Diameter: 2.5 inch, Thickness: 0.1 inch. Please measure your saws recess to ensure proper fit
They fit Delta, Rockwell, some Jet, Ridgid, Grizzly, and other imports.
Make sure your insert recess has the locating pin on the side, not on the rear..IMPORTANT INSTALLATION NOTE: First make sure the lip of the hole is free from dirt. If a table alignment pin,is not tight or missing,often the blade mounting slot will close up some over time which reduces the insert hole diameter slightly. I tap a flat head screw driver into the blade installation slot a bit to wedge it open. That should spread the insert hole enough for it to fit
