It measures 7 inches in diameter by 1\/4 inch thick with a 1-1\/4 inch arbor hole. The wheel is made from white aluminum oxide abrasive bonded with a vitrified bond, rated at 100 grit for fine-grade stock removal. Its K hardness code places it in the medium hardness range, and the semi-friable grain structure helps the wheel self-dress as it cuts. Maximum operating speed is 3,600 RPM. Machinists, tool grinders, and grinding technicians install and operate this wheel in production and maintenance grinding applications.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is well suited for grinding soft carbon steels, tool steels, and super alloys where a fine surface finish and controlled stock removal are required. The non-porous, vitrified bond construction holds form well under moderate grinding pressure, making it a practical choice for both light finishing passes and moderate material removal on precision workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive for consistent cut on ferrous and alloy workstations\u003c\/li\u003e\n\u003cli\u003eVitrified bond for form stability and easy dressing\u003c\/li\u003e\n\u003cli\u003e100 grit fine grade delivers smooth surface finish with controlled material removal\u003c\/li\u003e\n\u003cli\u003eK hardness (medium) resists glazing while maintaining wheel shape\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain promotes self-sharpening action under load\u003c\/li\u003e\n\u003cli\u003eNon-porous construction suited for dry and wet grinding environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the 3,600 RPM maximum rated speed. Use correct flange hardware and blotters as required by the grinder manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\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: 0.25 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\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\u003eGrit\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\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: 3,600\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\u003eWheel Color\u003c\/strong\u003e: White\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\u003eSpecification Code\u003c\/strong\u003e: 38A100-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.79 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: 66252939827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541357330738,"sku":"66252939827","price":60.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db868e4b5f36d8b5af17f47946f80bdc.jpg?v=1785873412","url":"https:\/\/voomisupply.com\/products\/norton-66252939827-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
