Built on a vitrified bond with aluminum oxide abrasive, it delivers consistent cutting action and good form retention across multiple passes. The wheel measures 8 inches in diameter and 1\/4 inches thick, with a 1-1\/4 inches arbor hole for standard spindle mounting. Rated at a maximum of 3600 RPM and spec-coded 38A80-KVBE, this wheel is suited for installation by machinists and grinding technicians working with surface grinders and cylindrical grinders in production and tool-room environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is appropriate for surface grinding applications in both job-shop and production settings. Its medium grade and K hardness code make it effective on softer ferrous materials where wheel breakdown rate needs to match workpiece hardness. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The non-porous, semi-friable aluminum oxide grain continuously self-sharpens under load, helping maintain cutting efficiency over the wheel's service life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain for consistent self-sharpening action\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid form holding and efficient coolant flow\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade suited for stock removal on soft carbon steels and tool steels\u003c\/li\u003e\n  \u003cli\u003eK hardness code balances wheel life and cutting aggressiveness\u003c\/li\u003e\n  \u003cli\u003eNon-tapered, no-recess Type 1 flat wheel geometry for standard surface and cylindrical grinding setups\u003c\/li\u003e\n  \u003cli\u003eMaximum spindle speed rating of 3600 RPM\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.

Before mounting, inspect the wheel for cracks or chips using a ring test per ANSI B7.1 guidelines, and never exceed the marked maximum RPM of 3600. Ensure the machine spindle is fully stopped and locked out before changing wheels. Use proper flanges and a compressible blotter between the flanges and wheel faces to distribute clamping load evenly.\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\u003eSpecification Code\u003c\/strong\u003e: 38A80-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\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: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\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: 1.05 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: 66253043461\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542122627378,"sku":"66253043461","price":82.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/435f79ebc17fcdc7f75324d0598686e2.jpg?v=1785892736","url":"https:\/\/voomisupply.com\/products\/norton-66253043461-surface-grinding-wheel-80-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
