The disc measures 3 inches in diameter and carries a 320-grit aluminum oxide abrasive, placing it in the extra fine grade category. It is built on a rigid Y-weight 2-ply polyester backing, which adds structural durability and supports a faster cut rate compared to lighter backings. Rated to 20,000 RPM, this disc suits high-speed finishing and detail work on metal surfaces. Licensed HVAC, industrial, and metalworking professionals install and use this disc for deburring, cleaning, and surface detailing.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for work on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The aluminum oxide abrasive compound provides consistent cutting action across these materials. The extra fine 320-grit rating makes it most appropriate for final-pass deburring, light cleaning, and surface detailing rather than aggressive stock removal. It attaches via a Type R attaching system and is compatible with handheld disc sanders accepting TR (Type III) quick-change fittings. Sold individually with a minimum order quantity of 50 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320-grit aluminum oxide abrasive rated extra fine for finish deburring and detailing\u003c\/li\u003e\n  \u003cli\u003eY-weight 2-ply polyester backing provides rigidity and extended disc life\u003c\/li\u003e\n  \u003cli\u003ePower-Lock Type 3 (TR\/Type III) quick-change compatibility with Type R attaching system\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM for use with high-speed handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003eCompatible material applications include stainless steel, brass, bronze, soft and hard carbon steels, and titanium\u003c\/li\u003e\n  \u003cli\u003eBrown disc color, black button; Series R766\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with handheld disc sanders using TR (Type III) quick-change fittings and Type R attaching systems.

Confirm the sander spindle accepts the Type R attaching system before mounting the disc. Always verify the tool RPM rating does not exceed the disc maximum of 20,000 RPM before operation. Inspect the disc for damage before each use and replace if any delamination or wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester (Y-weight 2-ply)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: Y\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: TR (Type III)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R766\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Handheld Disc Sander\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Applications\u003c\/strong\u003e: 300 Series Stainless, Brass, Bronze, Hard Carbon Steels, Soft Carbon Steels, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\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: MERIT ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69957399728\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51559878983986,"sku":"69957399728","price":6351.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c0051f8ec1d07c4e2b5c2f21495e132.jpg?v=1786443361","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69957399728-quick-change-disc-320-grit-3in","provider":"Voomi Supply","version":"1.0","type":"link"}
