3 X 30 Inch Silicon Carbide Sanding Belts, 4 Pack

$18.38 ~~$26.25~~ In stock

Our 3x30 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.

William ★★★★★ Sep 13, 2026

I've been burning through belts on my 1x30 grinder for knife handles, so I grabbed these 3x30 silicon carbide ones and the difference in heat is noticeable. Even with light pressure they still cut fast and the finish is way cleaner than what I was getting before. Four belts for the price is a solid

Lily ★★★★★ Sep 12, 2026

These cut so much cooler than the aluminum oxide belts I used before, no burning on cherry even when I leaned into it a bit. Four belts at this price is a steal, and the 3x30 size fits my old belt sander perfectly.

These silicon carbide belts leave a really clean finish on walnut, way less burning than the aluminum oxide ones I used before. I run them on a 3x30 sander with light pressure and the edge stays sharp through a full session. Four in the pack for the price is hard to beat.
