This is our most powerful air cooled HF-spindle. With 2.2 kW, this spindle offers a maximum of torque reserve which can be used to chip different materials with tools up to 10 mm thanks to its ER16 collet taper. For this spindle, no additional coolant aggregates are necessary because of the integrated fan. Thanks to the asynchronous drive technique, the spindle is running very smooth and quiet, up to 12,000 rpm a difference to water cooled spindles isn't even noticeable.
