Abstract
A tool clamping device has a spindle insert (10) and an adapter (12) between the spindle insert (10) and a toolholder (14). The adapter (12) can be pushed axially along the longitudinal axis (16) of the device into the holder (18) of the spindle insert (10), and can be fixed by a fastener (20). In addition to the fastener (20), between the spindle insert (10) and adapter (12), a torque transmission (22) establishes a positive connection between the spindle insert (10) and adapter (12). In this way, the fastener (20) is relieved of stresses and loads.
