Dental tool holder |
摘要 |
A dental toolholder (2) has an endodontic filing tool (18) which is clamped in the toolholder so as to be secured against rotational and axial movements. A vibrating movement is impressed on the tool. The tool (18) can be clamped at its rear shaft end with a slight play and the vibrations can be imparted to the tool at its front shaft end (15). This part encloses the front shaft end (7b) with slight play and comprises a cylindrical recess whose cross-sectional shape has a constant-diameter configuration. Accordingly, the tool is set into a swinging movement perpendicular to its axis. The structural component part (15) rotates preferably at approximately 20,000 rpm.
