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 = 44-46°. Rake angle = 15°.

End face design - radius

With coolant holes

ta-C coating

more +

ta-C coating is designed for machining non-ferrous metals, aluminium alloys with higher Si content, copper, brass, bronze and plastics. Due to its small thickness, very low coefficient of friction and low tendency to stick, ta-C coating is suitable for materials with a tendency to stick as it prevents build-up on cutting edges.

Type W

more +

For machining of soft materials, for example aluminium and non-ferrous metals.

Feed direction possibility

Oil coolant.

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.
