Description
Version:
- Taper ground internally and externally.
- Shanks hard turned.
- With RFID/Balluffchip bore.
- The collet is clamped by a threaded connection from behind through the chuck, no clamping nut required!
Advantage:
Extremely slim design permits machining of components where access is difficult, e.g. for toolmaking and mould-making.
Large working range and optimised contour for reduced vibration. Cooling with the collet by the tool or along the shank.
Large working range and optimised contour for reduced vibration. Cooling with the collet by the tool or along the shank.
