It delivers 450 ft\/lb of torque at 9,000 RPM with 1,400 blows per minute, making it capable of driving and removing stubborn fasteners quickly. The compact aluminum body and pistol grip handle keep the tool maneuverable in tight bays and overhead applications. Air consumption runs at 19.6 CFM at 90 psi, so pairing it with an adequately sized compressor and supply line is essential for sustained performance. A friction ring retainer secures the socket. Handle exhaust directs spent air away from the work surface.\u003c\/p\u003e\n\u003cp\u003eThis impact wrench is suited for residential and commercial automotive service, heavy equipment maintenance, and general assembly work where a 1\/2 inch drive air tool is standard. The ultra-compact tool style makes it practical for underhood and undercarriage work where clearance is limited. It operates on a standard 1\/4 inch NPT air inlet and requires a minimum 3\/8 inch hose for adequate airflow. Technicians in tire shops, fleet garages, and fabrication facilities will find the combination of torque output and compact dimensions well matched to daily production demands.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e450 ft\/lb torque output with 1,400 blows per minute for fast fastener removal and installation\u003c\/li\u003e\n  \u003cli\u003e9,000 RPM free speed for rapid socket engagement\u003c\/li\u003e\n  \u003cli\u003eCompact aluminum body reduces tool weight and fatigue during extended use\u003c\/li\u003e\n  \u003cli\u003ePistol grip handle with handle exhaust directs air away from the operator\u003c\/li\u003e\n  \u003cli\u003eFriction ring retainer keeps sockets secured during operation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPTF inlet compatible with standard shop air fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pneumatic impact wrench accepting standard 1\/2 inch drive impact sockets and accessories.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified technician familiar with pneumatic tool safety. Before connecting to an air supply, verify the compressor output meets the 90 psi operating pressure and that the supply line is at minimum 3\/8 inch diameter to sustain 19.6 CFM demand. Always connect and disconnect the air line with the tool trigger in the unpressed position. Sound levels reach 106 dB during operation, so appropriate hearing protection is required per OSHA guidelines.\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\u003eMaximum Torque\u003c\/strong\u003e: 450 ft\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 9,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlows Per Minute\u003c\/strong\u003e: 1,400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 19.6 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating 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 NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hose Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Pistol Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Handle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRetainer Type\u003c\/strong\u003e: Friction Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Style\u003c\/strong\u003e: Compact\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSound Level\u003c\/strong\u003e: 106 dB\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: 8941077320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51544664080690,"sku":"8941077320","price":261.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4daf7b7eabc94e00c3a3c823488d624.jpg?v=1785932965","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-8941077320-air-impact-wrench-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
