Calculations of cutting conditions
Product attributes
Straight bore with standard keyway and driving slot according to DIN 138.
Helix angle = 30°.
Rake angle = 10°.
Very high performance high speed steel with good toughness for milling cutters and for milling of materials up to the strength of 1200 MPa.
For roughing operation and materials of medium and higher strength (up to 1200 MPa), surface roughness Ra 6,3 and more.
Feed direction possibility
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.
