These diamond cup wheels feature venting holes for faster, rough dry or water-cooling grinding and provide exceptional wheel life. They are ideal for surface preparation, edge blending, smooth shaping and finishing, as well as de-burring, and tilt wall finishing of masonry surfaces. Premium Rowed Cup Wheels are used with angle grinders and floor grinding machines for cutting concrete and field stones. Dry and wet use.
