The conical T29 profile increases the contact angle between the disc and the workpiece, making it well suited for work on flat surfaces and moderate contours. At 80 grit, it removes material efficiently while leaving a finish suitable for follow-up with a finer abrasive. The 4.5-inch diameter disc mounts via a 5\/8 inches-11 threaded hub and is sold individually. Fabricators, welders, pipefitters, and ironworkers reach for this disc when they need consistent cut rate and long abrasive life from a standard angle grinder.\u003c\/p\u003e\u003cp\u003eThis flap disc is intended for use on carbon steel, stainless steel, and other ferrous metals in fabrication shops, structural steel work, and field welding applications. The 80-grit zirconia construction handles weld seam blending, surface prep before coating, and light stock removal. It fits standard 4.5-inch angle grinders with a 5\/8 inches-11 arbor, which covers the majority of professional-grade grinders used in trades and fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical flap disc profile for increased contact angle on flat surfaces\u003c\/li\u003e\n\u003cli\u003e80 grit zirconia alumina abrasive for aggressive stock removal with a blendable finish\u003c\/li\u003e\n\u003cli\u003e4.5-inch diameter with 5\/8 inches-11 threaded hub fits most professional angle grinders\u003c\/li\u003e\n\u003cli\u003eZirconia grain self-sharpens during use, extending disc life compared to aluminum oxide\u003c\/li\u003e\n\u003cli\u003eSuitable for weld blending, surface preparation, and light grinding on ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment flap disc for 4.5-inch angle grinders equipped with a 5\/8 inches-11 threaded spindle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes must be performed with the grinder unplugged or the battery pack removed. Confirm the grinder spindle speed rating meets or exceeds the maximum RPM marked on the disc before mounting. Use the correct flange and locking nut for the 5\/8 inches-11 arbor and tighten securely before operation. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or missing flaps.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 5\/8 inches-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 29 (T29)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 028877310497\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: DW8313\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51344120742194,"sku":"DW8313","price":55.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310493958.jpg?v=1782029859","url":"https:\/\/voomisupply.com\/products\/dewalt-dw8313-type-29-zirconia-flap-disc-4-5in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
