  • Patent number: 6506006
    Abstract: A power hand tool includes a body, an electric motor, an output driving shaft rotatable by the motor, a holder for holding a cutting bit and rotatable by the shaft for, in turn, rotating the cutting bit for cutting, an electrical switch provided on the body for controlling operation of the motor, and a detachable handle. The handle has a first, fixed end releasably connected to the body, a middle section extending to form a relatively large gap with the body sufficiently wide to allow the handle to be gripped by a hand, and a second, free end. The free end extends to approach a region on the surface of the body adjacent and not reaching the switch and forms a relatively small gap with the region sufficiently narrow to retain a hand gripping the handle.
