A saw for cutting hard materials, and including a guide rail ( ) securable to a cut component, a support ( ) displaceable along the guide rail ( ), a saw head ( ) including a drive for driving a saw blade, a guide element along which the saw head ( ) is displaceable within predetermined limits and which is arranged on the support ( ) and extends parallel to the drive shaft of the saw blade-driving drive and which extending transverse to a longitudinal extent of the guide rail ( ) and transverse to the longitudinal extent of the guide rail ( ), and a quick release device ( ) provided between the support ( ) and the saw head ( ) for connecting the saw head ( ) with the support ( ).

Saw for cutting of hard materials

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.
