6 X 89 Inch Silicon Carbide Sanding Belts, 2 Pack

$26.71 ~~$40.47~~ In stock

Our 6x89 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.

Richard O. ★★★★★ Oct 22, 2026

I was a bit skeptical about how well these would hold up on my handheld sander, but the friable silicon carbide grit actually stays sharp through several uses. The extra length of the 6x89 size gives me a nice full bed on the platen for even wear.

Aurora Y. ★★★★★ Oct 20, 2026

The friable grit cuts cleanly on heat-sensitive metal without leaving burn marks, which is exactly what I needed for light finishing passes. The 6x89 size fits my sander perfectly and the two-pack means I’m not scrambling for a fresh belt mid-job.

I've been using these for finish work on some heat-sensitive resin pieces and the friable grit really does stay cool. The 6x89 size fits my sander perfectly and the silicon carbide cuts cleanly without clogging up.
