Tool for cutting fitting recesses and thread

摘要

The inner flank cutting edge (4) is almost parallel to milling axis (5). The outer flank cutting edge (6) and an inner flank cutting edge (4a) are inclined at approx. 30 deg. to the milling axis. The thread tapping edges (8) adjacent to the outer flank cutting edges are approx. parallel to milling axis, as are the precut teeth and the finishing edge. The inner flank cutting edges have the same undercut and are divided at the front edge into two front cutting edges by a simultaneously formed hollow throat. The tool (3) cutting edge supporting part is an integral component.
