It runs on compressed air at 90 psi and delivers 0.5 horsepower at a rated speed of 20000 RPM, with a speed range spanning 18000 to 24999 RPM. The 1\/4-inch collet accepts standard mounted points, carbide burrs, and abrasive wheels. Rear exhaust routes air away from the workpiece, keeping the work zone clear of debris and coolant. Overall length is 8.125 inches. Licensed mechanics, machinists, fabricators, and pipefitters are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis grinder is suited for tight-clearance work where a straight grinder cannot reach. The 7-degree offset angle handle positions the spindle at an angle to the body, making it practical for port work, weld blending in confined areas, and die and mold finishing. It is commonly used in automotive shops, aerospace fabrication, metal fabrication facilities, and maintenance repair operations. Air consumption is 24.99 CFM at 90 psi, so an adequately sized compressor and supply line are required to maintain consistent tool performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5 HP pneumatic motor rated at 20000 RPM for efficient material removal\u003c\/li\u003e\n  \u003cli\u003eSpeed range of 18000 to 24999 RPM accommodates a variety of mounted abrasives and burrs\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch collet accepts standard carbide burrs, mounted points, and abrasive wheels\u003c\/li\u003e\n  \u003cli\u003e7-degree offset angle handle provides access in confined spaces and blind areas\u003c\/li\u003e\n  \u003cli\u003eRear exhaust location directs air away from the operator and work surface\u003c\/li\u003e\n  \u003cli\u003eCompact 8.125-inch overall length for use in tight work envelopes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4-inch shank mounted points, carbide burrs, and rotary files compatible with angle die grinders operating at up to 20000 RPM.

Shut off and bleed compressed air from the supply line before changing collets or accessories. Ensure the air supply is regulated to 90 psi and that the supply line and fittings are rated for the required CFM to avoid speed drop under load. Inspect the collet and accessory shank for wear or damage before each use, and never exceed the RPM rating marked on the abrasive or burr.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 0.5 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Speed\u003c\/strong\u003e: 20000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed Range\u003c\/strong\u003e: 18000 to 24999 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi (6.21 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 24.99 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Angle (7-degree offset)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Rear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: DYNABRADE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNABRADE","offers":[{"title":"Default Title","offer_id":51541245002034,"sku":"52222","price":774.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/993a55b06e27e720f14e6b37f4c57f29.jpg?v=1785870623","url":"https:\/\/voomisupply.com\/products\/dynabrade-52222-air-die-grinder-0-5-hp-1-4-inch-collet","provider":"Voomi Supply","version":"1.0","type":"link"}
