3 X 18 Inch Silicon Carbide Sanding Belts, 8 Pack

$25.88 ~~$36.45~~ In stock

Our 3x18 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.

James ★★★★★ Oct 22, 2026

These belts worked perfectly for some light detailing on a wood project, the grain cut clean without burning the surface. The pack of eight gives you plenty of spares for different grits, and they hold up well under moderate use.

Olivia ★★★★★ Oct 19, 2026

Been using these on a small woodturning project and the silicon carbide grit stayed sharp way longer than the aluminum oxide belts I had before. They run noticeably cooler against the workpiece, which helped prevent any scorching on the thin pieces I was finishing.

Finally, belts that actually cut cleanly without overheating the workpiece. These silicon carbide ones leave a noticeably finer finish than my old aluminum oxide belts, even with just light pressure.
