Abstract: A surgical dental or dental technician's angled vibration member consisting of a gripping sleeve portion having a drive shaft supported therein, and an end or head sleeve portion which is arranged at one end of the gripping sleeve portion, whose axis extends at an angle to the axis of the gripping sleeve portion and within which an impact piston is axially reciprocable for a return stroke through the intermediary of an eccentric located on the end of the drive shaft. The impact piston, for the engagement of the eccentric, includes a side recess with a stop, which is provided along its edge and wherein, after passing beyond the stop, has associated therewith an operating spring for effecting the operating stroke, the spring being stressed prior to reaching the stop whereby the impact piston will during its operating stroke impart an impact to an axially movably supported tamping-type vibration tool located at the end inserted in the interior of the head sleeve portion.
