Bonded-melamine low-friction surface
Measures 13-5/8 by 3-3/4 inches
Leveling and lateral adjustment screws
Pros
- Phenolic laminate stays rigid and flat for years
- Low-friction melamine face lets work slide instead of stick
- Reducing noise
- dust
- chip-out and splintering
- Includes leveling and lateral adjustment screws plus a rear anti-lift pin and a precut blade bottom pocket
Cons
- Fitment is limited to the DeWalt DW744 and DW746
- Arrives as a blank you cut to your own blade
- A plate that is cut wrong cannot be returned
Phenolic laminate is the stiffest material in this roundup, and stiffness is what keeps a plate flat after a year of use. Leecraft’s high-density phenolic with a bonded-melamine face is the construction most owners single out when they describe why their cut quality improved. It measures 13-5/8 by 3-3/4 inches and weighs in as a solid piece rather than a hollow pressing.
The low-friction face is the part people notice during a cut. Work slides across the plate instead of catching, which is what makes a clean back edge on veneer and figured wood possible. Owners report a marked reduction in chip-out compared with the DeWalt stock throat plate, along with less noise and less dust.
The hardware is thorough. You get leveling screws for height, lateral adjustment screws for side-to-side position, a rear anti-lift pin so the trailing edge cannot curl up, and a precut pocket at the bottom for the blade when it is fully retracted or tilted for a bevel. That pocket is a small detail that prevents the plate from fouling on a blade that is not cutting anything.
One thing to plan for: this arrives as a blank. You pass your own blade through to cut the kerf slot, which takes a few minutes and gives you a slot matched to your blade rather than to a nominal width. Cut it once, carefully, because a plate cut for the wrong kerf will not work for a second blade.
Who this insert suits
This suits the DeWalt DW744 and DW746 owner who wants the best material money solves and does not mind ten minutes with a table saw. Those two saws are contractor machines that get moved and dragged, and a rigid phenolic plate tolerates that handling far better than a thin plastic pressing.
It is also the right pick if you crosscut hardwood frequently. The phenolic body does not flex under side load, so a 90-degree cut on a solid board stays square.
Who should skip it
Skip it if you own a DWE7491, a DWE7490 or a DWE7485. This plate is cut for two specific models, and the DWE7485 and DCS7485 in particular use a different insert with a different riving-knife clearance. There are dedicated DeWalt options later in this guide for those saws.
Skip it if you have never cut a kerf slot by hand. It is a straightforward job on a table saw, but the plate is expensive to replace if you cut it wrong, and the material is a blank rather than a finished insert.
4. CNC Custom Designs 4-Pack of Inserts for DeWalt 744 Through 7491
Cncdesigns Zero Clearance Inserts (4-Pack) for DeWalt 744, 745, 746, 7480, 7491 & 7491RS, 7490 Table Saws
Four MDF inserts at 0.25 inch thick
Covers 744, 745, 746, 7480, 7490, 7491 and 7491RS
Low-friction painted top surface
Four leveling screws included
Pros
- Highest average rating in the group at 4.7
- Four plates let you dedicate one per blade or kerf width
- Snug accurate fit on most DeWalt models with little or no sanding
- Includes four leveling screws for fine height adjustment
- Painted top surface is low friction and easy to spot against cast iron
Cons
- Not intended for use with a riving knife in place
- Included wood screws may need their tips ground down
- Pointed leveling screws can cut into the surface if over-adjusted
- Base material is soft chip-prone MDF rather than phenolic
The DWE7491 is the most common portable table saw sold, so it is unsurprising that the highest-rated insert in this roundup covers it. This pack holds four quarter-inch MDF plates, cut for the DeWalt 744, 745, 746, 7480, 7490, 7491 and 7491RS. Owners of the 7491 and 7491RS report a near-perfect fit with no sanding, and a 4.7 average across 266 reviews is the strongest rating signal we found.
Kerf width varies by blade, and if you run a thin-kerf rip blade and a thick-kerf crosscut blade, one slot cannot serve both well. Keeping a dedicated plate per blade means each one keeps its own slot and its own leveling setting, which the maker supports with four included leveling screws.
