Product attributes

Clamping element

Clamping element

more +
Straight bore with standard keyway and driving slot according to DIN 138.
Tool geometry

Tool geometry

more +
Helix angle = 30°. Rake angle = 12°.
Material HSSE-PM

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 NR

Type NR

more +
For roughing operation and materials of lower and medium strength (up to 700 MPa), surface roughness Ra 12,5 and more.

Coating AlTiN

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.
