Calculations of cutting conditions

Product attributes

Clamping element

more +

Straight shank with clamping flat (Weldon) according to DIN 1835 B.

Tool geometry

more +

Helix angle = 30°. Rake angle = 8°.

Material HSS Co8

more +

Extra high performance high speed steel with good toughness and great temperature resistance. It is applicable especially for milling of materials with high strength, austenitic steels, steels for warm working, etc.

Type N

more +

Universal usage. Suitable for materials up to strength 900 MPa.

Feed direction possibility

TiAlN coating.

more +

Its advantage is in high hardness in higher temperaures, good oxidation resistance and low temperature conductivity. Universal usage with emphasis on high-speed miling without cooling. Siutable for milling of hard materials.