Two cautions sit in the lower-starred reviews and both are worth reading before you order. First, this pack is not intended for use with a riving knife in place. If your 7491 has the factory riving knife, you cut your own clearance slot or you use it with the knife lowered. Second, the included wood screws sometimes arrive with tips that need grinding down, and the counterbore orientation can run opposite to the printed instructions on some plates.
The MDF is quarter inch thick and painted a low-friction yellow on top, which is a useful visual cue: you can see at a glance whether the plate sits flush or slightly proud. The maker also accounts for the table fabric on one side of the opening, which is a small detail that stops the plate rocking.
One more thing to verify before you click through: this is not the insert for the DWE7485 or DCS7485. Those saws use a different plate, and a dedicated version appears later in this guide.
Who this insert suits
This suits the DWE7491, 7490 and 7491RS owner who runs more than one blade, or who wants a spare so a chipped plate is a swap rather than an afternoon. It is also the pick for a DeWalt owner whose shop humidity is moderate, since sealed MDF is a reasonable compromise and a phenolic plate costs more.
Sellers of this style of part often answer fit questions directly and include a handwritten note, and that matters when you are choosing between two nearly identical plates.
Who should skip it
Skip it if you rely on the riving knife every cut. Cutting your own clearance is doable but adds real work, and a purpose-made plate with a molded slot is the cleaner path. The DWE7485 pack further down is built for exactly that case.
Also skip it if you run a dado regularly, since none of these four plates is cut for a wide stack, and skip it if you drop tools on your table. MDF edges chip.
5. Peachtree UHMW Blank Insert for the Delta Uni-Saw
UHMW Tablesaw Zero Clearance for Delta Uni-Saw 13-3/8″x 3-3/4″ x 1/2″
Solid UHMW slab at half inch thick
Measures 13-3/8 by 3-3/4 inches
You cut the kerf slot
Fits Delta Uni-Saw 10 inch
Pros
- Entry cost sits well below the phenolic and CNC-machined plates
- Tight snug fit that stays put once installed
- Works as both a kerf plate and a dado plate
- Levels up easily with the included hardware
- Substantially reduces chip-out on sheet goods
Cons
- No dado relief cut on the back so you need a smaller blade to start the kerf slot
- UHMW can bend and will not spring fully flat once flexed
- Loose height set screws and no side-to-side adjustment
- May need light trimming with a handplane to fit
This is the value end of the list, and it is a genuinely capable part. It is a half-inch slab of UHMW, ultra-high-molecular-weight polyethylene, measuring 13-3/8 by 3-3/4 inches and weighing 1.3 pounds. That thickness is roughly double the quarter-inch MDF plates, and a heavy slab is why it resists deflection under the workpiece even though the material itself is soft.
It is a blank, so you pass the blade through to cut the kerf. The result is a slot that is exactly your blade’s width rather than a nominal one, and owners report a very tight fit that stays put in the saw once installed. Several describe roughly a quarter hour from unboxing to first cut, which is quick.
The Delta Uni-Saw is the target machine, a 10-inch contractor saw where the factory opening is large enough to be genuinely hazardous on small work. Owners report a clear reduction in chip-out, and the plate doubles as a dado plate once you have cut it wide.
Material matters more here than anywhere else in the roundup, because UHMW is the softest plate material listed. It is also the toughest, which is why a half-inch slab of it outlasts thinner plates on the same saw. Expect the finish to be less crisp than a phenolic face but expect the chip-out control to be close.
Who this insert suits
This suits a Delta Uni-Saw owner on a budget who is comfortable doing one cutting job. If you want to spend less than any phenolic or CNC-machined option and still close the gap, this is the plate. It is also a good choice for a secondary saw that gets used intermittently.
It suits anyone who owns a starter blade of smaller diameter, because a relief cut on the back lets you plunge the kerf from below without a big blade. Without that cut you need to start the slot with a smaller blade first.
Who should skip it
Skip it if you want a plate that never needs adjusting. The height set screws are reported as loose and there are no side-to-side adjustment screws, so getting it perfectly flat is more work than on a phenolic plate with a full hardware set. UHMW also flexes permanently, and a plate that has been bowed will not return on its own.
It will not serve a 45-degree miter without modification, and there is no thumb hole, so removal is awkward. If you are fussy about finish quality, the smoother phenolic faces will look better on the exit side.
