The conical Type 29 profile presents the abrasive at an angle to the workpiece, concentrating cutting pressure and increasing stock removal rates compared to flat Type 27 discs. Ceramic alumina grain self-sharpens under load, maintaining consistent cut rate and extending disc life in demanding applications. The cotton backing provides flexibility and conformability across weld seams, bevels, and contoured surfaces. Rated at 8,700 RPM maximum, the disc mounts via a 5\/8-11 threaded arbor hole and ships in a quantity of 5 per package.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for coarse-grade grinding and blending operations in metal fabrication, shipbuilding, structural steel erection, and maintenance welding environments. Typical applications include weld bead removal, surface preparation before coating, edge chamfering, and scale removal on carbon steel and stainless steel workpieces. At 40 grit, it removes material quickly without the refinement needed for final finishing passes. It is commonly used by ironworkers, pipefitters, welders, and metal fabricators working with 5-inch to 7-inch right-angle grinders in both shop and field settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic alumina abrasive grain self-sharpens under pressure for sustained cut rate and longer disc life\u003c\/li\u003e\n  \u003cli\u003eType 29 conical profile increases contact angle for higher stock removal on flat and beveled surfaces\u003c\/li\u003e\n  \u003cli\u003e40 grit coarse grade removes weld beads, scale, and base material rapidly\u003c\/li\u003e\n  \u003cli\u003eCotton backing conforms to contoured and irregular workpiece geometry\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor hole mounts directly to standard right-angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003e8,700 RPM maximum speed rating for safe operation on compatible grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on right-angle grinders with a 5\/8-11 threaded spindle accepting a 7-inch disc.

Verify the grinder's no-load RPM rating does not exceed the disc's 8,700 RPM maximum before mounting. Power down and disconnect the grinder from its power source before changing discs. Inspect the disc for cracks or damage before each use and do not use a damaged disc.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Hole Thread Size\u003c\/strong\u003e: 5\/8-11\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: Ceramic Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Threaded Arbor Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cotton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 8,700\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steels, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7 inches L x 7 inches W x 1.12 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\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: DWA8286H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51559383957810,"sku":"DWA8286H","price":111.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb015cf6ff14653cd62bc6f011a79fe3.jpg?v=1786430736","url":"https:\/\/voomisupply.com\/products\/dewalt-dwa8286h-7-inch-flap-disc-40-grit-ceramic-type-29","provider":"Voomi Supply","version":"1.0","type":"link"}
