Zusammenfassung:	A power hand tool including a manually engageable housing, a prime mover within the housing, a tool bit engaging chuck projecting from the housing, power transmission means within the housing and between the prime mover and the chuck; said power transmission is operable to selectively drive the chuck rotatively or reciprocally. The chuck is driven rotatively by a tube driven by the transmission and coupled with the chuck for free relative axial movement and for relative circumferential drive; the chuck is driven reciprocally by an eccentric drive means connected with the transmission and coupled with the chuck for free relative rotation and for reciprocal axial drive.
