The resin bond diamond wheel is used for grinding PCB drill bits, and is available in both a straight type and flaring cup type. This super abrasive, combined with a resin, allows the wheel to meet requirements for both wet and dry grinding.

Benefits

High removal rate: it can improve productivity to create more parts in a specific period of time.
Good shape retention: it is not easy to deform when grinding.
Good surface finish.
High abrasion resistance.
