Abstract: A power tool includes a housing, a drive mechanism supported within the housing, a spindle operatively coupled to an output of the drive mechanism such that torque from the drive mechanism rotates the spindle about an axis, and an accessory removably coupled to the housing. The drive mechanism is configured to supply up to a first maximum torque to the spindle when the accessory is removed from the housing. The drive mechanism is configured to supply up to a second maximum torque to the spindle greater than the first maximum torque when the accessory is coupled to the housing.
