Finish
TiAlN tip. TiAlN has a microhardness of 3300 HV and thermal stability to about 900 °C (1652 °F), and is used for difficult-to-machine materials such as stainless steel and for higher speeds and feeds.
Cutting speeds and feeds
Cutting speeds (Vc) and feed numbers are given for the D179. Speed (rpm) = Vc × 1000 ÷ (π × Ø); treat these as starting values.
