Powered by compressed air at 90 psi and consuming 26 CFM, it delivers 1.3 horsepower and spins a 7-inch disc at up to 6,000 RPM. The side exhaust directs air away from the work surface and operator. It accepts a 1\/4-inch NPT air inlet, making it compatible with standard shop air lines. The unit ships with a 51151 backing pad and flange included. Metalworkers, fabricators, and finishing trades use this sander for production and maintenance work.\u003c\/p\u003e\n\u003cp\u003eThe 52657 is suited for industrial and manufacturing environments where a right-angle or straight-body disc sander is needed for weld blending, rust removal, paint stripping, or surface conditioning. Its 7-inch pad size handles a wide range of abrasive discs available in that diameter. At 7.9 pounds, it is compact enough for extended handheld use on flat panels, structural steel, and fabricated assemblies. Typical installation scenarios include metal fabrication shops, shipyards, automotive body work, and general maintenance facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6,000 RPM free speed for aggressive stock removal and surface prep\u003c\/li\u003e\n  \u003cli\u003e1.3 HP pneumatic motor runs on standard 90 psi shop air supply\u003c\/li\u003e\n  \u003cli\u003e7-inch disc capacity fits widely available abrasive disc inventory\u003c\/li\u003e\n  \u003cli\u003eSide exhaust keeps debris and air directed away from the work zone\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch air inlet connects to standard shop air fittings without adapters\u003c\/li\u003e\n  \u003cli\u003eShips with 51151 backing pad and flange included — ready to mount a disc\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 7-inch diameter abrasive discs.

Before mounting or changing an abrasive disc, disconnect the air supply line completely. Verify shop air pressure does not exceed the rated 90 psi operating pressure, and ensure the air line delivers adequate CFM to sustain 26 CFM tool demand. Always confirm the abrasive disc is rated at or above the tool free speed before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Size\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 6,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 1.3 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 26 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: 90 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Inlet Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Size\u003c\/strong\u003e: 7 inches (180 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 51151 Backing Pad 7 inches (178 mm) Diameter, Flange\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: 52657\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNABRADE","offers":[{"title":"Default Title","offer_id":51544550965554,"sku":"52657","price":1216.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/510bd168e2efdc115f3c124bec9c168b.jpg?v=1785929619","url":"https:\/\/voomisupply.com\/products\/dynabrade-52657-air-handheld-disc-sander-1-3-hp-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
