Abstract

Perfection improvements in percussion drills, with a drive motor with invertible direction of rotation, incorporated in a housing, which through a gear wheel switchable to drill service and percussion drilling service, drives a working spindle to that in the percussion drilling service, axial drums are administered with the aid of a movable mass against a spring by means of notches, characterized in that the movable mass is a toothed wheel of the gear wheel gear, and because on the front side of this the toothed wheel is made with first notches that act in cooperation with second geometrically developed notches on the front side of another toothed wheel.
