Calculations of cutting conditions
Product attributes
Clamping element
more +Straight shank with clamping flat (Weldon) according to DIN 6535 HB.
Tool geometry
more +Helix angle = 45°.
Rake angle = 12°.
End face design
Solid carbide
more +Carbide materials are characterised by high compressive strength, high hardness and therefore high wear resistance, but also limited flexural strength and toughness.
Type N
more +Universal usage. Suitable for materials up to strength 900 MPa.
Feed direction possibility
Oil coolant.
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.
