 Diamond grinding discs are used for grinding and polishing of building materials and natural stone. 
Cup Wheels are ideal for grinding and shaping natural stone products, especially for concrete and hard materials. They are also widely used for profiling edges, smoothing  cuts, and smoothing rough surfaces for lamination. Designed for dry or wet use, they provide heavy material removal and are optimum wheels for any grinding, shaping or beveling work that needs to be done. These cup wheels feature cooling flute holes in the steel core; 8 holes for the 4" cups.
