Abstract (en)
[origin: US2007257545A1] A cutting tool assembly includes a tool body having a major flare diameter portion disposed adjacent the cutting end of the cutting tool and a puller groove disposed below the major flare diameter portion. A compressible sleeve is disposed about a shank portion of the cutting tool, which is mounted in a tool holder. A washer is fitted about the compressible sleeve, and acts as one of the sides of the puller groove. The location of the puller groove below the major flare diameter portion allows for the cutting tool to be made by cold forming, or the like.
