Electro rotary hammer, characterized by comprising inside a housing properly, an electric motor at the end of whose axis, is provided a crankpin to which is fixed a tool shaft connecting rod that prints movement to a python that runs through the inside of a cylinder, whose head, hits or not on the rear end of a tool axle, for which it has at the outer end of the appropriate coupling, this shaft being provided with rotation movement transmitted by parallel tree which in turn is moved by a pair pinion crown between this and the motor shaft. The transmission of rotation of this shaft to the tool axis is made through a double friction beater that stops when one. High pressure on the tool overcomes the resistance of the axial spring available to it and is introduced by placing it within reach of the piston or its pneumatic effects when the head of the shaft rests on the leading edge of the cylinder.