6. Leecraft RG-1 Phenolic Insert for the Ridgid TS3650
Leecraft RG-1 Zero Clearance Table Saw Insert for Ridgid TS3650 Table Saw
High-density phenolic laminate
14 by 3.8 by 1 inch, 1.22 pounds
Leveling plus side and end screws
Precut blade bottom pocket
Pros
- 4.7 average with an 84 percent five-star share
- Phenolic body is rigid
- stays flat and looks factory-like
- Friction side and end screws lock the plate down with no wobble
- Finger hole makes removal and swapping fast
- Owners report hundreds of cuts with no visible chip-out on panel goods and solid walnut
Cons
- Not sized for the Ridgid 2400 jobsite saw without light sanding
- Adjusting the screws is fiddly and rewards a well-handled driver
- Phenolic builds pitch on the blade that needs periodic cleaning
- Rear tab alone will not hold the plate flat without a hold-down screw
The Ridgid TS3650 is a cast-iron benchtop saw with a big reputation for build quality, and the RG-1 matches it. Same phenolic laminate and bonded-melamine face as the Leecraft DeWalt plates, cut to 14 by 3.8 by 1 inch and weighing 1.22 pounds. It carries a 4.7 average with an 84 percent five-star share, and owners describe it as outperforming every homemade plate they have tried.
Fitment is the easiest part of this review. Owners of the TS3650 say the plate sits flush out of the box, with the friction side and end screws holding it down with no wobble once it is leveled. The finger hole is a small upgrade that makes swapping plates fast, and the instructions are described as clear and to the point.
The precut blade bottom pocket is worth understanding. When you lower the blade below the table or tilt it for a bevel, the teeth would otherwise hit the plate. This pocket gives them somewhere to go, so the plate works for tilted cuts and for jobs where the blade is not engaged at all.
On a saw with this much mass, the plate is not what determines accuracy, but it is what stops the back edge from tearing. Owners running solid walnut report clean edges across panel goods and hardwood alike, which is the result you are paying the phenolic premium for.
Who this insert suits
This suits a TS3650 owner who wants a factory-looking plate that stays flat and quiet. If you cut walnut, cabinet panel and laminate in the same week, a rigid phenolic face and a low-friction surface are the combination that keeps the back edge clean across all three.
It is also the pick for anyone who has tried a shopmade insert and watched it warp. On r/woodworking, a thread on a homemade Ridgid insert described a fully adjustable plate sealed in gloss poly to keep moisture out, and a LumberJocks discussion noted that hardwood inserts tend to warp, cup or sag over time. Phenolic sidesteps that whole category of problem.
Who should skip it
Skip it if you own the smaller Ridgid 2400 jobsite saw. Owners report it is not sized for that opening without light sanding, so the friction fit you get on the TS3650 does not carry over. For a 2400, the UHMW blank in this roundup is the better-matched part.
Also be prepared for the screw adjustment to be a little awkward, and keep a scrap handy for wiping phenolic pitch off the blade every so often. The rear safety tab alone will not hold the plate flat on a rough cut, so add a hold-down screw if your work is heavy.
7. Peachtree UHMW Blank for Craftsman and Older Ridgid 10-Inch Saws
UHMW Tablesaw Zero Clearance for Craftsman/Ridgid 14″x 3-3/4″ x 3/16″
UHMW blank at 3/16 inch thick
14 by 3-3/4 inches
Fits TS-2412, TS-2424 and TS-2400
Covers 1988 and newer belt-drive models
Pros
- Covers older Ridgid and Craftsman saws that have no factory insert
- Setup takes roughly 15 minutes from install to first cut
- Large finger hole helps with removal and leveling
- Well machined and square once fitted
Cons
- Thin UHMW can arrive bowed and the crown is hard to flatten
- Skirts are flimsy so four set screws will not stop warp
- The included roll-pin latch is reported as ineffective
- Included set screws may not reach flush height and can fall out
Some of the most common table saws in older shops never got a factory zero clearance insert, and for those machines this blank is often the only off-the-shelf answer. It fits the Ridgid TS-2412, TS-2424 and TS-2400, plus many 1988-and-newer 10-inch belt-drive models including vintage Sears and Craftsman contractor saws.
That legacy coverage is genuinely useful. SawdustZone makes the same point in a different context, noting that a plate fitting one Grizzly cabinet saw also fits a Whirlpool cabinet of the same generation because the openings match. Cross-brand interchangeability is real, but only when the table opening and screw pattern line up, which is why measuring your own saw is still the first step.
