- For quick stretching and remove the drilling tool; no keys needed.
- Higher elasticity, solid retaining ring, short design, less weight.
- Automatically nachspannen when drilling proportionally to the pull-out elasticity. So the maintenance of spann power even hard to use.

For quick clamping and loosening of the drilling tools, without a key. Higher clamping force, solid retaining ring, short construction, less weight. Self-tensioning when drilling proportional to the clamping force. This maintains the clamping force even when used hard.
Type Supra: Heavy industrial design for stationary drills.
Type Supra S and M: lightweight design, mainly for hand-held drills.
