Smooth Grind, Rugged Performance – Built for Concrete, Block, and Brick Surface Prep

The Bosch DC730S 7-Inch Turbo Diamond Cup Wheel is engineered for high-efficiency grinding and finishing in concrete, masonry, and block applications. Whether you're smoothing rough surfaces, removing coatings, or prepping for overlays, this wheel delivers controlled material removal with minimal vibration.

Built for wet or dry grinding, the wheel features a spin-on 5/8-11 arbor for quick, toolless mounting to compatible angle grinders.
