Metal Bond Diamond Grinding wheel is synthetic diamond that is used in non-ferrous application, has superior hardness, high fracture strength and uniformed properties, as well as excellent wear resistance and high thermal conductivity. Designed specifically for Concrete floor restoration professional, for quick removal of any materials, bonds Hard, Medium, or Soft available for kinds of concrete. The hard segment is ideal for removing heavy coating. The bar segment is extremely aggressive leaving and deep to medium scratch pattern. The double segments remove adhesives, coating and lippage, taking the floor from coarsely structured surface to pre-polishing.    Screening Emery Emery is the raw material for hot press forming, with high density, large particles, strong hardness, stable cutting, and wide range of objects    Groove design, reduced impedance slip Double chip chute design, fast chip evacuation, reduced resistance slip, lower noise, long-lasting durability, higher efficiency, dry grinding without burning chips  Diamond material Selected high-quality diamond materials, high density, high hardness, sharp wear-resistant and long service life
