Powered by a 2.5 horsepower air motor spinning at up to 12000 RPM, the tool is engineered to cut through hard alloys and weld spatter without bogging down under load. Weighing 4.1 pounds, the compact housing keeps operator fatigue low during extended use. The 5\/8 inch-11 threaded spindle accepts Type 27 grinding wheels, making it compatible with standard abrasive wheel stock commonly found on the job site. Licensed HVAC, pipefitting, fabrication, and industrial maintenance professionals rely on this class of grinder for weld cleanup, surface prep, and stock removal.\u003c\/p\u003e\u003cp\u003eThe 5445MAX fits residential, commercial, and industrial applications wherever compressed air is available. Typical install scenarios include metal fabrication shops, pipe fabrication yards, shipyards, and heavy equipment maintenance bays. The tool requires a minimum 1\/2 inch air hose and connects via a 3\/8 inch NPT inlet. At 76.75 CFM air consumption under load, an adequately sized compressor and supply line are necessary to sustain rated performance during continuous grinding passes. The 9.33 inch overall length keeps the tool maneuverable in tight weld joints and pipe saddles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5 HP pneumatic motor delivers high torque for aggressive material removal on hard alloys\u003c\/li\u003e\n\u003cli\u003e12000 RPM maximum free speed suits Type 27 depressed-center grinding wheels\u003c\/li\u003e\n\u003cli\u003e5\/8 inch-11 threaded spindle accepts standard abrasive wheel stock\u003c\/li\u003e\n\u003cli\u003e4.1 pound tool weight reduces operator fatigue during all-day use\u003c\/li\u003e\n\u003cli\u003e3\/8 inch NPT air inlet with 1\/2 inch minimum hose size requirement\u003c\/li\u003e\n\u003cli\u003e9.33 inch overall length for maneuverability in confined grinding applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Type 27 grinding wheels with a 5\/8 inch-11 arbor thread. Air supply requirements must meet or exceed the tool's rated consumption of 76.75 CFM at load to maintain full performance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of pneumatic angle grinders should be performed by qualified personnel familiar with compressed air tool safety and applicable ANSI B11 and OSHA 1910.243 standards. Always shut off and bleed the air supply line before mounting or removing grinding wheels, and confirm the wheel's rated RPM meets or exceeds the tool's 12000 RPM maximum free speed before use. Inspect the wheel for cracks or damage before each use and use the appropriate guard as required by the wheel manufacturer and applicable safety codes. Ensure the air supply line fittings are rated for the operating pressure and that the hose diameter meets the 1\/2 inch minimum requirement to avoid pressure drop under load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Power\u003c\/strong\u003e: 2.5 HP (1.86 kW)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Free Speed\u003c\/strong\u003e: 12000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Output\u003c\/strong\u003e: 5\/8 inch-11 Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9.33 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Consumption at Load\u003c\/strong\u003e: 76.75 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Inlet Size\u003c\/strong\u003e: 3\/8 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Hose Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INGERSOLL RAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5445MAX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL RAND","offers":[{"title":"Default Title","offer_id":51524928209202,"sku":"5445MAX","price":614.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1aa1fd2559d1b59c8e925a6a40f83866.webp?v=1785461932","url":"https:\/\/voomisupply.com\/products\/ingersoll-rand-5445max-air-angle-grinder-2-5-hp","provider":"Voomi Supply","version":"1.0","type":"link"}
