Axial drilling and milling head with offset axes
Premium class tooling system for highest production efficiency - Made in Germany
Collet chuck ER25 DIN6499
Clamping range Ø2-16
For collet 250 430E
When tightening the clamping nut, it is essential to counterhold the tool spindle.
Failure to observe the counterholding may result in damage to the gearbox or drive coupling.
Maximum tightening torque: 90 Nm
Polygonal shaft hub connection
The latest series of our tool systems are equipped with polygonal shaft hub connections. Compared to tool holders with key connections, there are clear technological advantages:
Reduced vibrations of the tool spindle
Significantly increased power transmission
Less gear backlash
EWS.Butterfly-Seal - sealing technology in a class of its own
Speed-related lift-off function of the sealing element
No friction-induced running-in of the spindle
Reduced mold heating by up to 50%
Effective protection against cooling emulsion and dirt particles
Lower repair costs
EWS.Coolant Management - simply clever
Opening and closing of external cooling with just one turn
Coolant flow adjustable
Time saving due to easy handling
