It accepts a 3-inch wheel diameter and spins at 18,000 RPM, making it well suited for aggressive material removal and detail work in tight spaces. The tool draws 41 CFM at 90 psi operating pressure and delivers 0.70 HP through a 3\/8-24 spindle. A rear exhaust directs airflow away from the work surface. Weighing 3.4 pounds, it is designed for extended use without significant operator fatigue. Installation and operation are handled by machinists, fabricators, and maintenance technicians working with pneumatic tool systems.\u003c\/p\u003e\u003cp\u003eThis angle grinder is built for industrial and manufacturing environments where consistent, high-speed material removal is required. It connects to a compressed air supply via a 1\/4-inch NPT inlet, making it compatible with standard shop air lines. The triggerlock feature allows sustained operation during extended grinding passes without continuous trigger pressure. Typical applications include weld seam grinding, casting cleanup, and edge preparation on ferrous and non-ferrous metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18,000 RPM free speed for aggressive stock removal on 3-inch abrasive wheels\u003c\/li\u003e\n\u003cli\u003e0.70 HP pneumatic motor delivers consistent power at 90 psi operating pressure\u003c\/li\u003e\n\u003cli\u003e3\/8-24 spindle thread accepts standard 3-inch grinding wheels and accessories\u003c\/li\u003e\n\u003cli\u003eRear exhaust directs air away from the operator and work surface\u003c\/li\u003e\n\u003cli\u003eTriggerlock for sustained operation during extended grinding tasks\u003c\/li\u003e\n\u003cli\u003e1\/4-inch NPT air inlet integrates with standard shop air systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3-inch diameter grinding wheels and accessories with a 3\/8-24 spindle thread, connected to a compressed air supply delivering 90 psi at 41 CFM minimum through a 1\/4-inch NPT fitting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and serviced by qualified machinists or pneumatic tool technicians. Before connecting or disconnecting the air supply, depressurize the line and verify the inlet fitting matches the 1\/4-inch NPT port. Ensure the compressed air supply meets the required 90 psi and 41 CFM flow rate before operation. Always mount the grinding wheel according to the wheel manufacturer's specifications and inspect for cracks or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 18,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 0.70 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 41 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Inlet Size\u003c\/strong\u003e: 1\/4 inches NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriggerlock\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.4 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: 54769\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNABRADE","offers":[{"title":"Default Title","offer_id":51542954574130,"sku":"54769","price":1457.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2c0c1bdc4cf3e94a38bc8b4fa390217.jpg?v=1785912074","url":"https:\/\/voomisupply.com\/products\/dynabrade-54769-air-angle-grinder-3-in-18000-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
