High-end TiAlN+ coating
- 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

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
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.
