The power transmission in the SDS-Quick System works via a form-fit, in the conventional cylinder shaft system via a friction locking.
While the connection between the drill and the jaw in the cylinder-shaft system is based on friction, the power transmission between the shaft and the drill chuck is ensured form-locking in the SDS-Quick System.
This means less friction losses and hence an optimum transmission of the torque.
The Quick-Change system permits one to change the drill in a few seconds without any tool.
SDS-Quick drill can also be used in the conventional three-jaw drill chucks (with or without key).
