The 4-inch disc features a 5\/8-inch arbor hole and a coarse 40-grit abrasive surface rated to 15,300 RPM. Zirconia alumina grain self-sharpens during use, maintaining cut rate longer than standard aluminum oxide. The poly-cotton backing provides flexibility that conforms to contoured workpiece surfaces. This disc is a standard tool for metal fabrication, weld blending, and surface conditioning tasks performed by welders, pipefitters, ironworkers, and general metal tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe 66254443410 is suited for use on mild steel, carbon steel, and stainless steel in both shop and field environments. Its Type 29 conical geometry presents the abrasive at an angle that increases contact area and grinding efficiency on flat and slightly curved surfaces. The coarse 40-grit designation makes it appropriate for initial material removal and weld seam blending rather than finishing passes. Single-disc packaging allows jobsite restocking in exact quantities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina grain self-sharpens under pressure for consistent cut rate throughout disc life\u003c\/li\u003e\n  \u003cli\u003eType 29 conical profile increases abrasive contact area on flat and contoured workpieces\u003c\/li\u003e\n  \u003cli\u003e40-grit coarse grade suited for aggressive stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003ePoly-cotton backing adds flexibility for work on curved or irregular surfaces\u003c\/li\u003e\n  \u003cli\u003e15,300 RPM maximum speed rating compatible with standard 4-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch arbor hole fits common angle grinder spindle sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4-inch angle grinders accepting a 5\/8-inch arbor hole.

Ensure the angle grinder is unplugged or its power source is locked out before mounting or removing the disc. Verify the grinder spindle speed does not exceed the 15,300 RPM disc rating before operation. Always use the appropriate guard and personal protective equipment including eye and face protection when operating grinding equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 5\/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: Poly-Cotton\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: 15,300\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\u003eSeries\u003c\/strong\u003e: GP-Z\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.165 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: TRU-MAXX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66254443410\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51730647482674,"sku":"66254443410","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a81d749413178f9223e72bb240f155ff.jpg?v=1788720808","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66254443410-flap-disc-40-grit-type-29-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
