Product attributes
Type UNI
more +Designed for universal applications
Chamfer
more +For straight or spiral flutes, for short chipping materials.
Lead of screw thread
ISO Metric coarse thread
TiCN coating
more +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).
