Abstract

A grinding tool has diamond superabrasive grains as the abrasive and a bond to retain the abrasive grains. The bond is made of organic polymer or metal and contains as a filler both a solid film-forming lubricant and finely divided diamond superabrasive grains having a grain size smaller than one-third that of the diamond superabrasive grains as the abrasive. The grinding tool of this invention is suitable for grinding a hard cutting material such as cutting tools made of titanium nitride cermet and exhibits outstanding cutting performance and durability.
