Calculations of cutting conditions
Product attributes
Clamping element
more +Straight bore with standard keyway and driving slot according to DIN 138.
Tool geometry
more +Helix angle = 30°.
Rake angle = 10°.
Material HSSE-PM
more +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.
Type HR
more +For roughing operation and materials of medium and higher strength (up to 1200 MPa), surface roughness Ra 6,3 and more.
Feed direction possibility
Coating AlTiN
more +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.
