Part of the R860 series, it features a zirconia alumina abrasive grain with a self-lubricating treatment that promotes cooler cutting and extended disc life. The disc mounts via a Speed-Lok TR Type R attaching system for rapid tool-free changes on compatible handheld disc sanders. At 80 grit (medium-to-coarse grade), it is suited for stock removal, weld blending, and deburring. A heavy Y-weight polyester backing provides rigidity and durability under load. Licensed trades and fabricators use this disc for high-throughput grinding operations where heat buildup and disc wear are primary concerns.\u003c\/p\u003e\n\u003cp\u003eThis disc is rated for use on 300 series stainless steel, 400 series stainless steel, aluminum, brass, bronze, fiberglass and composites, hard and soft carbon steels, and hard and soft woods. Its rigid backing and coarse grit make it well suited to weld blending and deburring on fabricated metal assemblies, as well as surface prep work on structural components. The 1.5-inch diameter fits compact handheld disc sanders used in tight clearance areas common in sheet metal fabrication, HVAC ductwork, and general mechanical trade work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive grain with self-lubricating treatment for faster cuts and reduced heat\u003c\/li\u003e\n  \u003cli\u003e80 grit coarse grade optimized for stock removal, weld blending, and deburring\u003c\/li\u003e\n  \u003cli\u003eSpeed-Lok TR Type R quick-change attaching system for tool-free disc swaps\u003c\/li\u003e\n  \u003cli\u003eHeavy Y-weight polyester backing provides rigidity and resistance to tearing under load\u003c\/li\u003e\n  \u003cli\u003eRated to 30,000 RPM for use with standard handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003e1.5-inch diameter suited for confined-space grinding applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with handheld disc sanders equipped with a Speed-Lok TR Type R quick-change mounting system.

Verify the tool spindle speed does not exceed the 30,000 RPM disc rating before operation. Always inspect the disc for damage or delamination before mounting, and replace any disc showing visible defects. Personal protective equipment including eye protection and gloves should be worn during all grinding operations per applicable safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 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 (Heavy)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Speed-Lok TR Type R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66261121044\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540460667186,"sku":"66261121044","price":115.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e97c759b132823fae11f88d500f927f.jpg?v=1785855878","url":"https:\/\/voomisupply.com\/products\/norton-66261121044-quick-change-disc-80-grit-1-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
