40.5525KR1809N4IK - Axial drilling and milling head, For collet 250 430E (ER25 Ø2-16), with tapered roller bearing, Int. / ext. coolant pmax = 25bar, i = 1:1 (input equal output),
Article number: 171258Axial drilling and milling head
Premium class tool 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
Tapered roller bearings (KR) - extraordinarily loadable.
- Recommended for machining operations with high torques (e.g.: milling operations with large diameters, threading operations, interrupted cut machining)
- Increase of tool life
- Reduction of service intervals
- Simultaneous radial and axial loads can be easily absorbed
Internal cooling
Equipped with high-quality seal kits that can withstand coolant pressure of up to 25 bar.
- 25 bar maximum coolant pressure
- Not capable of dry running
- Change between external and internal cooling possible
- Coolant must be applied to the tool at all times
