Measuring 4.5 inches in diameter by 0.25 inches thick with a 5\/8-11 arbor thread, this wheel mounts directly to standard right-angle grinders used across fabrication and construction trades. Zirconia alumina abrasive grain cuts faster and runs cooler than standard aluminum oxide, making it suitable for extended grinding sessions on ferrous metals, weld removal, and surface conditioning work. At 0.46 pounds, the wheel is light enough to keep tool fatigue manageable during overhead or vertical grinding tasks.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is suited for metal fabrication shops, structural steel contractors, pipefitters, plumbers, and general contractors who need consistent stock removal on mild steel, stainless steel, and other ferrous materials. The 4.5-inch diameter fits the most common class of angle grinders found on job sites and in trade shops, and the 5\/8-11 threaded arbor is the industry-standard mounting interface for that tool class. It is sold individually and is appropriate for both bench work and field grinding applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZirconia alumina abrasive grain for faster cut rate and extended wheel life versus standard aluminum oxide\u003c\/li\u003e\n\u003cli\u003e4.5-inch diameter fits standard compact angle grinders with 5\/8-11 arbor\u003c\/li\u003e\n\u003cli\u003e0.25-inch thickness provides a stable grinding profile for weld grinding and surface prep\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded arbor — the industry-standard interface for 4.5-inch angle grinders\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.46 pounds, reducing tool-end fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-mount replacement or consumable grinding wheel for 4.5-inch angle grinders equipped with a 5\/8-11 threaded spindle, which is the standard arbor size for this class of grinder across major tool brands.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and wheel changes must be performed by a qualified operator following ANSI B7.1 safe use standards for abrasive wheels. Always power down and unplug or de-energize the angle grinder before mounting or removing a grinding wheel. Inspect the wheel for cracks or damage before each use and never operate above the maximum RPM rating marked on the wheel. Ensure the guard is properly positioned before starting the grinder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Zirconia Alumina Bonded Abrasive\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\u003eArbor Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 028877441917\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: DW8809\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51347019268402,"sku":"DW8809","price":87.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310494820.jpg?v=1782096702","url":"https:\/\/voomisupply.com\/products\/dewalt-dw8809-zirconia-grinding-wheel-4-5x0-25-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
