"Learn why resharpening PCD woodworking tools with ceramic diamond grinding wheels is crucial for optimal performance. Discover how using 400# and 800# wheels prevents tool chipping, improves surface quality, and extends tool life."
Moresuperhard recommends ceramic bond diamond grinding wheels for the rough grinding of the cylindrical surface of the diamond layer on PDC cutters. These wheels demonstrate excellent efficiency and cost-effectiveness compared to traditional resin bond wheels.
