Abstract:

A solid cutting blade of the carbide insert type having grooves in its cutting face surfaces formed for creating positive axial and radial rake angles together with properly disposed chip-breaker surfaces when the blade is mounted in a negative rake block-type tool. Multiple grooves are provided so as to give multiple cutting faces on the same blade.
