Built on a heavy Y-weight polyester backing, this 2-inch disc operates at up to 30,000 RPM and mounts via the Speed-Lok TR (Type III) \/ Type R attaching system. The zirconia alumina abrasive grain runs at 60 grit, placing it in the medium-to-coarse range suited for fast material removal without frequent disc changes. A self-lubricating treatment helps reduce heat buildup during extended grinding sessions, extending disc life and protecting workpiece surfaces.\u003c\/p\u003e\u003cp\u003eThis disc is rated for use on 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, fiberglass and composites, and hard and soft woods. It is part of the R860 series and is intended for use with handheld disc sanders equipped with a Speed-Lok TR or Type R quick-change arbor. The rigid, non-trimmable construction keeps the disc geometry consistent through the full working life of the abrasive. Typical applications include fabrication shops, maintenance and repair operations, and metal finishing work where fast setup and repeatable results matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZirconia alumina grain with self-lubricating treatment for fast cutting and reduced heat\u003c\/li\u003e\n\u003cli\u003eHeavy Y-weight polyester backing for durability under aggressive grinding loads\u003c\/li\u003e\n\u003cli\u003eSpeed-Lok TR (Type III) \/ Type R quick-change mount for tool-free disc swaps\u003c\/li\u003e\n\u003cli\u003eRated to 30,000 RPM for use with standard handheld quick-change disc sanders\u003c\/li\u003e\n\u003cli\u003e60 grit for stock removal, weld blending, and deburring\u003c\/li\u003e\n\u003cli\u003eCompatible with stainless, carbon steel, aluminum, brass, bronze, fiberglass, and wood\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for handheld disc sanders fitted with a Speed-Lok TR (Type III) or Type R quick-change arbor.

Confirm the tool is rated to handle at least 30,000 RPM and power down the tool before changing discs. Inspect the disc for cracks or damage prior to each use and do not exceed the maximum RPM rating marked on the disc. Follow applicable ANSI B7.1 and OSHA grinding safety requirements for abrasive wheel use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium \/ 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\u003eSeries\u003c\/strong\u003e: R860\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: Speed-Lok TR (Type III) \/ Type R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrimmable\u003c\/strong\u003e: No\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\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66261121048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540768489778,"sku":"66261121048","price":51.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e964ee1ce24bddc8b373f97028320bc.jpg?v=1785863747","url":"https:\/\/voomisupply.com\/products\/norton-66261121048-quick-change-disc-2in-60-grit-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
