Abstract
A range of power tools each includes motor and transmission housings with an electric motor and a transmission mechanism mounted respectively therein, with the transmission mechanism using the rotary output of the motor to drive a cutting tool. An intermediate housing is sandwiched between the motor and transmission housings. Each of the motor housings is the same in shape, and the length of the electric motors in each of the power tool is different to the length of the electric motors in the other power tools in the range. The transmission housing is positioned differently relative to the motor housing in each power tool to accommodate the difference in length in the electric motor in that power tool, the shape of the intermediate housing in each power tool varying relative to the other intermediate housings to accommodate the difference positions of the transmission housings relative to the motor housings.
