Built from aluminum oxide abrasive with a vitrified bond, this wheel runs at a maximum of 4140 RPM and carries an 80-grit, medium-grade specification suited to controlled material removal. At 6 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole, it mounts directly to standard surface and cylindrical grinders. The series designation 38A80-KVBE identifies the full specification: abrasive type, grit, hardness code K, and bond system. The semi-friable aluminum oxide grain self-sharpens during use, maintaining cut rate without excessive heat buildup on the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on soft carbon steels, tool steels, and super alloys in production and maintenance grinding applications. It fits surface grinders, cylindrical grinders, and CNC cutting tool machines where a Type 1 straight wheel with a vitrified bond is specified. The non-porous, non-tapered, non-recessed profile makes it a straightforward drop-in for machines configured for 6-inch diameter straight wheels. Machinists, tool and die workers, and maintenance technicians working in job shop or production environments will find this wheel applicable to routine sharpening, flat grinding, and tool reconditioning tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond provides consistent, controllable cut on ferrous metals\u003c\/li\u003e\n  \u003cli\u003e80-grit medium grade balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure promotes self-sharpening action during grinding passes\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess and no taper for direct arbor mounting\u003c\/li\u003e\n  \u003cli\u003eRated to 4140 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color aids visual inspection of wheel condition between dressings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum RPM of 4140. Use the correct flanges and blotters as specified by the machine manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 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\u003eMaximum RPM\u003c\/strong\u003e: 4140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 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: 66252835807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540147503410,"sku":"66252835807","price":64.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/658c4978d65e41a77f8e306e5d3e45a9.jpg?v=1785847095","url":"https:\/\/voomisupply.com\/products\/norton-66252835807-surface-grinding-wheel-80-grit-6in","provider":"Voomi Supply","version":"1.0","type":"link"}
