Abstract

An abrasive article includes a bonded abrasive body having abrasive particles contained within a bond material. The bonded abrasive body includes an abrasive particle-to-bond material interfacial hardness of at least about 13 GPa. The bonded abrasive body is configured to grind a workpiece comprising metal at a speed of less than about 60 m/s.
