3 X 79 Inch Silicon Carbide Sanding Belts, 4 Pack

$41.61 ~~$56.23~~ In stock

Our 3x79 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.

Zoe ★★★★★ Oct 22, 2026

I've been using these for flattening out heat-treated steel handles and they cut so cleanly with barely any pressure. The silicon carbide grit really does stay cooler than the zirconia belts I used before, and the 4-pack means I'm not constantly reordering.

The grit on these belts stays sharp through several projects, and the silicon carbide really does cut cooler than regular aluminum oxide. I've been using them for final passes on walnut, and the finish comes out glass-smooth with almost no burning.

Ran these on my drum sander for some heat-sensitive pieces and the friable grit kept the surface cool throughout the process. The 3x79 size fit my machine perfectly with no need for trimming. Solid value for a four-pack at this quality level.
