High-end coating TiAlN+
- Currently one of the most powerful screw tap coatings on the market for machining hard materials
- Specifically developed for thread cutting
- Extremely high heat resistance up to 800°C
- Very high coating hardness up to 3,000 HV
- Multi-layer design with additional lubricant coating ensures extremely low friction values, low adhesion tendency and an optimum chip removal
Stable cutting edge
The reduced chipping angle stabilises the cutting edge.
- Sufficient coolant and lubricant must be added when cutting threads.
- For the machine tap/material assignments, see the overview tables