At three-sixteenth inch, this is the thinnest plate in the roundup. That keeps it easy to trim and shape, and it slots into shallow castings without relief work, but it also means the material can arrive slightly bowed. Owners with clean, accurate results out of 1990s Sears and Craftsman contractor saws report a big improvement over the oversized factory opening.
Who this insert suits
This suits the owner of a legacy 10-inch belt-drive saw with a gap too large to work around. If your machine predates factory inserts entirely, or if your factory insert is stamped steel that has racked, this blank closes the opening and supports small parts. A 15-minute setup is a fair trade for that.
It is also a reasonable second plate for a saw that already has a serviceable insert, since a spare blank in a drawer is cheap insurance against a chipped or worn plate.
Who should skip it
Skip it if you need a plate that stays flat under load. This is the one with the most hardware complaints in the group: bowed out-of-the-box units, flimsy skirts that let the plate move during a cut, an ineffective roll-pin latch, and included set screws that may not reach flush height on their own. Several owners replaced the latch hardware or upgraded to longer set screws to make it behave.
If your saw is a modern machine with a phenolic or CNC-machined option, the rigidity difference is obvious. Buy this for the saw nobody else made parts for.
8. SKIL STZ6307 OEM Insert for the TS6307-00
SKIL Zero Clearance Table Saw Insert Plate for SKIL Table Saw TS6307-00 – STZ6307, Multicolor
Official SKIL part number STZ6307
Fits the TS6307-00 10 inch saw
17.72 by 4.72 by 0.39 inch
Quick-release plate change
Pros
- The only OEM-brand insert in the roundup with a 1-year limited warranty
- Best sellers rank of any option covered here
- Effectively solves narrow-strip cutting and keeps small cutoffs from reaching the cabinet
- Fixes the tear-out of the stock plastic plate
- Installation takes about 15 minutes for most owners
Cons
- Requires drilling and tapping into the saw aluminum table casting
- Supplied self-tapping screws are reported as poor
- Thin plastic flexes under light pressure and can let narrow stock dip toward the blade
- Hard to get perfectly flush with one side staying proud
This is the official SKIL part, number STZ6307, made for the TS6307-00. It is also the best-selling insert in the accessory category among everything we examined, and it does the two things a 10-inch jobsite saw owner most needs: it fixes the tear-out from the stock plastic plate and it stops narrow strips from dropping through into the cabinet.
At 4.1 stars it is the lowest-rated product in this roundup, and the reviews explain exactly why. The install demands drilling and tapping into the saw’s aluminum table casting for hold-down screws, and owners report the supplied self-tapping M4x0.7 screws breaking or seating poorly. Using a real tap is the fix almost everyone settles on.
There is also a hardware mismatch. The listing photographs show a quick-release button, while the plate that arrives uses a turn latch. The quick plate change is a genuine advantage of this design, so expect a moment of confusion on the box.
Because the plate is moulded to a single saw rather than cut from a blank, there is no kerf-fitting step at all. That is the trade against the OEM price and the tapping requirement: nothing to cut, nothing to sand, but something to drill.
Who this insert suits
This suits a SKIL TS6307-00 owner who wants the manufacturer part and a warranty behind it, and who is comfortable drilling a hole into a casting once. Fifteen minutes of work is all it takes for most owners, and the payoff is immediate on trim, molding and small parts.
It is a good choice for a jobsite saw used by one person, because the plate is sized to the saw and needs no cross-brand guesswork.
Who should skip it
Skip it if you like your castings untouched. Tapping into aluminum is reversible with a thread tap and patience, but a sheared screw head in a table is a real risk with the included fasteners, and a marred table bothers a lot of owners.
Also skip it if you rip thin stock under pressure. This is a thin plastic plate, and several owners report it flexing enough to let narrow material dip toward the blade. For a 10-inch jobsite saw, the stiffer UHMW blank is the safer choice.
