Our 3 1/2x15 1/2 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.

Emma J. ★★★★★

These silicon carbide belts leave a noticeably finer scratch pattern than the aluminum oxide ones I was using, especially on end grain. I run them with light pressure for finishing and they still hold up through a whole batch of cutting boards.

Ellie ★★★★★

I use these on my 1x30 belt sander for shaping knife handles and the silicon carbide cuts way faster than the aluminum oxide belts I had before. They hold up well with light pressure and don't burn the wood like duller belts do. Four in a pack for this price is a solid deal.

William U. ★★★★★

These belts cut cleanly on my heat-sensitive steel without scorching the metal, and the friable grit stays sharp through several passes. The 3 1/2 by 15 1/2 size fits my sander perfectly, and I'm glad I grabbed the four-pack for the price.
