Abstract

A hammer drill comprising a housing 1 and a tool holder 10 which is axially displaceable relative to the housing 1. During rotary drilling the tool holder 10 is supported in the axial direction against the housing 1. During percussion drilling radial play exists between the tool holder 10 and a percussion hammer 7 guided in the housing 1 as well as between the percussion hammer 7 and the housing 1. To cancel this play and provide for rotary drilling the tool holder 10 has, at its rearward end, a centering adjoint-piece 11a which when engaged with a centering bore 1e makes possible a direct centering of the tool holder 10 on the housing 1. <IMAGE>
