- Excellent temperature resistance up to 800 °C
- Very high coating hardness up to 3,000 HV
- Multi-layer design with additional sliding layer ensures extremely low friction values, low adhesion tendency and optimum chip removal
- Stable cutting edge through reduced chip angle
- Sufficient coolant and lubricant must be added for drilling processes and when cutting threads.
- For tool/material assignments, see the overview tables
- For further information, please refer to the individual products.
Before reversing the screw tap, the entire spiral point of the tool must be removed from the drill hole. Failure to do so may cause cutting edges to chip or the tool to break.
