4x48" Silicon Carbide Sanding Belts

Our 4x48 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.

Victoria ★★★★★

Really nice belts for detail work – the silicon carbide cuts fast but leaves a smooth surface without a ton of pressure. Handled a mix of aluminum and mild steel on my 4x48 sander without loading up too quickly.

James H. ★★★★★

Light pressure is all these need to leave a slick, almost polished finish on steel—they cut fast without loading up. The 4x48 size fits my belt grinder perfectly and the three-pack should last me a good while.

Violet C. ★★★★★

The friable silicon carbide really does make a difference—these belts finish smoother with just light pressure, and the 4x48 size fits my sander perfectly. Three packs mean I’m covered for a few solid shop sessions, and they’ve held up without shredding.
