Description
Version:
The special front cutter geometry with unequal spacing permits process-reliable circular thread milling across a wide spectrum of materials. The side cooling grooves on the shank ensure outstanding coolant feed without weakening the tool core and thus offer maximum process reliability even in unstable conditions. All tools have left-hand cutting and are suitable for right-hand and left-hand threads.
- Significantly reduced vibrations due to irregular cutting edge spacing.
- New coating for optimum wear resistance.
- Cooling grooves on the shank for targeted coolant feed.
- Corrected thread profile for avoidance of profile distortions.
