ABSTRACT:
An angular attachment to a rotary and percussive power machine, such as a hammer drill, includes a rotary power input tubular member driven by a rotary part of the power machine, a tubular power output supported for rotation at an angle relative to the axis of rotation of the power input member and including a holder for a rotary and percussive work tool. The tubular power input and output members are interconnected by an intermediate power transmission. A device for transmitting impacts from the percussive part of the power machine includes two guiding channels arranged in alignment with central bores of the tubular power input and output members and each enclosing at least one impact deviating element. The impact deviating elements are in sliding engagement with each other and with a corresponding coupling member arranged in respective contact bores of the power input and output members.
