Calculations of cutting conditions
Product attributes
Straight shank with clamping flat (Weldon) according to DIN 6535 HB.
Helix angle = 37/38°.
Rake angle = 6°.
End face design
Carbide materials are characterised by high compressive strength, high hardness and therefore high wear resistance, but also limited flexural strength and toughness.
