Built from white aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent, controllable cut rates on a range of metallic workpiece materials. It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and carries a 60 grit, K hardness (medium grade) rating. The semi-friable aluminum oxide grain self-sharpens under load, helping maintain cut efficiency between dressing cycles. Maximum operating speed is rated at 3600 RPM.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding applications in job shop, tool room, and CNC machining environments. It is appropriate for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Recommended material applications include soft carbon steels, tool steels, and super alloys. The medium grade and 60 grit combination makes it a practical choice for intermediate material removal where surface finish control is also a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive grain for controlled cutting action on steels and alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent wheel form retention\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure promotes self-sharpening during grinding\u003c\/li\u003e\n\u003cli\u003e60 grit medium hardness (K) rating balances stock removal with surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess, compatible with standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always ring-test the wheel for cracks before mounting and never exceed the rated maximum RPM of 3600. Power down and lock out the grinder before changing wheels. Use the correct flange size and blotters as specified by the machine manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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: 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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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-KVBE\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253043861\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541918023986,"sku":"66253043861","price":99.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f32841b3ea6e3cb7dea1606d0349a2a.jpg?v=1785887768","url":"https:\/\/voomisupply.com\/products\/norton-66253043861-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
