FAQ

Q: What’s the difference between sintered vs brazed cup wheels?

A: Sintered is more stable and longer-wearing for general grinding. Brazed is usually more aggressive but can wear faster depending on the job.

Q: Which size should I choose?

A: 4.5”–5” for edges/corners and control. 7” for faster coverage on larger areas.

Q: Can it be used on stone (granite/marble)?

A: It can grind some stone, but for best finish and control on stone, choose a cup wheel designed specifically for stone applications.
