Constructed from aluminum oxide abrasive in a vitrified bond matrix, this wheel delivers consistent cut rates and dimensional stability under production grinding conditions. It measures 8 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole. The 100-grit, K-hardness (Medium) specification suits fine-grade finishing work, making it a reliable choice for licensed machinists and tool-and-die professionals operating surface grinders and cylindrical grinders.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on soft carbon steels, tool steels, and super alloys in both production and maintenance grinding environments. Its semi-friable aluminum oxide grain self-sharpens as it wears, maintaining cut efficiency without excessive loading. Typical applications include flat surface grinding, tool reconditioning, and precision profile work on CNC cutting tool machines, cylindrical grinders, and surface grinders. The white wheel color helps operators monitor glazing and loading during use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain structure for consistent self-sharpening action\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and thermal stability during wet or dry grinding\u003c\/li\u003e\n  \u003cli\u003e100 grit, K hardness (Medium) for fine-grade stock removal on precision surfaces\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered, no-recess Type 1 flat wheel configuration\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed rated at 3600 RPM\u003c\/li\u003e\n  \u003cli\u003eSeries specification 38A100-KVBE for direct cross-reference ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuited for use with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the maximum operating speed of 3600 RPM marked on the wheel blotter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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 (Medium)\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\u003eSeries Specification\u003c\/strong\u003e: 38A100-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\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\u003eWeight\u003c\/strong\u003e: 2.09 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: 66253043877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541453668658,"sku":"66253043877","price":99.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de850319025d498db8c4a7dee99fdb2d.jpg?v=1785876531","url":"https:\/\/voomisupply.com\/products\/norton-66253043877-surface-grinding-wheel-8in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
