Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action at a coarse 46 grit. It measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a maximum rated speed of 2,070 RPM. At 9.045 pounds, the wheel suits heavy-duty surface and cylindrical grinding operations performed by machinists and grinding technicians in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its aluminum oxide composition and I-hardness (medium) rating make it well suited for grinding soft carbon steels, tool steels, and super alloys where aggressive material removal is required. The semi-friable abrasive continually fractures to expose fresh cutting edges, maintaining consistent cut rates throughout the wheel life. The white, non-porous, non-tapered Type 1 profile fits standard straight-wheel spindle setups common in both manual and automated grinding cells.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain structure for self-sharpening action\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid, stable cutting with good form-holding\u003c\/li\u003e\n  \u003cli\u003eCoarse 46 grit rated for aggressive stock removal on soft carbon steels, tool steels, and super alloys\u003c\/li\u003e\n  \u003cli\u003eI hardness (medium) resists glazing while maintaining wheel shape under load\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered, no-recess Type 1 profile for straightforward spindle mounting\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 2,070 RPM — do not exceed\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.

Always power down and de-energize the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and verify that the machine spindle speed does not exceed the 2,070 RPM maximum rating marked on the wheel. Use proper flanges and blotters as required; never force the wheel onto an undersized or damaged arbor.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,070\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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: 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\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 38A46-IVBE\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\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\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.045 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253262702\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542439952690,"sku":"66253262702","price":203.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02b65996b161fbcd2cad8cfcb6ef9d7b.jpg?v=1785900575","url":"https:\/\/voomisupply.com\/products\/norton-66253262702-surface-grinding-wheel-46-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
