摘要

The cutter blade (1) has blade surfaces (8,9) and chamfer (7) which are arranged at first side (11) of cutter edge (6). The first side of cutter edge is perpendicularly extended with respect to rotation axis (X-X). A taper is provided at second side of the cutter edge so that thickness of cutter edge (D) is decreased.
