Abstract

A portable electric impact drill wherein an axially reciprocable tool spindle can be driven at two speeds by a gear transmission which is installed in front of a universal electric motor. The tool spindle is movable axially by a rotary or reciprocable selector to assume one of four positions including a first position in which it receives torque from a first gear of the transmission and is driven at a relatively low speed, a second position in which it receives torque from a second gear of the transmission and is driven at a relatively high speed, a third position in which it is disengaged from both gears, and a fourth position in which it receives torque from the second gear and causes an annulus of projections on the second gear to travel along an annulus of projections in the housing of the power tool so that the tool spindle rotates at the higher speed and is caused to perform axial oscillatory movements.
