Calculations of cutting conditions
Product attributes
Straight shank with clamping flat (Weldon) according to DIN 1835 B.
Helix angle = 30°.
Rake angle = 10°.
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.
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.
