Deer Bora-7 Purple Ceramic Belt

I was a bit skeptical about trying a non-3M ceramic belt, but these purple ones cut through hardened steel noticeably faster than my old Cubitron II stock. The 90% ceramic grit really holds its edge longer during heavy grinding, and they don't load up as quickly.

I’ve been using these on my surface grinder for high-speed tool steel, and the belt life is easily double what I got from my previous ceramic belts. The consistent cut and minimal loading on tough alloys really impressed me.

These purple belts cut through hardened O1 so much faster than the regular brown ones I used to buy, and they actually last through several knives without loading up.
