Built with white aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and thermal stability throughout the grind. At 46 grit with an H hardness code (coarse grade, soft wheel hardness rating), it removes material aggressively while remaining semi-friable to resist loading. Rated to 3600 RPM, it is suitable for both wet and dry operation. Weighing 1.5 pounds, the wheel is straightforward to mount and balance for standard surface grinding setups.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The 38A Type 1 series is a widely used specification in tool rooms and production grinding operations where consistent aluminum oxide performance is required on ferrous workpieces. The porous structure promotes coolant flow and chip clearance, making it well-suited for applications where heat management at the workpiece is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWhite aluminum oxide abrasive for consistent, repeatable cutting on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and thermal stability during grinding\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eH hardness code (soft wheel hardness) reduces glazing on softer workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePorous structure supports wet and dry operation with effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNo recess, no taper — standard Type 1 straight wheel geometry\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 ring-test the wheel before mounting and ensure the machine spindle speed does not exceed the 3600 RPM rating stamped on the wheel. Use proper blotters and flanges rated for the wheel diameter, and dress the wheel after mounting before taking the first cut. Power down and lock out the grinder before changing wheels.\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: 0.5 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\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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 38A46-HVP2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\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: 66252916223\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540346863922,"sku":"66252916223","price":78.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97f1f8f48f2d69c19d0e1d064ab8ae72.jpg?v=1785852867","url":"https:\/\/voomisupply.com\/products\/norton-66252916223-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
