Bosch DC410HD 4" Double Row Segmented Diamond Cup Wheel are specially designed with high-quality industrial diamonds for premium lifetime and surface finish.

The 5/8 In.-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.
