Constructed with aluminum oxide abrasive and a vitrified bond, this wheel measures 12 inches in diameter and 1-1\/2 inches thick with a 5-inch arbor hole. It carries a 46 grit coarse grade with K hardness rating, rated to a maximum of 2070 RPM. A one-side recess with a 7-1\/2-inch recess diameter and 1\/2-inch depth makes it compatible with recessed hub surface grinder setups. The porous, vitrified structure promotes cool cutting and efficient swarf evacuation during heavy stock removal cycles.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders and cylindrical grinders in industrial and job shop environments. Typical applications include rough and semi-finish grinding of 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46 grit formulation is best matched to aggressive stock removal passes rather than finish work, making it a go-to choice when material needs to come off fast before a finishing wheel takes over.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for broad compatibility across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure supports cool cutting and chip clearance\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade designed for high-volume stock removal\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium) balances wheel wear rate with cutting aggression\u003c\/li\u003e\n  \u003cli\u003eOne-side recess (7-1\/2 inches diameter, 1\/2 inch deep) for recessed hub spindle mounting\u003c\/li\u003e\n  \u003cli\u003eSeries designation 32A46-KVBE provides direct spec reference for wheel dressing and selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Machine spindle must be brought to a full stop and locked out before changing wheels. Never exceed the marked maximum operating speed of 2070 RPM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 7-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\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: 2070\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32A46-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.91 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: 66253263170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540990853426,"sku":"66253263170","price":625.84,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/091fc677d410b7670392e0b598261ca2.jpg?v=1785867058","url":"https:\/\/voomisupply.com\/products\/norton-66253263170-type-5-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
