Powered by compressed air at 90 psi, it delivers up to 20,000 RPM with a 1 hp output, making it suitable for grinding, deburring, and porting operations. The lever throttle gives the operator direct speed control during use. Rear exhaust directs airflow away from the work surface, keeping debris out of the operator's line of sight. Weighing 2.2 pounds, it is compact enough for extended use in confined or overhead applications. Licensed trades and production machinists are the primary installers and operators of this tool.\u003c\/p\u003e\n\u003cp\u003eThe 52669 is designed for use in metalworking, fabrication, automotive, and aerospace finishing applications where a straight-profile die grinder is required. It accepts a 1\/4 inch collet insert (50013) included with the tool. Optional collet inserts expand compatibility to 1\/8 inch (50065), 3\/8 inch (50014), 6 mm (50016), and 8 mm (50039) shank sizes, covering a wide range of rotary burrs, mounted points, and carbide tooling. Typical install scenarios include production floor stations and bench work where a regulated compressed air supply at 90 psi is available.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOperates at 20,000 RPM with a 1 hp air motor for aggressive material removal\u003c\/li\u003e\n  \u003cli\u003eLever throttle provides precise speed and control during operation\u003c\/li\u003e\n  \u003cli\u003eRear exhaust directs spent air away from the workpiece\u003c\/li\u003e\n  \u003cli\u003eIncludes 1\/4 inch collet insert (50013); accepts optional 1\/8 inch, 3\/8 inch, 6 mm, and 8 mm inserts\u003c\/li\u003e\n  \u003cli\u003eLightweight at 2.2 pounds for reduced fatigue in sustained-use applications\u003c\/li\u003e\n  \u003cli\u003eCE Certified and EAC Certified for applicable market compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eAccepts 1\/4 inch collet insert (50013) included.

Before attaching or changing collet inserts or tooling, disconnect the air supply line completely. Verify the shop air supply is regulated to the specified operating pressure before connecting the tool. Follow applicable OSHA standards and manufacturer guidelines for abrasive and rotary tooling speed ratings to ensure the mounted accessory RPM rating meets or exceeds the tool free speed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 20,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed Range\u003c\/strong\u003e: 18,000 - 24,999 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e: 1 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 44 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrottle Type\u003c\/strong\u003e: Lever\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust\u003c\/strong\u003e: Rear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (included)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CE Certified, EAC Certified\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: 52669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNABRADE","offers":[{"title":"Default Title","offer_id":51697656398130,"sku":"52669","price":851.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1fc74436151b3ed35c1d8b5e8bfdd73.jpg?v=1788353838","url":"https:\/\/voomisupply.com\/products\/dynabrade-52669-straight-air-die-grinder-20000-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
