Powder-Actuated Tool


a tool or device powered by a powder charge. Such tools are used for various assembly and fitting operations. They are used to drive fastenings, such as studs, into concrete, brick, metal, and other structural members so that electrical, plumbing, and other fixtures can be attached. They are also used for punching holes in sheet metal and items made from rolled sections, for sawing, cutting, and crimping metal sections and cables, for riveting and tightening threaded connections, and for the press fitting of parts.

The most widely used powder-actuated tools are stud drivers used in civil engineering. These have a single or multiple charge that varies, depending on the operation; this charge, as a rule, controls the strength of the impact. Devices powered by powder charges are usually operated by the blow of a hammer; all powder-actuated tools are equipped with a special blocking device that prevents accidental spontaneous firing.

Powder-actuated tools offer numerous advantages. They operate independently of power sources, substantially increase labor productivity by their rapid action, and provide convenient handling and simple maintenance.
