Bosch Diamond Cup Wheels are specially designed with high-quality industrial diamonds for premium lifetime and surface finish. These cup wheels are standard market height and can be used for a wide range of applications in dry concrete and masonry grinding – from aggressive material removal, leveling, waterproofing preparation and more. The diamond matrix is specially formulated for dry-concrete-grinding applications. As the diamond matrix wears down, new diamond grit is exposed to provide long life. The 5/8"-11 threaded arbor allows for a tool-free, spin-on attachment to the grinder. Each wheel features a precision-balanced steel body, which reduces wobble and vibration for control over material removal and a smoother finish. The double-row segmented cup wheels are ideal for fast material removal in concrete grinding . The turbo-row cup wheels provide a smoother finish for floors, walls, ceilings and more.
