The hammer assembly includes a hammer mechanism configured to apply axial impacts to the output spindle when the hammer mechanism is engaged, and a hammer housing composed of a heat conductive material and supporting at least a portion of the hammer mechanism. The hammer housing is at least partially disposed inside of a portion of the clutch housing
