The STEELMAN 60355 1-Inch Drive Heavy Duty Air Impact Wrench with 6-Inch Extended Anvil is ideal for standard and heavy-duty farm, construction, and industrial use. The adjustable throttle control and trigger features four speeds, three forward and one reverse, to harness the powerful 4,000 RPM free running pneumatic motor and generate up to 1,900 ft-lb of torque. The lightweight aluminum body conceals a twin hammer internal mechanism that is machined with durable titanium and tungsten alloys to deliver smooth and balanced, yet hard-hitting blows to help remove fasteners with less jarring in the hands of the operator. The 6-inch extended anvil allows the driver to easily access recessed and normally hard to reach nuts and bolts without the need of an additional extension bar. Compatible with 1-inch square drive impact sockets, extensions, torque sticks, and accessories. The tool connects to 1/2-inch or larger pneumatic lines through the 1/2-inch NPT threaded inlet at the base of the handle and uses 10 CFM of compressed air. Includes an air tool oil bottle.
