Built on an aluminum oxide abrasive with a vitrified bond, it delivers consistent cut rates and predictable wear across extended runs. The wheel measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and is rated to 3600 RPM. H hardness and medium grade make this wheel suitable for controlled material removal without excessive loading or glazing. It carries the 38A60-HVBE specification designation used by toolroom and production grinding professionals.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. Material applications include soft carbon steels, tool steels, and super alloys. The semi-friable aluminum oxide grain continuously fractures under load to expose fresh cutting edges, maintaining aggressiveness throughout the wheel life. The white, non-porous, non-tapered Type 1 form fits standard surface grinder spindles and is a common choice in toolroom environments where dimensional accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess — straightforward mounting on surface and cylindrical grinders\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive, semi-friable grade — self-sharpening under load for consistent cut\u003c\/li\u003e\n\u003cli\u003eVitrified bond — open structure promotes coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003eH hardness, medium grade — balances wheel life against material removal rate on steels and super alloys\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum speed rating — confirm machine RPM before mounting\u003c\/li\u003e\n\u003cli\u003e38A60-HVBE specification — recognized series designation for toolroom traceability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Power down and lock out the grinder before mounting or removing any wheel. Perform a ring test before installation to check for cracks — do not mount a wheel that fails the ring test. Never exceed the 3600 RPM maximum speed marked on the wheel, and always use proper flanges and blotters of the correct diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\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\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\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 38A60-HVBE\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66253043756\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543395926322,"sku":"66253043756","price":79.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc5a2641bd0408fd262196e4bda92326.jpg?v=1785917862","url":"https:\/\/voomisupply.com\/products\/norton-66253043756-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
