Calculations of cutting conditions
Product attributes
Straight shank with clamping flat (Weldon) according to DIN 1835 B.
For roughing operation and materials of medium and higher strength (up to 1200 MPa), surface roughness Ra 6,3 and more.
Feed direction possibility
Company norm
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.
