Measuring 5 inches wide, 6 inches high, and 1-1\/2 inches thick and weighing 5 pounds, this segment features a 30-grit, very coarse abrasive structure well suited for aggressive stock removal on ferrous metals. The hardness code F designation and open grain structure (grade 12) promote free cutting and reduce heat buildup during heavy-duty grinding passes. The vitrified bond provides a rigid, porous matrix that maintains form and resists loading. Installation and replacement are handled by qualified grinding machine operators or tool room machinists following machine manufacturer procedures.\u003c\/p\u003e\n\u003cp\u003eThis surface grinding segment is intended for use on reciprocating surface grinders in industrial tool rooms, production grinding operations, and maintenance machine shops. The very coarse 30-grit rating makes it appropriate for rapid material removal rather than finish grinding. Per the supplier specification, this segment is designed for application on Hanchett, Mattison, and Norton surface grinding machines. The open, porous vitrified structure supports consistent cutting action across extended grinding cycles on steel and similar ferrous workpieces.\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 aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with open porous structure reduces loading and heat buildup\u003c\/li\u003e\n  \u003cli\u003eHardness code F promotes free-cutting action during heavy grinding passes\u003c\/li\u003e\n  \u003cli\u003eGrain structure grade 12 supports consistent abrasive exposure throughout segment life\u003c\/li\u003e\n  \u003cli\u003eSpecification code 86A30-F12VBEP for precise cross-reference and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on Hanchett, Mattison, and Norton reciprocating surface grinders per blue print number ME20579 and specification 86A30-F12VBEP.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSurface grinding segments must be installed by trained machine operators or tool room personnel following all applicable machine manufacturer guidelines and ANSI B11.24 safety standards for grinding machines. Always power down and lock out the grinder before removing or mounting segments. Inspect the segment for cracks or chips before installation and never mount a damaged segment. Ensure proper seating and clamping according to the machine manufacturer torque and fitment specifications provided in the machine documentation.\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: F\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-F12VBEP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlue Print Number\u003c\/strong\u003e: ME20579\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: 5 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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61463650273\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542758818098,"sku":"61463650273","price":144.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2409d953ab51b4c3550a79ae99081fe7.jpg?v=1785906492","url":"https:\/\/voomisupply.com\/products\/norton-61463650273-surface-grinding-segment-30-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
