Description
Version:
- Taper shank, spigot, and all contact surfaces are ground at the collar.
- With Balluff/RFID chip bore.
- Increased collar contact surface.
Advantage:
The heavy metal core specially matched to the arbors gives optimum machining results even with long overhangs:
- Saves time, because allows use of the maximum machining parameters.
- Smooth running and thus perfect surface quality results.
- Saves costs, because tool life is increased.
- Less vibrational stress on the machine headstock.
Supplied with:
Cutter lock screw and drive dog.
Optional extras:
Note:
Balance quality G 6.3 dependent on the maximum operating speed.
