It accepts a 1\/4 inch collet and runs at 24000 RPM, powered by a 0.5 HP air motor. The tool requires a 90 psi supply at 26 CFM and features a front exhaust orientation that directs airflow away from the work surface. At 1.5 pounds, it is light enough for extended overhead or confined-space use. Installed by machinists, tool and die technicians, and general fabrication professionals, the 51303 suits both production floor and maintenance applications.\u003c\/p\u003e\u003cp\u003eThe 51303 is designed for straight-line grinding and finishing tasks where a compact, lightweight pneumatic tool is needed. Its 7 inch overall length fits comfortably in tight clearances around fixtures and weldments. The front exhaust design keeps debris and airflow directed forward, away from the operator, making it a practical choice for close-tolerance deburring, die work, and porting on ferrous and non-ferrous materials in both shop and field settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24000 RPM free speed delivers consistent stock removal on hard materials\u003c\/li\u003e\n\u003cli\u003e1\/4 inch collet accepts a wide range of standard mounted points, carbide burrs, and abrasive bits\u003c\/li\u003e\n\u003cli\u003e0.5 HP air motor provides reliable power without adding bulk\u003c\/li\u003e\n\u003cli\u003eFront exhaust directs airflow away from the work surface and operator\u003c\/li\u003e\n\u003cli\u003e7 inch overall length fits confined spaces and tight fixture clearances\u003c\/li\u003e\n\u003cli\u003e1.5 pound tool weight reduces fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pneumatic die grinder accepting standard 1\/4 inch shank mounted points and rotary files compatible with straight-handle air die grinders operating at 90 psi shop air supply.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of pneumatic tools should be performed by qualified personnel familiar with compressed air safety practices. Before mounting or changing a collet accessory, disconnect the air supply hose completely. Verify the air supply regulator is set to the rated 90 psi and that the inline air line is equipped with a filter-regulator-lubricator to protect the motor. Do not exceed the rated speed of any mounted abrasive accessory installed in the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 0.5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 24000 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: 26 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: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Front\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 51303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNABRADE","offers":[{"title":"Default Title","offer_id":51542144581938,"sku":"51303","price":621.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c381ddf66842ada93b3c7fb91944f034.jpg?v=1785893527","url":"https:\/\/voomisupply.com\/products\/dynabrade-51303-air-die-grinder-0-5-hp-24000-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
