The disc measures 7 inches in diameter with a 7\/8 inch arbor hole and carries a 36-grit very coarse abrasive rating, making it well suited for weld blending, deburring, and stock removal where surface finish is secondary to cut rate. The conical Type 29 profile presents the abrasive at an angle that concentrates grinding pressure and increases cutting efficiency compared to a flat Type 27 configuration. Maximum rated speed is 8,600 RPM. The abrasive flaps are backed by a poly-cotton material that provides flexibility and consistent grit exposure throughout the disc life.\u003c\/p\u003e\n\u003cp\u003eThis disc is a practical choice for fabrication shops, structural steel contractors, pipeline crews, and maintenance trades working with mild steel, carbon steel, and stainless steel. The GP-Z series zirconia alumina grain self-sharpens under pressure, sustaining cut rate longer than standard aluminum oxide on harder metals. It is appropriate for use on angle grinders in both production and field environments. The very coarse 36-grit designation suits initial pass work such as removing mill scale, grinding welds flush, and cleaning corroded base metal before coating or weld preparation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical profile concentrates grinding pressure for faster stock removal on contoured and flat surfaces\u003c\/li\u003e\n  \u003cli\u003e36-grit very coarse zirconia alumina grain for aggressive cut rate on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eSelf-sharpening zirconia grain maintains consistent cutting performance through the disc life\u003c\/li\u003e\n  \u003cli\u003ePoly-cotton backing provides flap flexibility and even abrasive wear\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003e8,600 RPM maximum speed rating suits common 7-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on angle grinders accepting a 7-inch disc with a 7\/8 inch arbor hole.

Verify the grinder speed rating meets or does not exceed the 8,600 RPM maximum disc rating before mounting. Inspect the disc for cracks or damage before each use and do not use a disc that shows any visible defect. Appropriate eye protection, face shield, and gloves are required; follow ANSI B7.1 and applicable shop safety standards when operating abrasive wheels.\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 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: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very 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: 8,600\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: 0.48 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: 66254443428\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51731598639410,"sku":"66254443428","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20ad7e259af2f28c4cc9066968c4c39f.jpg?v=1788733026","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66254443428-flap-disc-36-grit-type-29-7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
