A hand tool comprising a head portion, a shaft, and a grip component is provided. The grip component and the shaft form a handle of the hand tool. The grip component is a reverse-molded component formed by: forming the external portion of the grip component by molding a first thermoplastic elastomer (TPE) material or thermoplastic urethane (TPU) material into a shell that surrounds a first cavity; after forming the external portion; placing the shaft into the first cavity; and, after the external portion is formed and the shaft is placed into the first cavity, forming the inner portion of the grip component by injecting a second TPE material or TPU material into the first cavity and onto the shaft. The first TPE or TPU material has a first level of hardness, and the second TPE or TPU material has a second level of hardness lower than the first level.

A removable attachment assembly for a ninety degree drill assembly, which includes a base member and a securement assembly secured to the base member for releasably securing the base member to a housing of the ninety degree drill assembly. The removable attachment assembly further includes a cushion member releasably securable to the base member.

A hand-held tool comprises a tool part and a handle surrounding a section of the tool part and connected to same in a torque-transmitting manner. The tool part comprises a connection contour used to connect the handle in a torque-transmitting manner at least in some areas, in a section surrounded by the handle. The handle comprises an inner handle piece which can be connected to the connection contour and surrounds same in a torque-transmitting manner. With the inner handle piece slid onto the connection contour, one or more outwardly-open casting channels are provided between the two parts. The handle further comprises an outer handle piece made of plastic, which during the course of a plastic moulding process is moulded around the unit comprising the tool part which has an inner handle piece connected to the connection contour thereof, wherein the at least one casting channel is at least partially filled with the plastic material which forms the outer handle piece. A method is also described for producing such a hand-held tool.

A metal hand tool including a handle attached to a blade piece and method of construction. The blade piece includes a blade opposite an elongated tang. The handle is made up of two, welded, symmetrical handle halves, each handle half having an opening for receiving a hang hole piece and a notched distal end for forming a handle opening to receive the blade piece elongated tang. In an embodiment, the handle includes a curved distal end accommodating a curved welded connection between the blade piece and the handle. The hand tool further includes a hang hole piece configured for placement through the hang hole openings in the handle and for welded connection to the handle. In an embodiment, the elongated tang includes a hang hole opening through which the hang hole extends. Some embodiments further include one or more tang guide pieces welded to the interior of the handle.

A tool assembly includes a handle and a connection end which is connected to the handle by way of blow molding or ultra-sonic fusion. The connection end can be made by plastic injection molding. The handle can be made by way of blow molding. The connection end has a slot defined axially therein. A blade includes a body and a toothed portion. The toothed portion of the blade is connected to the slot of the connection end. The toothed portion is inserted into the slot of the connection end when the connection end is molded by way of blow molding so that the toothed portion of the blade is connected to the slot of the connection end. The toothed portion has multiple teeth and each tooth includes an inclined edge tapered toward the downward toward the connection end.
