This multi-flute Tough Mill is designed for stable peripheral finish milling. Its high flute count and 45° helix support smooth cutting action, reduced deflection, and productive finishing passes when the setup and work material are suitable. The square-end profile is suited to side milling, shoulders, pockets, and flat-bottom features.
The AlTiN coating supports heat and wear resistance in demanding milling applications.
