It measures 4.5 inches in diameter and 0.25 inches thick, with a 7\/8-inch arbor hole for standard angle grinder compatibility. The ceramic abrasive grain at 24 grit cuts fast and runs cool, making it well suited for heavy grinding passes where material removal rate matters. A resinoid bond holds the ceramic grain under load, and the reinforced fiberglass construction supports safe operation up to 13,300 RPM. The wheel weighs 0.42 pounds and ships individually.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used by welders, fabricators, ironworkers, and HVAC sheet metal mechanics for weld grinding, surface prep, and edge cleanup on steel, stainless, and other hard metals. The Type 27 depressed-center profile keeps the grinding face off the workpiece and allows for a low angle of attack, which is the standard configuration for flat surface and weld bead grinding with a 4.5-inch right-angle grinder. The 24-grit ceramic grain suits initial passes and fast stock removal rather than finishing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-grit ceramic abrasive for fast, aggressive grinding action\u003c\/li\u003e\n  \u003cli\u003eType 27 depressed center profile for low-angle flat and weld grinding\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM maximum rated speed for 4.5-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch arbor hole fits standard right-angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003eResinoid bond with reinforced fiberglass construction for durability under load\u003c\/li\u003e\n  \u003cli\u003eHardness code R for consistent performance across the wheel life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for 4.5-inch right-angle grinders accepting a 7\/8-inch arbor and rated to 13,300 RPM or higher.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheels must be installed by qualified personnel following ANSI B7.1 safety standards and the grinder manufacturer guidelines. Always inspect the wheel for cracks or chips before mounting and confirm the grinder spindle RPM rating meets or exceeds 13,300 RPM before use. Power down and unplug or lock out the grinder before changing wheels. Use the correct flange and arbor nut torque per the grinder manufacturer specification, and always run a new wheel for at least 60 seconds at full speed in a guarded area before contact grinding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27 Depressed Center\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4.5 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: 0.875 inches (7\/8 arbor)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReinforced\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\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: DEWALT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DWA8908F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51563787256114,"sku":"DWA8908F","price":21.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6337c2df09fb7d35e2b45d79020136f.jpg?v=1786503524","url":"https:\/\/voomisupply.com\/products\/dewalt-dwa8908f-type-27-grinding-wheel-4-5in-24-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
