Built on a vitrified bond with silicon carbide abrasive, this 4-inch diameter, 1\/2-inch thick wheel runs at a rated maximum of 8120 RPM. The 60-grit, medium-grade construction delivers aggressive cutting action while maintaining consistent wheel integrity during extended machine cycles. At 0.45 pounds, it is compact enough for ID grinder and surface grinder spindles used in tool rooms, machine shops, and maintenance environments. The 37C series designation indicates a silicon carbide formulation suited for materials that load conventional aluminum oxide wheels.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. It is intended for installation on CNC cutting tool machines, cylindrical grinders, ID grinders, and surface grinders. The 1\/2-inch arbor hole fits standard spindle configurations common to bench-mounted and machine-mounted grinders in light industrial and trade shop settings. Machinists, tool and die technicians, and maintenance mechanics are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide abrasive, 37C series — optimized for non-ferrous metals, stainless, and masonry\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides dimensional stability and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e60-grit medium grade for efficient material removal without excessive surface heat\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile, no recess, non-porous, non-tapered construction\u003c\/li\u003e\n\u003cli\u003eRated to 8120 RPM for safe operation on standard grinder spindles\u003c\/li\u003e\n\u003cli\u003eCompact 4-inch diameter fits ID grinders and surface grinders with limited clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, ID grinders, and surface grinders equipped with a 1\/2-inch arbor.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation — never mount a damaged wheel. Verify the machine spindle speed does not exceed the 8120 RPM maximum rating marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4 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\u003eHole Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium (Hardness Code M)\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: 8120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\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\u003eSeries\u003c\/strong\u003e: 37C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 37C60-MVMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66243529960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541468873010,"sku":"66243529960","price":77.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53ffe0d4f5921275383b7b7749419302.jpg?v=1785877044","url":"https:\/\/voomisupply.com\/products\/norton-66243529960-surface-grinding-wheel-60-grit-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
