Application
For roughing stainless steel materials, particularly full-slot milling.

Features
DIN 6527.
Four cutting edges.
40deg helix.
Ground recess.
AlTiN coating.
HPC geometry.

Advantages
Optimised flute geometry generates tightly rolled swarf discharged through flat chip-breaker recesses while retaining a large stable core.
