The STEELMAN 60354 3/4-Inch Drive Heavy-Duty Twin Hammer Impact Wrench is ideal for heavy-duty construction, automotive and industrial use. The variable speed throttle control provides you with 3 forward settings and one reverse for optimum speed control of the powerful 5,000 RPM free running pneumatic motor that can generate up to 956 ft-lb of torque. The tool's twin hammer mechanism is constructed of titanium and tungsten alloys and its outer casing is forged of lightweight aluminum to prevent accidental damage. This heavy-duty design allows this impact gun to deliver smooth and balanced yet hard-hitting blows to help remove fasteners with less jarring in the hands of the operator. Compatible with 3/4-inch square drive impact sockets, extensions, torque sticks, and accessories. Using 7 cubic feet per min (CFM) of compressed air, this tool needs to be connected to minimum 1/2-inch inner diameter compressed air lines to function. Exhaust is redirected out through the handle next to the 1/4-inch NPT threaded inlet. Comes with an air tool oil bottle to keep it running strong and smooth.
