FIELD: electrical engineering.

SUBSTANCE: invention relates to electric tool. Tool comprises housing, engine, located in housing, planetary reduction gear and gear wheel with internal gearing. Planetary reduction gear comprises multistage satellites and multistage carrier, each of which is configured to maintain satellites. With last stage carrier bearing is assembled. Gear wheel with internal gearing is selectively moved with sliding between extended position, in which it is located behind said bearing and is engaged with toothed section on carrier of last stage, and with satellites of last stage, and retracted position, in which gear wheel with internal gearing is engaged only with satellites of last stage. Said toothed section on carrier of last stage is made in form of separate gear wheel, which is assembled with carrier of last stage from its rear side.

EFFECT: result is reduced dimensions of electric tool housing.
