This wheel has high abrasion resistance because it uses a high-elasticity resin bond made with a special bonding agent. It realizes surface roughness of the same level as final lapping or polishing in a short period of time. By varying the bond content, it can be used to process different materials such as glass, metal, and ceramics. There are two types of bonds available: "RN" bond for better grinding performance and "RP" bond for better surface roughness.
