Built with aluminum oxide abrasive in a vitrified bond, this wheel delivers consistent cut rates and predictable wear characteristics. It measures 7 inches in diameter and 1 inch thick, with a 1-1\/4 inch arbor hole and a single-side recess of 3 inches diameter by 0.5 inches deep. The 60 grit, J hardness (medium grade) construction balances aggressive material removal with controlled surface finish. Rated to 3600 RPM maximum, it is suited for both cylindrical and surface grinder applications. The semi-friable grain structure allows for self-dressing behavior under load, maintaining wheel face integrity across extended use cycles.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for grinding soft carbon steels, tool steels, and super alloys on cylindrical grinders and surface grinders. The medium-grade vitrified bond holds the aluminum oxide grain firmly while allowing fracture and exposure of fresh cutting edges as the wheel wears. The porous, white aluminum oxide construction runs cooler than denser bonds, reducing the risk of thermal damage to workpiece surfaces. It is appropriate for both job-shop and production grinding environments where dimensional control and surface quality are required on steel components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 single-side recessed profile with 3 inch recess diameter and 0.5 inch recess depth for clearance on flanged workholding setups\u003c\/li\u003e\n\u003cli\u003e60 grit, J hardness (medium grade) aluminum oxide abrasive for balanced stock removal on steel and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and dimensional stability under grinding pressure\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain fractures controllably, exposing fresh cutting edges and extending wheel life\u003c\/li\u003e\n\u003cli\u003ePorous structure promotes cooler cutting and reduces thermal stress on workpiece surfaces\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum operating speed; wheel color is white for easy identification of aluminum oxide specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with cylindrical grinders and surface grinders requiring a Type 5 recessed wheel with a 1-1\/4 inch arbor hole.

Always perform a ring test before mounting and confirm the spindle speed does not exceed the 3600 RPM maximum marked on the wheel. Power down and lock out the grinder before mounting or removing the wheel. Never exceed the rated RPM, use damaged wheels, or force a wheel onto an arbor that requires excessive pressure to seat.\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 5\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: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\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\u003eRecess Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\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: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003ePorous\u003c\/strong\u003e: Yes\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\u003eManufacturer Specification\u003c\/strong\u003e: 38A60-JVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.93 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: 66252942816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543401365810,"sku":"66252942816","price":99.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2b1b75a1ce7757772bb5756aee4d3b7.jpg?v=1785917967","url":"https:\/\/voomisupply.com\/products\/norton-66252942816-surface-grinding-wheel-60-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
