Built around a silicon carbide abrasive grain and bonded with a vitrified bond, this wheel delivers consistent cut rate and wheel form retention throughout its service life. It measures 7 inches in diameter, 3\/4 inches thick, with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3600 RPM. Grit is 100 (Fine grade) with a J hardness code, placing it in the medium-hardness range. Licensed machinists, tool and die shops, and maintenance trades are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding applications in both job shop and production environments. Its silicon carbide abrasive makes it effective on non-ferrous metals and harder-to-grind materials. Compatible machine types listed by the manufacturer include surface grinders, cylindrical grinders, and CNC cutting tool machines. Listed material applications include 300 Series Stainless, Titanium, Aluminum, Brass, Bronze, Copper, Gray Iron, Masonry, and Natural Stone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive grain provides aggressive cut on non-ferrous metals, cast iron, and masonry\u003c\/li\u003e\n  \u003cli\u003eVitrified bond maintains wheel form and allows for dressability during grinding operations\u003c\/li\u003e\n  \u003cli\u003e100 grit, Fine grade for controlled material removal with a smooth finish\u003c\/li\u003e\n  \u003cli\u003eJ hardness (medium) balances wheel wear rate against cut efficiency\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered, no-recess Type 1 straight wheel profile for broad machine compatibility\u003c\/li\u003e\n  \u003cli\u003eGreen wheel color consistent with silicon carbide series identification\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 as stated by the manufacturer.

Always perform a ring test before mounting and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Power down and lock out the grinder before changing wheels. Never use a grinding wheel that has been dropped or shows visible cracking.\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: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 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\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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\u003eManufacturer Specification Code\u003c\/strong\u003e: 39C100-JVMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: 66252942104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538809913650,"sku":"66252942104","price":155.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab778335cf57f473734ac03ed09863b4.jpg?v=1785827159","url":"https:\/\/voomisupply.com\/products\/norton-66252942104-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
