Frequently asked questions

Q: What is the difference between Type 27 and Type 29 flap discs?
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, rated to at least 12,200 RPM.
Q: Why ceramic grain?
A: Ceramic self-sharpens for fast, cool cutting and longer life, ideal for stainless steel and hard alloys.
