Abstract: A handpiece, especially for dental purposes, which is constituted of a gripping sleeve with a treating implement at one end thereof which is supported for limited reciprocating pivotal movement about its axis. The implement is drivable through the utilization of an intermediate drive shaft which is arranged within the gripping sleeve and which is similarly drivable in a limited reciprocable pivoting movement about its axis, whereby for producing the reciprocability of the intermediate drive shaft, the end of the intermediate drive shaft which is distant from the implement cooperates with a wobble surface or swash plate arranged at the end of a drive shaft proxime the implement, which drive shaft is rotatably supported within the handpiece. Moreover, a converting device is arranged between the end of the intermediate drive shaft which is distant from the implement and the swash plate, which converts the rotational movement of the drive shaft into a pivotal movement of the intermediate drive shaft.
