Table Saw Zero Clearance Inserts

A zero clearance insert is a throat plate with a kerf cut exactly to the blade width, leaving no gap around the blade. This supports the wood fibers right up to the cut, reducing bottom-face tear-out and keeping thin offcuts from falling into the saw.

Yes, in most cases. Each insert is cut for a specific blade width and tilt angle. Using a plate with replaceable inserts — like the SawStop ZCI with 3-piece insert pack — makes this practical because only the insert needs replacement, not the entire plate.

Yes. Infinity Tools offers zero clearance throat plates and replacement inserts specifically designed for SawStop cabinet saws and contractor saws. Check individual product pages for model-specific fitment.

The Betterly TruCut system is a universal zero clearance insert designed to be trimmed and fitted to a wide range of table saw models. It is an alternative for saws that do not have a manufacturer-specific insert available.

With the blade fully lowered and the insert installed flat in the throat plate opening, clamp the insert in place. Slowly raise the spinning blade through the insert material to cut a kerf that exactly matches the blade width and position.

Replace a zero clearance insert when the kerf opening becomes wide enough that it no longer provides adequate support for the workpiece at the cut edge. A 3-pack of replacement inserts lets you have fresh inserts on hand for different setups.

Yes. Shopwood or MDF can be cut to fit the throat plate opening and used as a DIY zero clearance insert. However, manufactured inserts made from phenolic or aluminum-backed plastic are flatter and more durable than most shop-made versions.

A zero clearance insert works best alongside a quality blade and proper setup. Browse table saw blades and the full table saw accessories collection for complementary products.
