Abstract

Perfections in drilling hammers of the type in which the driving force is distributed in a rotational movement to rotate the tool and in a percussion movement directed in the direction of the axis of the tool, where for the transmission of the rotation movement is provided between the tool holder and the drive wheel, a coupling piece attached to the rotation with the tool post, which by axial displacement by means of an adjusting member, can be brought to a position that engages with the drive wheel, to a position of rotation in vacuum and in a position immovable with respect to the casing of the hammer drill, characterized in that the coupling piece for immobilization, projections or necklines that engage with corresponding necklines or projections of the casing.
