Calculations of cutting conditions
Product attributes
Straight shank with clamping flat (Weldon) according to DIN 6535 HB.
For roughing operation and materials of lower and medium strenght.
Feed direction possibility
Oil coolant.
Company norm
Helix angle = 25°.
Rake angle = 15°.
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.
