Abstract: A power tool includes a housing and a motor disposed in the housing. The motor has an axial face and a motor shaft extending from the axial face. The power tool also includes a spindle driven by the motor about an output axis, a motor plate having a central opening defining an inner surface of the motor plate, and a tolerance ring coupled to the inner surface of the motor plate. The tolerance ring has deformable waves. The motor plate is coupled to the motor by engagement of the deformable waves with the motor to take up tolerances between the motor plate and the motor.

Abstract: A handheld punch tool includes a housing defining a first axis, a motor contained within the housing, the motor having a motor shaft defining a second axis, and a head coupled to the housing and rotatable relative to the housing about a third axis. The head includes a drive member reciprocable along the third axis in response to rotation of the motor shaft about the second axis and a punch coupled to the drive member and reciprocable along a fourth axis in response to reciprocation of the drive member along the third axis. The third axis is perpendicular to the first axis, and the fourth axis is parallel to the third axis such that rotation of the head about the third axis varies a position of the punch relative to the housing.

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.