9. Leecraft DW-3 Dado Insert for DeWalt Table Saws
Leecraft DW-3 Zero-Clearance Dado Table Saw Insert for Dewalt Saws (Colors May Vary)
Dado-width phenolic blank
Measures 13-9/16 by 3-3/4 by 29/64 inch
Covers seven DeWalt models
Instructions included
Pros
- Widest DeWalt model coverage of any Leecraft plate listed at seven models
- Phenolic body is rigid
- flat and low friction
- You cut the slot with a dado blade or a standard blade to match your stack
- Reduces chip-out and splintering on dado work
- 4.6 average across more than 340 reviews with 76 percent five-star
Cons
- Factory splitter or guard is incompatible and must be lowered or removed
- Supersized for standard kerf work since this is a dado-width plate
- Sold as a blank that you cut to match your blade or dado stack
- Colors vary between units
Grooves are where a kerf-width plate stops helping. A dado is a flat-bottomed cut made by a stacked set of blades, and the combined width of that stack is far wider than a single blade kerf, so the stock plate leaves a gap that ruins the fit of a cabinet side or a shelf. This Leecraft plate is cut wide, at 13-9/16 by 3-3/4 by 29/64 inch, and you open the slot to match your own stack.
Same phenolic construction as the standard-kerf Leecraft plates, so the material notes carry straight over: rigid, stays flat, low-friction face, and a marked reduction in chip-out. The 4.6 average across more than 340 reviews with 76 percent five-star puts it level with the DW-2 as the best-rated phenolic in the group.
Model coverage is the standout. It fits the DeWalt DW744, DW745, DW746, DWE7480, DWE7490X, DWE7491RS and DWE7499GD, which is seven machines. That is the widest DeWalt coverage of any Leecraft plate we found, and it is worth checking your model number against this list before anything else, because the manufacturer also prints a measure-before-ordering warning on the plate itself.
Widening the slot is a one-time job and the payoff is permanent for anyone who runs grooves regularly. Flat-bottomed dado cuts leave the workpiece supported across the whole width of the cut, which is what makes a shelf sit flush against a cabinet side without a scribe.
Who this insert suits
This suits the cabinetmaker and the furniture builder. If you cut dados for shelves, drawer runners or backs, this is the plate that makes the groove bottoms flat and the joints close properly. It also suits anyone who wants one insert material across several DeWalt saws in the same shop.
For repeat dado work, the standard-kerf phenolic plate in this roundup is the right companion, since a dado plate will not make a clean single-blade cut.
Who should skip it
Skip it if you do not cut grooves. The plate is deliberately wider than a standard kerf, so installing it for ordinary crosscut work is a waste of the opening it provides. And skip it if you plan to run the factory splitter or guard, which is incompatible and must be lowered or removed.
It is a blank, so budget time to cut the slot with a dado blade or a standard blade. If you have never done that job, the narrower phenolic plate is the gentler place to learn it.
10. CNC Custom Designs 4-Pack for the DeWalt DWE7485 with Riving Knife Slot
Cncdesigns Zero Clearance Inserts (4-Pack) for DeWalt DWE7485 with riving Knife Slot
Four blank MDF inserts for DWE7485 and DWE7485WS
Molded riving-knife clearance slot
Offset leveling screws included
Works with blades or dado blades
Pros
- The only option covered here with a molded riving-knife slot so the knife can stay in place
- Four plates allow dedicated inserts for 90
- 45 and 22.5 degree cuts plus a spare
- Fits the DWE7485 and DWE7485WS tightly with no sanding or just a touch on one corner
- Improves thin-cut and crosscut length accuracy over the stock insert
- Seller verifies the saw model and includes direct contact details
Cons
- Included leveling screws are slightly too long and are often swapped for grub screws
- The MDF blank can bow up slightly on the thin side after the blade plunge
- Some units bow on one side and need repeated shaving
- Threaded bosses for the leveling screws would be a better design
The DWE7485 is a different animal from the other portable DeWalt saws, because its riving knife sits behind the blade and passes through the throat plate opening on every cut. An insert without clearance for that knife either blocks it or gets cut by it, which is why so many plates sold for DeWalt saws carry a warning about riving knives. This pack has the clearance slot molded into all four plates.
That makes it the only option in this roundup that lets a DWE7485 owner keep the factory riving knife in place with a zero clearance insert. That is a safety feature, not a convenience one, and it is the reason to buy this pack even though a phenolic alternative exists for other DeWalt models.
The four blanks are a genuinely clever allocation. Each of the four blanks can go to a dedicated slot for 90-degree crosscuts, 45-degree bevels and 22.5-degree miter work, with the fourth kept as a spare. Buyers report the fit is tight on both the DWE7485 and the DWE7485WS, frequently with no sanding at all.
