Abstract
A tool bit chuck for drilling and chiseling bits has an axially extending receiving sleeve (1) with an opening (3) therethrough in which latching elements (9) are radially displaceably supported. The latching elements (9) are radially displaceable by a spring loaded axially displaceable actuating element (10). An actuating sleeve (12) laterally encloses and is axially displaceable relative to the receiving sleeve (1). Connecting members fix (6, 13) the actuating sleeve to the receiving sleeve. The actuating sleeve (12) has a stop (14) cooperating with the actuating element (10) for applying an axial force to the actuating element for assisting in centering the drilling or chiseling bit.
