Abstract (en)
[origin: EP2425951A1] The system (100) has a quick-change tool holder (120) formed for insertion into a quick-change tool holder accommodator of a base part (110). The tool holder has a chisel accommodator for a round-shaft chisel (130) with a longitudinal axis, and a base wrapping part projecting in a radial direction with respect to an insertion direction of the tool holder in the base part. The wrapping part surrounds a support projection at the base part in an inserted condition, and has a contact surface running in the insertion direction inclined to the longitudinal axis and intersecting the axis in an angle. The wrapping part is designed in form of a bent rod or a warped stop bar.
