Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and extended wheel life in demanding grinding applications. It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The 100 grit, J hardness (fine grade, medium hardness rating) configuration suits finish and semi-finish grinding passes where surface quality matters. Rated to 3600 RPM, it fits standard surface grinder spindle configurations used in production and tool room environments.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use on CNC cutting tool machines, cylindrical grinders, and surface grinders in both production shop and tool room settings. Material compatibility includes 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is appropriate for applications requiring consistent stock removal on difficult-to-grind materials where a semi-friable ceramic grain is preferred over conventional aluminum oxide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with vitrified bond for consistent cut and long wheel life\u003c\/li\u003e\n\u003cli\u003e100 grit fine grade for finish and semi-finish surface grinding passes\u003c\/li\u003e\n\u003cli\u003eJ hardness code, medium hardness rating, semi-friable grain structure\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel geometry with no recess and no taper\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum rated speed for surface and cylindrical grinder use\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad range of ferrous and high-alloy workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Always inspect the wheel for cracks or chips before mounting and perform a ring test per the wheel manufacturer guidelines. Power down and lock out the grinder before changing wheels. Never exceed the maximum rated RPM of 3600 and ensure the arbor hole fits the spindle without forcing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Flat, No Recess, No Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrain Friability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 5SG100-JVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.58 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66252940204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539247071538,"sku":"66252940204","price":191.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea04236c4cd3e1023c243f8819d96d88.jpg?v=1785837067","url":"https:\/\/voomisupply.com\/products\/norton-66252940204-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
