The 5-inch disc features a fiberglass backing and a 7\/8-inch arbor hole, with a maximum operating speed of 12,200 RPM. The 40-grit coarse abrasive cuts fast on welds, scale, and rough stock, making it a go-to choice for metal fabricators, pipefitters, and ironworkers running angle grinders in fabrication shops or field settings. The conical Type 29 profile increases surface contact on flat and contoured workpieces for consistent stock removal.\u003c\/p\u003e\n\u003cp\u003eThe DW8315 is suited for grinding and blending operations on mild steel and stainless steel. The zirconia alumina abrasive self-sharpens during use, maintaining cut rate over the life of the disc. Common applications include weld seam removal, surface prep before coating or welding, and edge cleanup on structural steel. This disc is a standard fit for 5-inch angle grinders used in fabrication, maintenance, and construction trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical profile increases contact area on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive self-sharpens for sustained cut rate\u003c\/li\u003e\n  \u003cli\u003e40-grit coarse grade for fast stock removal and weld grinding\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing provides rigidity and support under load\u003c\/li\u003e\n  \u003cli\u003eRated to 12,200 RPM for use on standard 5-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003eSuitable for both mild steel and stainless steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 5-inch angle grinders with a 7\/8-inch arbor.

Confirm the grinder RPM rating meets or exceeds 12,200 RPM before mounting. Power down and disconnect the grinder from its power source before mounting or removing the disc. Always inspect the disc for cracks or damage before use and follow ANSI B7.1 safety requirements for abrasive wheel mounting and guarding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steels, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 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: DW8315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51699010339122,"sku":"DW8315","price":21.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d22516dab4a48fd9ed9bd4f0312c47d.jpg?v=1788371127","url":"https:\/\/voomisupply.com\/products\/dewalt-dw8315-flap-disc-40-grit-type-29-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
