Proto J150WP-M Air Impact Wrench 1/2 in 635 Ft-lb

Product Description

The PROTO J150WP-M is a 1/2 inch drive pneumatic impact wrench built for heavy-duty fastening and removal in professional shop, fleet, and industrial environments. It delivers 635 ft-lb of torque at 10,000 RPM, making it capable of driving and breaking loose large fasteners quickly. Air supply requirements are straightforward: 90 psi inlet pressure, 4.5 CFM air consumption, and a 1/4 inch NPT inlet fitting. The handle-exhaust design directs spent air away from the work area. At 2.9 pounds, it is light enough for extended use without significant fatigue. Licensed mechanics, millwrights, and industrial maintenance techs are the primary users of this tool.

The J150WP-M suits automotive repair, fleet maintenance, heavy equipment service, and general industrial assembly where high torque output in a compact pistol-grip format is required. The pistol grip configuration offers direct control during single-handed operation. A minimum 3/8 inch hose is required to supply adequate airflow to the tool. This wrench is appropriate for both production-line applications and field service work where a reliable 1/2 inch drive air impact is needed.

Key Features

• 635 ft-lb maximum torque output for demanding fastener removal and installation

Compatibility

Designed for use with standard 1/2 inch drive impact sockets and accessories. Requires a compressed air supply delivering a minimum of 90 psi and 4.5 CFM through a 3/8 inch or larger air hose with a 1/4 inch NPT fitting.

Installation Notes

Connection and disconnection should be performed with the air supply depressurized. Always use impact-rated sockets rated for the torque output of this tool — standard chrome sockets are not suitable. Verify the air line and fittings are rated for the operating pressure before use. Follow applicable OSHA and facility safety guidelines for pneumatic tool operation.
