The wheel measures 10 inches in diameter and 1 inch thick with a 3-inch arbor hole, and it is constructed from white aluminum oxide abrasive bonded in a vitrified matrix. At 46 grit with an I hardness code, this coarse-grade wheel delivers aggressive cutting action while the semi-friable grain structure promotes consistent self-sharpening during the grind cycle. The 38A series specification and non-porous construction make it a reliable choice for high-volume material removal applications in production and toolroom environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production shop and toolroom settings. Its coarse 46 grit rating makes it most effective on softer workpiece materials where high removal rates are the priority. The vitrified bond holds up well under the heat and pressure generated during surface grinding operations, and the medium hardness rating resists premature glazing on the softer steel grades it is designed for. Licensed grinding machine operators and tool and die professionals are the primary installers of this wheel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWhite aluminum oxide abrasive for consistent cut on soft carbon steels, tool steels, and super alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction provides rigidity and stability at rated speeds\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain promotes self-sharpening and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eI hardness code with medium hardness rating resists glazing on softer workpieces\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered, no-recess Type 1 straight wheel geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Always ring-test the wheel before mounting and inspect for cracks or damage. Power down and lock out the grinding machine before changing wheels. Never exceed the maximum rated speed of 2485 RPM; confirm the machine spindle speed before mounting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\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: 2485\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\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: 38A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 38A46-IVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.097 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: 66253160889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540667695410,"sku":"66253160889","price":177.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1d9b80f17adeae3516cff6d63444988.jpg?v=1785861367","url":"https:\/\/voomisupply.com\/products\/norton-66253160889-surface-grinding-wheel-46-grit-10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
