The segment measures 5 inches wide, 6 inches high, and 1-1\/2 inches thick. It is bonded with a vitrified bond and features an open, porous grain structure rated at structure 12, which promotes chip clearance and reduces heat buildup during heavy stock removal. At 30 grit with a G hardness rating, this segment is classified as very coarse and is suited for aggressive material removal passes rather than fine finishing work.\u003c\/p\u003e\n\u003cp\u003eThis segment is intended for use on horizontal-spindle, reciprocating or rotary surface grinders commonly found in production shops and tool rooms. It is listed for use on Hanchett, Mattison, and Norton grinding machines, making it a direct fit for those platforms. The ceramic abrasive grain is engineered to fracture and self-sharpen during operation, sustaining cutting efficiency through extended grinding cycles. This type of segment is typically installed in sets of multiple units to complete a full grinding wheel assembly on segmented-wheel machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with self-sharpening fracture characteristics for sustained cut rate\u003c\/li\u003e\n  \u003cli\u003e30 grit, very coarse grade — optimized for high stock removal applications\u003c\/li\u003e\n  \u003cli\u003eG hardness code, indicating a relatively soft bond that releases dull grains readily\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity, porosity, and resistance to heat and coolant\u003c\/li\u003e\n  \u003cli\u003eOpen grain structure (structure 12) aids chip clearance and reduces grinding heat\u003c\/li\u003e\n  \u003cli\u003eCompatible with Hanchett, Mattison, and Norton surface grinder platforms per blueprint ME20579\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eListed for use on Hanchett, Mattison, and Norton surface grinding machines per Blue Print Number ME20579.

Always de-energize and lock out the grinding machine before removing or installing segments. Inspect each segment for cracks or chips before mounting — never install a damaged segment. Segments must be properly seated and torqued in accordance with machine manufacturer specifications, and the assembled wheel should be dressed before first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\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\u003eBlue Print Number\u003c\/strong\u003e: ME20579\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 8\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: 61463604490\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544073634098,"sku":"61463604490","price":1895.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df46da0c8a58eb912f96a9bb8706b3f6.jpg?v=1785923701","url":"https:\/\/voomisupply.com\/products\/norton-61463604490-surface-grinding-segment-30-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
