Execution
Functional surfaces hardened and ground, maximum concentricity. Short, robust design, chuck and shank are attached rigidly together. 2000 Super, for clockwise and anti-clockwise rotation, high clamping force due to gear ratio, self-locking against loosening. The chuck does not open when rotating anti-clockwise and braking rapidly from high rotation speeds. Tightened and loosened using an Allen key, making it possible to change tools at the machine
