Abstract

A hand machine tool operated with two hands has a machine housing composed of insulating synthetic plastic shells, a fixed, web-shaped main handle formed as a part of the machine housing, an auxiliary handle, a drive including a motor and a transmission, at least one inner housing accommodating the motor and the transmission and surrounded by the synthetic plastic shells, and a tool driven by the drive. The handles, the machine housing, the inner housing and the tool are arranged so that forces applied to at least one of the handles are withdrawn from the machine housing by transferring the forces by the main handle directly to the inner housing without deforming the machine housing and then transferring the forces from the inner housing to the tool.
