Pro-source Pro-SM-47-4154P 1 in Drive Air Impact Wrench

Product Description

The PRO-SOURCE Pro-SM-47-4154P is a heavy-duty pneumatic impact wrench built for high-torque fastening work in professional shop and field environments. It features a 1-inch square drive and delivers 200 to 1,200 ft/lb of torque at up to 5,500 RPM, making it suited for demanding applications on large fasteners, heavy equipment, and commercial vehicle service. The pistol grip handle provides a familiar, controlled hold during operation, and the handle-mounted exhaust directs air discharge away from the work surface. This tool is installed and operated by automotive technicians, heavy equipment mechanics, and industrial maintenance professionals.

This impact wrench is designed for stationary and mobile service bays where high-output pneumatic tools are standard. It connects to a shop air supply via a 3/8-inch inlet and requires a minimum 1/2-inch air hose for adequate flow. Operating pressure is 90 psi with an air consumption rate of 9.6 CFM, so a compressor with adequate capacity and delivery volume is necessary for sustained performance. Typical applications include truck and fleet service, industrial assembly lines, and heavy equipment repair where 1-inch drive tooling is the standard.

Key Features

• 1-inch square drive with 200 to 1,200 ft/lb torque output range
• 5,500 RPM free speed with 950 impacts per minute
• Pistol grip handle style for controlled single-hand operation
• Handle exhaust directs airflow away from the work area
• 3/8-inch NPT air inlet compatible with standard shop fittings
• Requires 90 psi operating pressure and 9.6 CFM air supply

Compatibility

Designed for use with standard 1-inch drive impact sockets and accessories. Requires a pneumatic supply capable of delivering at least 90 psi and 9.6 CFM through a minimum 1/2-inch diameter air hose.

Installation Notes

Installation and operation should be performed by a qualified mechanic or trained technician familiar with pneumatic tooling. Before connecting to an air supply, verify that the line pressure does not exceed the rated operating pressure of 90 psi. Use a properly sized air hose of at least 1/2-inch inner diameter to avoid flow restriction and reduced tool performance. Inspect the inlet fitting and coupler for leaks before each use.
