Powered by compressed air, it runs at 12,000 RPM and accepts a 4-1\/2 inch grinding wheel on a 5\/8 inch spindle. Operating pressure is 90 psi with an air consumption rate of 40 CFM through a 1\/4 inch NPT rear inlet. A governed motor and high-quality bevel gears help maintain consistent speed under load. The tool weighs 3.5 pounds and measures 10.6 inches in overall length, making it manageable for extended overhead or positional work. A safety lever switch and included exhaust hose round out the working configuration.\u003c\/p\u003e\n\u003cp\u003eThis angle grinder suits metalworking trades including fabricators, pipefitters, ironworkers, and industrial maintenance technicians. It is appropriate for grinding, deburring, and surface preparation on steel and similar materials in both shop and field environments. The rear exhaust with included hose allows debris and spent air to be directed away from the operator or work surface. The 360-degree swivel air inlet accommodates varied hose routing without creating line strain or awkward positioning in tight work areas.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12,000 RPM governed motor maintains consistent wheel speed under load\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch wheel diameter with 5\/8 inch spindle for standard disc compatibility\u003c\/li\u003e\n  \u003cli\u003e360-degree swivel air inlet reduces hose drag and improves maneuverability\u003c\/li\u003e\n  \u003cli\u003eRear exhaust with included exhaust hose directs spent air away from the operator\u003c\/li\u003e\n  \u003cli\u003eSafety lever switch prevents accidental startup\u003c\/li\u003e\n  \u003cli\u003eWheel guard included as standard equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 4-1\/2 inch grinding wheels and accessories with a 5\/8 inch arbor.

Verify that the compressed air supply is shut off and the line is depressurized before connecting or disconnecting the tool. Ensure the air supply is clean and dry, as moisture and contaminants reduce tool life and performance. Always confirm that the grinding wheel is rated for at least 12,000 RPM and is properly seated and guarded before applying air pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 12,000 RPM\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: 40 CFM (20 LPS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Inlet Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Size\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Rear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Safety Lever\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.6 inches (270 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Exhaust Hose, Wheel Guard\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: 8941075452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51544628691250,"sku":"8941075452","price":418.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60782f5548cfeacb575f6aedf5e72b77.jpg?v=1785932020","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-8941075452-air-angle-grinder-4-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