Who this insert suits
This suits the DWE7485 and DWE7485WS owner who will not give up the riving knife, which is most of them. Owners report a clear improvement in thin-cut accuracy and crosscut length accuracy over the stock plate, and that the seller confirms your saw number before sending, which removes the most common failure mode with aftermarket parts.
It also suits anyone who miter a lot, since a separate plate per angle means you are not re-cutting one plate between 90 and 45 degree work.
Who should skip it
Skip it if you own a 7491 or 7490. This pack is cut for the DWE7485 family only, and the four-pack for those saws is a different part. Verifying the number printed on your saw is the single most important step before ordering.
Be aware of two build complaints: the included leveling screws are slightly too long, and several owners substitute grub screws threaded into the MDF instead. Some units also bow on one side after the kerf plunge and need repeated shaving to go flat. Budget an evening rather than an afternoon.
How to Choose a Zero Clearance Insert for Your Saw
Compatibility decides everything. No insert in this roundup fits more than a handful of related models, and the wrong plate will not drop in, will sit proud of the table, or will block a riving knife. Start by measuring rather than guessing.
How to measure your throat plate before you order
Step one: find the model number. It is usually on a badge on the cabinet, under the table, or on a sticker near the motor housing. That string of numbers and letters is the only reliable way to match a plate, and it takes thirty seconds.
Step two: measure the length and width of the opening in the table, not the throat plate itself. Measure the recess the plate drops into, from the cast-iron edge to cast-iron edge. For example, a plate listed at 13-3/4 by 3-1/2 inches should correspond to an opening of the same footprint, and a plate at 14 by 3-3/4 inches will not drop into a smaller recess.
Step three: measure the depth of the recess. Plates range from three-sixteenth inch on the thinnest blanks to one inch on the thickest phenolic bodies. If your recess is shallow, a thick plate will sit above the table and create a step that catches your workpiece.
Step four: check the screw and hardware pattern. Note the location of any existing screw holes, any riving knife or splitter clearance slot, and whether the left side of the opening is bare casting or covered with table fabric. A design that accounts for the fabric will not rock. If the numbers do not match what the seller lists, do not order.
Insert materials compared
Phenolic laminate is the stiffest and most stable option. It stays flat through years of humidity swings, resists pitch and glue, and has a smooth low-friction face. It is the best choice for a heavy-use benchtop saw.
Commercial-grade MDF is the best balance. It machines beautifully, holds a screw, and is dimensionally far steadier than a shopmade plywood plate, but it chips at the edges and can swell in a humid shop. Seal the surface with a finish coat if your garage is damp.
UHMW is soft but tough and easy to shape. It is forgiving of a saw that has no matching aftermarket part, and a three-sixteenth inch blank can be trimmed to fit, but it flexes permanently and will not spring back.
Hardwood is what most people reach for first and what forum threads warn against. A thread on r/BeginnerWoodWorking described hardwood inserts warping, cupping or sagging over time, which is why gloss poly or another seal coat is the standard finishing step on a shopmade plate.
What to do when the insert is too tight
This is the most common complaint in insert reviews, and it is a fixable problem. Do not force the plate. Lay it flat on a work surface, mark the high spots with a pencil, and sand those areas with medium-grit paper on a flat block, checking the fit in the saw after every few passes.
Work the whole perimeter rather than one corner, because a plate that enters at one corner and binds at the other will rack the casting. Test-fit, sand, test-fit, and stop when it slides in with firm hand pressure. A friction fit that needs no tools is the target, and buyers who describe press-fit plates as a feature are describing exactly this end state.
If a plate drops in but rocks, the fix is at the leveling screws, not the perimeter. Back them off evenly and re-level against the table surface with a straightedge.
How to tell when an insert is worn out
Check the slot width first. Every cut through the plate removes a little material, and over time a slot that was snug becomes visibly wider, which is the normal reason a correct-fit insert eventually feels loose.
Check the height. Run a straightedge across the table and across the plate. A step up or down means the plate has cupped or a leveling screw has loosened, and a step is the deal-breaker that catches workpieces mid-cut.
