Abstract: A power tool having a housing, a motor, a tool holder driven about an output axis by the motor, and an output element for performing an operation on a workpiece. The tool holder has a locating feature including a tapered portion becoming narrower in a direction away from the surface of the tool holder. The output element has an aperture for receiving the locating feature and a face facing the surface of the tool holder when the locating feature is received. The power tool also includes a flange for transferring a clamping force for urging the output element towards the tool holder and a tab projecting from the flange for finger tightening the flange. A biasing member provides the clamping force toollessly. A gap is defined between the surface of the tool holder and the face when the tapered portion of the locating feature is fully received in the aperture.

Abstract: A cutting tool includes a housing and a pair of cutting blades at least partially extending from the housing. At least a first of the cutting blades is movable. The cutting tool also includes a drive mechanism including a cam and a ratchet mechanism. At least a portion of the ratchet mechanism is drivably coupled to the first cutting blade. The cutting tool further includes a motor for providing torque to the cam to actuate the ratchet mechanism.
