Abstract: A tapping tool for repairing damaged threads on PVC pipe and PVC pipe fittings (e.g. T-connectors, elbows, etc.) includes an elongate shaft with a handle member fixed to a proximal end and a head fixed to an opposite distal end. A threaded tap formed of hardened steel is positioned and disposed on the head for forced, threaded engagement with the threads of the PVC pipe or fitting. Manual rotation of the handle serves to advance and withdraw the head along the threads of the PVC pipe or fitting as the tap cuts and reshapes damaged threads, thereby restoring the threads of the PVC pipe or fitting to a uniform, functional condition.

Abstract: A rotary tool such as a helix drill and an end mill for example, is manufactured by forming a blank by an extrusion process, and then sintering the blank. During the extrusion, a mixture is passed through a die which provides a cylindrical shape to the outer peripheral surface of the mixture. A plurality of jaws are disposed downstream of the die for conducting the mixture. Each jaw includes a helical ridge for engaging the outer surface of the extrudate to cause a helical groove to be formed therein which constitutes a chip flute in the tool. During the extrusion, the jaws are moved away from the mixture to terminate formation of the chip groove, whereby a shank portion of the tool is formed.

Abstract: A tool, of the type suitable for use only in the drilling only mode of a rotary hammer. The tool has a shank portion at its rearward end and a drilling tip at its forward end wherein the shank portion can be releaseably locked in a tool holder of a rotary hammer by at least one locking body of the tool holder engaging a closed groove formed on the shank. The forward end of the closed groove is positioned sufficiently close to the rearward end of the tool that the rearward end of the tool is always located in the tool holder forwardly of the most forward position of a hammering mechanism of the rotary hammer. Therefore, if the hammer is inadvertently switched to a hammering mode, the hammering mechanism will not impact the drilling tool and so will not damage it or prejudice the operation of the tool.
