Milling cutter from the Humm Hard series.
A six-flute end mill for machining hardened steel. It is characterized by stability and long service life in the case of hardness from 48 to 65 HRC. Its chip flute design provides improved milling deviation, and the applied PVD coating increases resistance and resistance to adhesion and abrasion, which additionally increases the tool’s service life.
