Abstract
Hand tool with an apparatus housing (2) in which the are movably mounted a rotary portion (8) and a reciprocating slide (10) non-rotatably but displaceably mounted in the housing, said slide serving as a holder for a tool (12). The rotary portion (8) has an oblique shaft (32) with a rolling bearing device (36) mounted thereon, which converts the rotation of the rotary portion into a reciprocating movement of the displaceable portion (10). The rolling bearing device (36) comprises one or two rolling bearings with outer ring surface areas, via which the bearing device is in direct driving contact with a driver element (52) at the end of the displaceably mounted slide (10). The driver element (52) is in direct engagement with the outer rings (48, 50) of the bearing device via opposite lateral surfaces (54, 56).
