Impact wrench

A power hand tool body has a barrel with a depending skirt portion from which depends an elongated handle. Elongated grooves are formed in opposite sides of the skirt portion and extend between forward and rearward ends thereof, the grooves being part-cylindrical in transverse cross-section and having rectangular cross-section neck portions opening at the sides of the skirt. A hollow tubular grip formed of flexible and resiliently stretchable material has an end portion with part-cylindrical attachment members extending laterally and inwardly from opposite sides thereof so that, when the grip is slipped over the handle, the end portion may be stretched to insert the attachment members respectively into ends of the grooves for retaining the grip in place.

Hand-held tool

A battery-powered driver tool has a tool housing with a socket-type coupler which receives a plug-type coupler of a battery pack in any of four different rotational orientations. Four keys on the battery pack are received in four keyways on the tool housing for non-rotatable engagement, the parts being retained by a split snap ring on the battery pack which cams past four cam shoulders on the tool housing, so that the parts automatically snap-engage and disengage in response to a simple push-pull motion. The battery pack includes a plurality of battery cells connected in series between positive and negative terminals which are designed to respectively engage positive and negative terminals on the tool housing in any of the four rotational orientations of the battery pack. The battery pack has a flat base surface, the parts being designed so that the tool/battery pack combination can be stood on the base surface in one rotational orientation of the battery pack.
