It accepts 4-1\/2 inch grinding wheels via a 5\/8-11 spindle and spins at 12,000 RPM at a rated supply pressure of 90 psi. Air consumption runs at 29.7 CFM, so it requires a capable compressor and adequate line sizing. The aluminum alloy side handle and helical bevel gear drive are standard features on a tool intended for sustained production use. Licensed mechanics, pipefitters, ironworkers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis angle grinder fits general metalworking applications including weld bead removal, deburring, cutting with appropriate wheels, and surface preparation before coating. The front exhaust directs air away from the work surface and the operator, which matters in confined or overhead work positions. A 1\/4 inch NPT air inlet keeps the tool compact. The keyless adjustable guard allows repositioning without additional tooling, and the triggerlock feature reduces operator fatigue during extended runs. Suitable for shop, field, and maintenance applications where a consistent 90 psi air supply is available.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-1\/2 inch wheel capacity with 5\/8-11 spindle thread\u003c\/li\u003e\n  \u003cli\u003e12,000 RPM no-load speed at 90 psi supply pressure\u003c\/li\u003e\n  \u003cli\u003eHelical bevel gear design for smooth, efficient power transfer\u003c\/li\u003e\n  \u003cli\u003eKeyless adjustable protective guard for quick repositioning\u003c\/li\u003e\n  \u003cli\u003eTriggerlock reduces hand fatigue during continuous operation\u003c\/li\u003e\n  \u003cli\u003eFront exhaust directs airflow away from the work surface and operator\u003c\/li\u003e\n  \u003cli\u003eAluminum alloy side handle construction\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, cutting, and flap disc wheels with a 5\/8-11 arbor, connected to a compressed air system supplying a minimum of 90 psi and adequate CFM capacity through a 1\/4 inch NPT air line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified personnel familiar with pneumatic tool safety and applicable OSHA standards for abrasive wheel equipment. Always depressurize the air line and verify zero pressure at the inlet before mounting or changing wheels. Use only wheels rated at or above 12,000 RPM and sized for 4-1\/2 inch grinders; inspect wheels for cracks or damage before each use. Ensure the air supply is clean and dry, and use a properly sized regulator and filter-lubricator in the supply line.\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\u003eSpindle Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo-Load Speed\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: 29.7 CFM\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\u003eExhaust Location\u003c\/strong\u003e: Front\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Aluminum Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\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: 6151957222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51540292174130,"sku":"6151957222","price":480.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/daaaf83609a01acf19ed142ec9e4d321.jpg?v=1785851348","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-6151957222-air-angle-grinder-4-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
