Abstract

The invention relates to an electric tool, in particular a battery electric tool, such as a thread-cutting machine, drill, screwdriver machine or similar, comprising an electric motor (7) to drive a tool holder (5), for example for a thread cutter. The electric tool has a switch (8) with an operating member for switching on or off the power supply to the electric motor (7) and an inverter (10) for clockwise/anti-clockwise operation of the electric motor (7). The electric tool may optionally be provided with an electronic circuit (12) for speed control and/or regulation of the electric motor (7) and a short-circuit brake for the electric motor (7). The inverter (10) comprises a power semiconductor (13) for the non-contact inversion of the polarity of the power supply to the electric motor (7). The power semiconductor (13) is optionally controlled for the inversion by the electronic circuit (12) using an inversion signal, in particular, generated by an auxiliary contact (22).
