Part of the R860 series, this disc uses a zirconia alumina abrasive grain on a heavy Y-weight polyester backing, delivering a rigid, durable platform that holds up under sustained grinding pressure. The 24-grit extra-coarse grade cuts fast and generates less heat than conventional abrasives, making it well-suited for weld blending, deburring, and material removal on metals and composites. Maximum rated speed is 30,000 RPM. It attaches via the Speed-Lok TR (Type III) quick-change system and is compatible with Type R backing pads used on handheld disc sanders.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for use on a broad range of materials including 300 and 400 series stainless steel, aluminum, brass, bronze, fiberglass and composites, hard and soft carbon steels, and hard and soft woods. The coarse grit makes it a practical choice for fabrication shops, metal finishing operations, and structural weld cleanup where fast, controlled material removal is the priority. It is sized at 2 inches in diameter and is designed for use with handheld disc sanders in production or field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-grit extra-coarse zirconia alumina abrasive for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eHeavy Y-weight polyester backing provides rigidity and durability under load\u003c\/li\u003e\n  \u003cli\u003eSpeed-Lok TR (Type III) quick-change attachment for fast pad swaps\u003c\/li\u003e\n  \u003cli\u003eRated to 30,000 RPM for compatibility with high-speed handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003eSelf-lubricating treatment reduces heat buildup and extends disc life\u003c\/li\u003e\n  \u003cli\u003eSuitable for stainless steel, aluminum, carbon steels, brass, bronze, fiberglass, and wood\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Type R (TR, Type III) quick-change backing pads used on handheld disc sanders.

Confirm the backing pad and spindle are in good condition and rated to handle at least 30,000 RPM before mounting. Power down and disconnect the sander from its power source before changing discs. Operate within the disc's rated RPM and use appropriate PPE including eye protection and gloves during grinding operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: Y-weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\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\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R860\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Handheld Disc Sander\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261138672\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538874335538,"sku":"66261138672","price":62.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d375f85ecf472fcfb8dd04aae46a23f4.jpg?v=1785828662","url":"https:\/\/voomisupply.com\/products\/norton-66261138672-quick-change-disc-2in-24-grit-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
