High-end TiAlN+ coating
- One of the most powerful screw tap coatings currently on the market for machining hard materials
- Specially developed for thread machining
- Extremely high temperature resistance up to 800 °C
- Very high coating hardness up to 3,000 HV
- Multi-layer design with additional lubricant layer ensures extremely low friction values, low adhesion tendency and optimal chip removal
Stable cutting edge
The reduced rake angle stabilises the cutting edge.
Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze
- Sufficient coolant and lubricant must be added when cutting threads.
- For the machine tap/material assignments, see the overview tables
Datasheets(X)
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.
