It delivers 2,150 ft\/lb of torque at a free speed of 5,160 RPM, making it suitable for large-diameter fastener removal and installation on heavy equipment, trucks, and structural assemblies. The tool operates at 90 psi with an air consumption of 10 CFM through a 1\/2-inch NPTF inlet. A directional exhaust port lets the operator redirect airflow away from the work surface and the technician. A built-in clutch mechanism supports controlled torque application during general maintenance tasks.\u003c\/p\u003e\n\u003cp\u003eThis wrench is designed for use by heavy-equipment mechanics, fleet maintenance technicians, and industrial assembly teams working with large fasteners where a standard 1\/2-inch or 3\/4-inch drive tool lacks sufficient torque output. The D-handle grip provides a stable two-handed hold during extended use on wheel lugs, flange bolts, and suspension components. Low-vibration design reduces operator fatigue during repetitive operations. It requires a minimum 1\/2-inch air supply hose and a compressor capable of sustaining at least 10 CFM at 90 psi for consistent performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2,150 ft\/lb (2,900 N\/m) of torque output for heavy-duty fastener work\u003c\/li\u003e\n  \u003cli\u003e5,160 RPM free speed with 500 blows per minute for rapid fastener cycling\u003c\/li\u003e\n  \u003cli\u003eDirectional exhaust keeps debris and airflow clear of the operator and work area\u003c\/li\u003e\n  \u003cli\u003eD-handle configuration provides stable grip and control under high-torque loads\u003c\/li\u003e\n  \u003cli\u003eBuilt-in clutch mechanism supports controlled engagement for general maintenance applications\u003c\/li\u003e\n  \u003cli\u003eLow-vibration design reduces operator fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty OEM-style pneumatic impact wrench suited for industrial maintenance, fleet service, and heavy equipment repair applications requiring a 1-inch square drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified mechanics or pneumatic tool technicians familiar with compressed air systems. Before connecting to an air supply, verify that the compressor outlet pressure does not exceed the tool's rated 90 psi operating pressure. Use a minimum 1\/2-inch inside-diameter air supply hose and ensure all fittings are secure before applying air. Disconnect the air supply before performing any maintenance, changing sockets, or inspecting the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 2,150 ft\/lb (2,900 N\/m)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 5,160 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlows Per Minute\u003c\/strong\u003e: 500 BPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi (6.30 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 10 CFM (4.80 LPS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/2 inch NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hose Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: D-Handle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Directional Exhaust\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoise Level\u003c\/strong\u003e: 111 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 21.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 24.42 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Style\u003c\/strong\u003e: Heavy Duty\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: 8941077820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51538983026994,"sku":"8941077820","price":986.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3309bbfc87a48234c3b3697c1eba378c.jpg?v=1785831738","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-8941077820-air-impact-wrench-1-in-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
