陶瓷皮帶

The cryolite grinding aid really does its job—the belts run noticeably cooler, and I’ve been through twice the steel stock without any heat discoloration. The heavy cloth backing also holds up better than the flimsy ones I’ve used before.

I was skeptical about the 25% longer wear claim, but after sanding metal for a full afternoon these belts outlasted my old ones easily. The cryolite coating really does keep the heat down during heavy use.

The cryolite grinding aid is a real lifesaver—it noticeably keeps the heat down on longer passes. Running them on steel, I’m getting closer to that 25% extra life than with the zirconia belts I’d used before. Backing feels sturdy too, no premature fraying at the edges.
