Tired of tear-out on the back of your cuts? These zero-clearance inserts are the fix for your Delta table saw. You get a 3-pack, so you can have one for your standard blade, one for a dado stack, and a spare. They're designed to fit Delta 36-725, 36-725T2, and 5000 series contractor-style table saws. A 'zero-clearance' insert has a slot cut exactly to the width of your saw blade, which provides support right up to the blade teeth. This prevents thin workpiece edges from tearing or splintering as they exit the cut, giving you cleaner, safer cuts in plywood, veneer, and melamine. Made by ZEROSERT, they're brand new and a direct replacement for your factory insert. An inexpensive upgrade that makes a huge difference in cut quality. Just install and make the initial cut to create the perfect slot for your blade.
