$25.43 ~~$36.86~~ In stock

4x36” Industrial Grade Silicon Carbide Sanding Belts

Our industrial grade silicon carbide belts are the perfect choice for fine finishing with lighter pressure. Silicon carbide is extremely sharp and friable, making it ideal for heat sensitive applications but not as long lasting as other abrasive materials. Its unique characteristics make silicon carbide a great choice for paint removal, sanding between coats, knife scale finishing, lapidary, or any application requiring consistent scratch patterns. Wet or dry applications. Hand built in the USA.

Thomas Z. ★★★★★ Oct 22, 2026

The silicon carbide grit stayed aggressive through an entire batch of oak boards, way longer than the aluminum oxide belts I used to buy. They flex well around the 4x36 platen without cracking at the seams.

Benjamin ★★★★★ Oct 21, 2026

I’ve been using these on my woodturner for final passes, and the silicon carbide cuts cleanly without loading up with dust like cheaper belts. The 3‑pack means I can swap grits quickly between coats of finish.

Finally, a sanding belt that actually lasts through a whole project without glazing over. The silicon carbide grit stays sharp and cuts cleanly even when I use lighter pressure on my 4x36 sander.
