Measuring 5 inches wide, 6 inches high, and 1-1\/2 inches thick, this segment delivers consistent cutting action across its full face. At 30 grit (Very Coarse grade), it is built for aggressive material removal applications where rapid stock reduction takes priority over fine surface finish. The vitrified bond provides an open, porous structure that resists loading and maintains free-cutting performance across extended use cycles. Specification code 86A30-G12VBEP identifies the exact formulation for reorder and cross-reference. Grinding wheel mechanics and abrasive product specialists handle installation and dressing.\u003c\/p\u003e\n\u003cp\u003eThis segment is suited for surface grinding operations in industrial maintenance, tool and die, and production grinding environments. It is designed for use on Hanchett, Mattison, and Norton surface grinders where segments of this profile are the specified consumable. The 30-grit, Very Coarse grade is appropriate for initial passes on castings, hardened steel, and similar ferrous workpieces where heavy stock removal is needed before finish grinding. Blueprint number ME20579 provides the original equipment reference for shops working from machine documentation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive material for reliable performance on ferrous metals\u003c\/li\u003e\n  \u003cli\u003e30 grit, Very Coarse grade for high material removal rates\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction resists loading and maintains open cutting action\u003c\/li\u003e\n  \u003cli\u003ePorous grain structure (grain structure 12) promotes coolant flow and heat dissipation\u003c\/li\u003e\n  \u003cli\u003eHardness Code G provides a relatively soft grade that releases dull grains to expose fresh abrasive\u003c\/li\u003e\n  \u003cli\u003eBlueprint number ME20579 and spec code 86A30-G12VBEP support direct OEM cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on Hanchett, Mattison, and Norton surface grinders that accept segments measuring 5 inches wide, 6 inches high, and 1-1\/2 inches thick, per blueprint ME20579.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSurface grinding segments are installed and replaced by qualified grinding machine operators or maintenance technicians familiar with abrasive product handling standards. Always power down and lock out the grinder before removing or seating segments. Inspect the segment holder and mounting surfaces for damage or debris before installation. Follow the machine manufacturer's torque and seating procedures, and ring-test or visually inspect segments per ANSI B7.1 before placing the machine back in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 86A30-G12VBEP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSegment Width\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSegment Height\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSegment Thickness\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlueprint Number\u003c\/strong\u003e: ME20579\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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61463650275\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540672610610,"sku":"61463650275","price":95.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24c6628a951838c89ed1f9fd0385f13b.jpg?v=1785861527","url":"https:\/\/voomisupply.com\/products\/norton-61463650275-surface-grinding-segment-30-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
