It measures 8 inches in diameter, 3\/4 inches thick, with a 1-1\/4 inches arbor hole. The wheel is made from aluminum oxide abrasive with a vitrified bond, rated at a coarse 46 grit and K hardness. Grain structure is rated at 6, and the bond specification is 23A46K6V31. The wheel carries a maximum operating speed of 3600 RPM and weighs 3 pounds. It is a non-porous, semi-friable white wheel suited for ferrous metal grinding tasks where consistent stock removal and a controlled finish are required.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in machine shops, maintenance facilities, and tool rooms where surface grinding of steel and other ferrous workpieces is performed. Its coarse 46 grit rating makes it appropriate for aggressive stock removal rather than finish work. The vitrified bond provides rigidity and free-cutting action, and the K medium hardness rating suits a range of general-purpose grinding operations on flat or cylindrical surfaces using bench or pedestal equipment rated for Type 1 wheels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile — compatible with standard bench and pedestal grinders\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive, white, semi-friable for cool, free cutting on steel\u003c\/li\u003e\n  \u003cli\u003eVitrified bond (specification 23A46K6V31) for rigidity and consistent grinding action\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for efficient stock removal\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium) balances wheel life against cut rate\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum operating speed — verify machine speed before mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount replacement for Type 1 straight grinding wheels on bench and pedestal grinders accepting an 8 inches diameter, 3\/4 inches thick wheel with a 1-1\/4 inches arbor hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician following ANSI B7.1 safe-use standards for abrasive wheels. Always disconnect and lock out power to the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before mounting — ring-test per ANSI B7.1 and never use a damaged wheel. Confirm the machine spindle speed does not exceed the 3600 RPM maximum rated speed of this wheel before operation.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46 (Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Specification\u003c\/strong\u003e: 23A46K6V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\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: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: TRU-MAXX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253255854\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51733241528626,"sku":"66253255854","price":57.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2f542f0ab3b07fe6b607a8ea3d0600a.jpg?v=1788753189","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255854-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
