Built with a ceramic alumina abrasive and a resinoid bond, it delivers consistent stock removal with coarse-grade aggressiveness. The wheel measures 9 inches in diameter and 1\/4 inches thick, with a 7\/8-inch arbor hole for standard spindle fitment. At 1.68 pounds, it is suited for sustained grinding passes on steel, stainless, and other hard metals in fabrication and maintenance environments. The rigid, non-flexible construction holds geometry under load for flat and edge grinding applications.\u003c\/p\u003e\u003cp\u003eThis wheel is used in structural steel fabrication shops, pipeline work, maintenance and repair operations, and heavy manufacturing where aggressive surface grinding or weld blending is required. The Type 27 raised-hub profile allows grinding at lower angles, reducing operator fatigue during extended flat-surface or bevel-grinding tasks. It fits 9-inch angle grinders accepting a 7\/8-inch arbor. The coarse ceramic alumina grain is well matched to ferrous metals and heat-resistant alloys where faster cut rates are prioritized over fine finish.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 depressed-center profile for low-angle flat and bevel grinding\u003c\/li\u003e\n\u003cli\u003eCeramic alumina abrasive for aggressive, consistent stock removal\u003c\/li\u003e\n\u003cli\u003eCoarse grade delivers fast cut rates on ferrous and heat-resistant alloys\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides durability and resistance to shattering under load\u003c\/li\u003e\n\u003cli\u003eRigid, non-flexible construction maintains wheel geometry during heavy passes\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits standard 9-inch angle grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 9-inch angle grinders and right-angle grinders equipped with a 7\/8-inch arbor spindle.

Always power down and disconnect or lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never mount a damaged wheel. Use the correct flange size and tighten the arbor nut to the tool manufacturer's specified method — do not overtighten by impact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27\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: 0.25 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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66253370802\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540325400882,"sku":"66253370802","price":40.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/998612299fa79663d784cee6cac1f2fa.jpg?v=1785852234","url":"https:\/\/voomisupply.com\/products\/norton-66253370802-type-27-grinding-wheel-9in-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
