Abstract
A power tool includes a motor having an outwardly extending rotor that defines a drive axis, a housing surrounding the motor, and a gearcase that includes a drive train coupled to the rotor and configured to drive a tool output. The gearcase includes a proximal end and an opposite distal end that is exposed to the outside of the tool forward of the housing. The gearcase includes respective locking elements spaced around the periphery of the gearcase proximal end. A motor mount includes spaced apart locking elements that are configured to engage with respective gearcase locking elements. The proximal end portion of the gearcase is adapted to make contact with the motor mount between the locking elements and then rotate such that the gearcase locking elements engage the motor mount locking elements.
