Calculations of cutting conditions
Product attributes
Designed for steels up to 800 N/mm²
Conical lip relief, split point, DIN 1412 form A
Drilling depth 5xD
High speed steel of average performance, it is applicable especially for cutters of smaller diameters and for milling of materials up to the strength of 900 MPa.
Point angle 118°
Right helix
Standard, universal hard layer. In comparison with uncoated tools it provides 300-400% increase in tool life. We recommend cooling.
