Built with ceramic alumina abrasive on a fabric backing, it delivers fast cut rates and extended disc life compared to conventional aluminum oxide options. The 4.5-inch disc mounts via a 5\/8-11 threaded arbor hole for direct attachment to compatible angle grinders and disc grinders, eliminating the need for a separate backing pad. At 36 grit, this disc is suited for heavy stock removal, weld grinding, and surface preparation work. It is installed and used by metal fabricators, pipefitters, ironworkers, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis fiber disc is intended for use on angle grinders and right-angle grinders equipped with a 5\/8-11 threaded spindle. Typical applications include weld blending, burr removal, edge chamfering, and surface conditioning on ferrous and non-ferrous metals. The coarse 36-grit ceramic alumina construction makes it well suited for high-stock-removal passes where a finer finish is not the immediate goal. The RazorStar series fabric backing provides structural rigidity to resist flexing under load during flat or contoured surface work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic alumina abrasive for fast cut rate and extended service life\u003c\/li\u003e\n  \u003cli\u003e36 grit coarse grade for aggressive stock removal and weld grinding\u003c\/li\u003e\n  \u003cli\u003e4.5-inch diameter with 5\/8-11 threaded arbor hole for direct spindle mount\u003c\/li\u003e\n  \u003cli\u003eFabric backing provides rigidity and resistance to flex under grinding pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eRazorStar series coated abrasive construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders and disc grinders fitted with a 5\/8-11 threaded spindle.

Before mounting, confirm the grinder is unplugged or the battery is removed, and inspect the disc for cracks or damage prior to each use. Always wear appropriate PPE including a face shield, gloves, and hearing protection when operating at grinding speeds. Follow ANSI B7.1 and tool manufacturer guidelines for abrasive wheel mounting and guarding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RazorStar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fabric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Threaded Arbor Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Hole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.068 pounds\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: 25\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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66254430117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540868399410,"sku":"66254430117","price":238.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0553713f8929eba00819481190eaef3f.jpg?v=1785865176","url":"https:\/\/voomisupply.com\/products\/norton-66254430117-fiber-disc-36-grit-4-5-in-ceramic-alumina","provider":"Voomi Supply","version":"1.0","type":"link"}
