Product attributes
Designed for universal applications
For straight or spiral flutes, for short chipping materials.
Lead of screw thread
ISO Metric coarse thread
Provides high hardness and at the same time good toughness. Its advantage is in low friction ratio. It is applicable for boring of steels with high strength. It has a lower temperature stability – the cooling is necessary (for example with emulsion).
Angle of thread
Thread standard
High performance high speed steel with 3% vanadium content.
