Calculations of cutting conditions
Product attributes
Plain straight shank according to DIN 6535 HA.
Normal profile of flute, normal core, point angle 118°. Drills made of HSS Co mildly strenghtened core, point angle 130°.

Point angle 135°

Right helix
Carbide materials are characterised by high compressive strength, high hardness and therefore high wear resistance, but also limited flexural strength and toughness.

Company norm
Conical lip relief, DIN 1412 form N.

Drilling depth 8xD

With coolant holes
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.
