Calculations of cutting conditions
Product attributes
Plain straight shank according to DIN 6535 HA.
Point angle 135°
With coolant holes
Offers similar qualities as TiAlN, but even higher hardness. Substanial temperature stability. Designed for the most demanding applications. It provides excellent result mainly when combined with HSSE-PM steels (ASP 2030). The milling cutters manufactured from this steel are coated with AlTiN as standard.
