Abstract

A clamping chuck for securing a tool in a drilling device can be used for transmitting rotary and/or percussion motion to the tool. Independently adjustable guide jaws and at least one engaging element are mounted in the chuck. The guide jaws can hold a tool shank in a frictional engagement while the engaging element can fit into a recess in the surface of the tool shank. With such separate adjustment, the guide jaws can be used alone or in combination with the engaging element for holding the tool shank.
