Abstract

A cutting matrix has a top surface, a first cavity for tightening the cutting matrix in a cutting tool, and a cutting edge for cutting by stock removal. A second tightening cavity is arranged coaxially with respect to the first cavity. The first cavity is deeper than the second, and both are below the upper surface of the cutting matrix.
