Abstract

The motor driven hammer drill or impact drilling machine has a stem beater (2) with an exciter casing (8) moving in and out in a longitudinal direction (10) in translatory manner. A driven device (16) is provided for the exciter casing. A drive pin (20) is coupled directly or indirectly with the exciter casing in such a manner that the exciter casing is twisted in and out on rotation of a drive shaft (18) practically not around the longitudinal direction. An independent claim is also included for a stem beater (2) for a motor driven hammer drill or impact drilling machine, which has an exciter casing.
