Measuring 8 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole, this wheel is built around a white aluminum oxide abrasive grain bonded in a vitrified matrix. The 46 grit, H hardness (Coarse grade) combination delivers aggressive cutting action while the semi-friable grain structure supports consistent, cool-running performance. Rated to a maximum of 3,105 RPM, it is sized and rated for surface grinders, cylindrical grinders, and CNC cutting tool machines used in production and toolroom environments.\u003c\/p\u003e\u003cp\u003eThis wheel is well suited for grinding soft carbon steels, tool steels, and super alloys in both job shop and production settings. The 38A Type 1 series is a standard format recognized by tool and cutter grinder operators for its predictable breakdown characteristics and stable vitrified bond, which resists loading and holds form during extended surface grinding passes. Licensed trades and machine operators working in metalworking, toolroom maintenance, and precision grinding will find this wheel appropriate for routine and finish-critical applications alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive for consistent cutting on ferrous metals and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond resists loading and maintains wheel form under heat and pressure\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for efficient stock removal\u003c\/li\u003e\n\u003cli\u003eH hardness code with semi-friable grain for controlled, cool-running grinding\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile fits standard surface grinder and cylindrical grinder spindle setups\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-tapered, no-recess construction for straightforward mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Power down and lock out the machine before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM of 3,105. Use appropriate flanges and blotters as specified by the machine manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 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\u003eWheel Type\u003c\/strong\u003e: Type 1\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\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\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\u003eMaximum RPM\u003c\/strong\u003e: 3,105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 38A46-HVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\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: 2.09 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: 66253043746\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541366866226,"sku":"66253043746","price":95.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f19a9f1f53622496c0ed42f18420fec4.jpg?v=1785873700","url":"https:\/\/voomisupply.com\/products\/norton-66253043746-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
