Abstract
A modular handheld electric tool system comprises a handle, a motor module and a tool head. The handle includes a handle housing with an elongate portion configured to provide a grip, a handle electrical coupling on the handle housing, a circuit including a tool switch in the handle housing, the tool switch connected between a power supply and the handle electrical coupling. The motor module including a motor casing that holds an electric motor, a motor electrical coupling on the motor casing that is complementary to the handle electrical coupling and electrically connected to the electric motor, and a rotary output mounted to the motor casing and driven by the electric motor. At least one tool head is releasably attachable both to the motor module via a tool-less tool-head-to-motor mechanical coupling, and to the handle via a tool-less tool-head-to-handle mechanical coupling, the tool head including an accessory and tool body wherein, to supply torque to the accessory from the electric motor, a rotary input mounted to the tool body engages the rotary output of the motor module.
