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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e635 ft-lb maximum torque output for demanding fastener removal and installation\u003c\/li\u003e\n\u003cli\u003e10,000 RPM free speed with 1,650 impacts per minute for fast cycle times\u003c\/li\u003e\n\u003cli\u003ePistol grip handle for controlled, comfortable single-handed operation\u003c\/li\u003e\n\u003cli\u003eHandle exhaust routes spent air away from the operator and workpiece\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT inlet with 3\/8 inch minimum hose size requirement\u003c\/li\u003e\n\u003cli\u003eLightweight at 2.9 pounds for reduced fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2 inch drive impact sockets and accessories.
