Powered by compressed air at 90 psi, it delivers 445 ft\/lb of torque and spins up to 8,900 RPM, making it suitable for lug nuts, heavy bolts, and stubborn fasteners in demanding shop or field conditions. The aluminum body keeps weight manageable at 5.5 pounds while maintaining the structural rigidity required for sustained impact use. A friction ring retainer secures the drive socket during operation, and the low-vibration design reduces operator fatigue during extended service intervals. Licensed HVAC techs, plumbers, fleet mechanics, and industrial maintenance crews are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis impact wrench fits residential and commercial maintenance applications where a 1\/2 inch drive air tool is required. Typical scenarios include automotive service bays, mechanical rooms, equipment repair shops, and general industrial facilities with an existing compressed air supply. The 1\/4 inch NPT inlet connects to standard shop air lines, and the pistol grip handle provides control during tight-space fastening tasks. At 14 CFM air consumption, an adequately sized compressor is required to sustain continuous operation without pressure drop.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e445 ft\/lb torque output suitable for heavy fastening and removal tasks\u003c\/li\u003e\n  \u003cli\u003e8,900 RPM free speed with 1,100 blows per minute for rapid fastener driving\u003c\/li\u003e\n  \u003cli\u003eAluminum body construction reduces tool weight while maintaining durability\u003c\/li\u003e\n  \u003cli\u003eLow-vibration design minimizes operator fatigue during extended use\u003c\/li\u003e\n  \u003cli\u003eFriction ring retainer keeps drive sockets securely seated during operation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT inlet for compatibility with standard shop air fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2 inch drive impact sockets and accessories.

Before connecting to an air supply, verify the line pressure does not exceed the rated 90 psi operating pressure. Use a properly sized air hose and fitting rated for the tool's CFM demand, and ensure the quick-connect or threaded 1\/4 inch NPT fitting is fully seated and leak-free before use. Always use impact-rated sockets with this tool — standard chrome sockets are not designed for impact loads and may fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 445 ft\/lb (603.34 N\/m)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 8,900 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlows Per Minute\u003c\/strong\u003e: 1,100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpacts Per Minute\u003c\/strong\u003e: 1,020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 14 CFM (6.61 LPS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Air Pressure\u003c\/strong\u003e: 90 psi (6.30 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Pistol Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRetainer Type\u003c\/strong\u003e: Friction Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27131501\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO PNEUMATIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6151909541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51538992398642,"sku":"6151909541","price":423.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8924221340e019c768d2d21651747af5.jpg?v=1785832079","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-6151909541-air-impact-wrench-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
