Toolroom Grinding Wheels for Hardened Steel

Flared Cup
Made with boron nitride, second in hardness to diamond, these wheels are highly wear resistant and easily cut difficult-to-grind steel parts. While they’re not as hard as diamond, they dissipate heat better.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
