The extremely stable, Longlife screw tap for machining hard-to-machine materials (such as Hardox) with extremely high strengths from 1000 up to 1400 N/mm², e.g. excavator shovels, lorry attachments, armour plating, snow ploughs, agricultural machinery, etc.

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 from 100 % PCR (recycled plastic from household waste) and 100 % recyclable

Notice
  • Sufficient coolant and lubricant must be added when cutting threads.

  • For the machine tap/material assignments, see the overview tables
