Frequently asked questions
Q: What is a flap disc used for?
A: It grinds and finishes in one step — weld blending, deburring, rust and paint removal, and surface finishing on metal and wood.
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: 7" angle grinders with a 7/8" arbor.
Q: Which grit should I choose?
A: Use a coarse grit (40) for heavy stock removal, medium (60–80) for general grinding, and fine (120+) for finishing.
