A: Type 27 is flat for surface and edge work on flat areas; Type 29 is conical for more aggressive stock removal and better contact on edges and contours.
Q: What grinder do these fit?
A: Angle grinders that accept a 5" disc with a 7/8" arbor.
Q: Why ceramic grain?
A: Ceramic self-sharpens for fast, cool cutting and longer life, ideal for stainless steel and hard alloys.
