Calculations of cutting conditions
Product attributes
Clamping element
more +Plain straight shank according to DIN 6535 HA.
Type N
more +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
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.
Company norm
Point shape - form N
more +Conical lip relief, DIN 1412 form N.
Drilling depth 8xD
With coolant holes
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.
