Product attributes
Morse taper shank according to DIN 228 A.
Helix angle = 45°.
Rake angle = 20°.
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 machining of soft materials, for example aluminium and non-ferrous metals.
