Calculations of cutting conditions

Product attributes

Clamping element

more +

Straight bore with standard keyway and driving slot according to DIN 138.

Tool geometry

more +

Helix angle = 30°. Rake angle = 12°.

Material HSS Co5

more +

Very high performance high speed steel with good toughness for milling cutters and for milling of materials up to the strength of 1200 MPa.

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.
