At 60 grit, it sits in the medium-coarse range, making it well suited for aggressive stock removal, weld blending, and surface conditioning on steel and other ferrous metals. The Type 29 conical configuration increases surface contact area compared to a flat Type 27 disc, delivering faster material removal on flat and contoured workpieces. Each disc measures 5 inches in diameter with a 7\/8-inch arbor hole, and weighs approximately 0.26 pounds. Metal fabricators, welders, pipefitters, and general contractors are the primary installers and users of this product.\u003c\/p\u003e\n\u003cp\u003eThe DW8317 is used in metal fabrication shops, construction sites, and maintenance environments where rapid material removal and weld cleanup are required. The 60-grit zirconia abrasive is a strong fit for grinding down weld beads, removing mill scale, and blending seams on structural steel, angle iron, and pipe. The Type 29 raised-hub geometry allows the disc to work efficiently at a slight angle to the workpiece, which reduces operator fatigue during extended use on flat stock or pipe saddles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical flap disc geometry for increased contact and faster stock removal\u003c\/li\u003e\n  \u003cli\u003e60-grit zirconia alumina abrasive for aggressive cutting on ferrous metals\u003c\/li\u003e\n  \u003cli\u003e5-inch diameter with 7\/8-inch arbor fits standard 5-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.26 pounds, reducing fatigue during extended grinding operations\u003c\/li\u003e\n  \u003cli\u003eSuitable for weld blending, deburring, surface conditioning, and scale removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for 5-inch angle grinders accepting a 7\/8-inch arbor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlap discs are installed and operated by metal fabricators, welders, and tradespeople using angle grinders rated for the disc diameter and maximum RPM. Always confirm the grinder speed rating meets or exceeds the disc maximum RPM before mounting. Disconnect power or remove the battery before changing discs, and inspect the disc for damage before each use. Eye protection, a face shield, and appropriate PPE are required per ANSI B7.1 and OSHA grinding safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 29 (Conical)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 028877310510\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: DW8317\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51344981492018,"sku":"DW8317","price":110.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310494785.jpg?v=1782047133","url":"https:\/\/voomisupply.com\/products\/dewalt-dw8317-type-29-zirconia-flap-disc-60-grit-5x7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
