Built around a ceramic abrasive grain with a vitrified bond, this wheel delivers consistent cut rates and long service life under high-cycle production conditions. At 7 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole, it mounts directly to standard surface grinder and cylindrical grinder spindles. The 100-grit, K-hardness (medium) specification produces a fine finish grade suited to finishing passes and close-tolerance work. The porous, semi-friable grain structure promotes cool cutting and reduces heat buildup at the workpiece surface.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines operating in industrial and production shop environments. It is rated for a maximum of 3600 RPM. The 5SG Type 1 series is designed for aggressive material removal on demanding substrates including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Applications range from tool and cutter regrinding to flat surface finishing where dimensional accuracy is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for consistent, controlled cut rate\u003c\/li\u003e\n  \u003cli\u003e100 grit, fine grade for finish-pass surface grinding work\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium) rating balances wheel life against cut aggressiveness\u003c\/li\u003e\n  \u003cli\u003ePorous, semi-friable structure promotes cool cutting and chip clearance\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess, compatible with standard spindle arbors\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always verify the machine's spindle RPM does not exceed the wheel's 3600 RPM maximum before mounting. Inspect the wheel for cracks or chips using a ring test before each use and never mount a damaged wheel. Follow ANSI B11.9 and applicable OSHA standards for abrasive wheel guarding and personal protective equipment during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\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\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: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriable\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\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\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-KVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252939468\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541590573362,"sku":"66252939468","price":173.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae52c9a3a04a9ca35dcf621271f075b8.jpg?v=1785880095","url":"https:\/\/voomisupply.com\/products\/norton-66252939468-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
