The 9-inch diameter and 1\/4-inch thickness make it a heavy-duty choice for surface grinding and weld blending applications. Its ceramic alumina abrasive with a resinoid bond delivers a coarse cut that holds up under sustained pressure. Licensed tradespeople and fabricators working with steel and hard alloys will find this wheel suited for sustained stock-removal work where consistent cut rate matters more than surface finish.\u003c\/p\u003e\u003cp\u003eThis wheel fits standard 7\/8-inch arbor angle grinders and is designed for use on ferrous metals, structural steel, weld seams, and castings in both shop and field settings. It is appropriate for industrial fabrication, construction, and maintenance applications where coarse grinding is the primary task. The rigid, non-flexible construction keeps the wheel stable during aggressive passes on flat and slightly contoured surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 28 depressed center profile for reduced operator fatigue and improved surface contact angle\u003c\/li\u003e\n\u003cli\u003eCeramic alumina abrasive for fast, self-sharpening cuts on hard metals\u003c\/li\u003e\n\u003cli\u003eCoarse grade for maximum stock removal and weld grinding\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides durability under sustained grinding pressure\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n\u003cli\u003eNon-flexible construction for stable, controlled grinding passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on angle grinders with a 7\/8-inch arbor and a spindle speed rating appropriate for a 9-inch Type 28 grinding wheel. Verify that the grinder's maximum RPM rating meets or exceeds the wheel's rated speed before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never operate above the rated RPM marked on the wheel. Use the correct flanges and ensure the arbor nut is properly torqued according to the grinder manufacturer's specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.68 pounds\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: 66253370805\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540961526066,"sku":"66253370805","price":49.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c04d29b60748d1d7b69752b64e0cbfea.jpg?v=1785866470","url":"https:\/\/voomisupply.com\/products\/norton-66253370805-type-28-grinding-wheel-9-in-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
