Calculations of cutting conditions
Product attributes
Straight bore with standard keyway and driving slot according to DIN 138.
Helix angle = 30°.
Rake angle = 12°.
Extra high performance high speed steel produced by powder metallurgy. It has a homogeneous structure resulting in higher dimension stability and longer tool life. It is applicable for machining of materials with very high strength and materials hard to machine, such as Titanium and its alloys. The milling cutters made from this material are delivered with AlTiN coating as a standard.
Universal usage. Suitable for materials up to strength 900 MPa.
Feed direction possibility
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.
