The professional tool for machining of aluminium and aluminium alloys ≤ 10% silicon. Also suitable for long-chipping plastics, zinc and copper.

Rake precisely tailored to aluminium



Reduced risk of chipping on the cutting edges of the tool


Optimised microgeometry



Excellent chip removal


The spiral point tap and the smoothed surface in plain design minimise material adhesions and ensure excellent chip removal.



Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze

Notice
  • When thread cutting, sufficient coolant and lubricant must be added.

  • See overview tables for machine tap/material assignments