Check the surface. A plate scored with blade tracks, chipped at the edge, or delaminated at the melamine face is finished. And check the fit under pressure: if a small offcut can still drop toward the blade, the gap is back and the plate has done its useful work.
How to make your own zero clearance insert in six steps
For saws with no aftermarket part, making your own is a well-trodden path. Sawmill Creek Woodworking Community users describe building their own plates when nothing manufactured exists, and video results on this topic are dominated by shopmade builds.
Step one: remove the stock throat plate and take a full-size paper or cardboard template of the opening, including the screw hole positions and any riving knife clearance.
Step two: transfer the template to material. Half-inch MDF is the most forgiving choice for a first build because it machines easily and holds a screw. Avoid cross-grain hardwood, which is the material forum posters most often regret.
Step three: cut the plate slightly oversize, then work it down to fit. Pass your blade through repeatedly rather than measuring a nominal kerf, and open the slot a hair wider than the blade so the cut is supported without pinching.
Step four: drill and tap holes for leveling screws, or use threaded inserts if the material is thin. Countersink them so screw heads do not stand proud of the surface.
Step five: seal the plate. Two or three coats of gloss poly or a hardwax oil keep moisture out of MDF and birch ply and make the surface easier for the workpiece to slide across.
Step six: fit and level. Set the plate flush with the table using a straightedge, then make test cuts in scrap and check for a clean back edge before you trust it on plywood.
One safety note that comes up constantly in forum threads: confirm what your saw does with a riving knife, an MJ splitter, or a kerf keeper before you install anything. If the plate has no clearance cut for it, the knife must be lowered or removed, and you need to know that before the plate is in place.
Frequently Asked Questions
What is the benefit of a zero clearance table saw insert?
A zero clearance insert replaces your saw’s stock throat plate with one machined so the opening hugs the blade with almost no gap. That gap is what lets wood fibers fall away as the blade exits, so closing it supports the workpiece to the last tooth, prevents tear-out on the back of the cut, keeps small offcuts from dropping into the cabinet, and improves dust flow. It is one of the cheapest upgrades a table saw can get.
Why don’t table saws come with zero clearance inserts?
Most table saws ship with a thin pressed steel or molded plastic throat plate because it is cheap, light, and easy to shape during assembly. A solid plate in phenolic or MDF costs more, weighs more, and has to be machined to fit each casting precisely. The result is a standard opening wide enough to support the blade but loose enough to let tear-out happen and small parts drop through.
Are zero clearance inserts universal?
No. Inserts are model-specific, cut for a particular saw opening, screw pattern and often a particular blade width. Some cover one saw exactly, some cover a family of related models such as the Delta 36-725 and 36-5000 series, and some blanks are cut by the buyer to their own blade. There are occasional cross-brand matches when two cabinets share the same opening, which is why measuring your own throat plate before ordering is essential.
How do I know which zero clearance insert fits my saw?
Find the model number on a badge on the cabinet or under the table, then measure the length, width and depth of the opening in the cast-iron top. Compare those three numbers against the plate dimensions listed by the seller, and check whether your saw uses a riving knife, an MJ splitter, or a factory guard that needs clearance in the plate. If the dimensions do not match exactly, do not order.
Does zero clearance tape work?
Zero clearance tape is a thin strip applied inside the existing opening to narrow the gap. It reduces tear-out somewhat and costs almost nothing, but it does not eliminate the gap the way a solid insert does, it can peel or shift over time, and it adds nothing to small-part support. For a saw you use on sheet goods regularly, a proper plate is the better investment.
What should I do if the insert is too tight to drop in?
Do not force it. Lay the plate flat, mark the high spots with a pencil, and sand them evenly around the whole perimeter with medium-grit paper on a flat block. Test-fit in the saw after every few passes and stop when the plate enters with firm hand pressure. A friction fit is the intended end state, and owners consistently report a light sanding session on first install as normal rather than a defect.
Final Verdict on Zero Clearance Inserts
The best zero clearance inserts for table saws are the ones cut for your exact machine, and among these ten the Bosch TS1005 assembly is the safest all-round buy, the ZEROSERT three-pack is the strongest value for Delta owners, and the Leecraft phenolic plates are the best material for anyone who wants a plate that stays flat for years. Measure your opening before you order, confirm whether a riving knife needs clearance, and expect a short evening of fitting. It is the cheapest visible improvement a table saw can get in 2026.
