It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel is made from aluminum oxide abrasive with a vitrified bond, rated at J hardness with a medium grade and semi-friable grain structure. With a maximum operating speed of 3600 RPM, this wheel is suited for controlled material removal on ferrous metals and tool steels. It weighs 2 pounds and features a white wheel color for easy identification in shop environments.\u003c\/p\u003e\u003cp\u003eThis wheel is used in surface grinding applications on horizontal spindle, reciprocating table surface grinders. It is well suited for tool rooms, machine shops, and maintenance environments where flat stock, tooling, and hardened parts require accurate grinding. The 60 grit provides a moderate stock removal rate while still producing a reasonably smooth finish. Licensed machinists, tool and die makers, and industrial maintenance technicians are the primary installers and operators of this wheel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile — no recess, compatible with standard surface grinder flanges\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive grain — well suited for ferrous metals and general-purpose surface grinding\u003c\/li\u003e\n\u003cli\u003eVitrified bond — offers rigid wheel structure and good form-holding during grinding passes\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure — self-sharpening tendency helps maintain cutting action over the wheel life\u003c\/li\u003e\n\u003cli\u003eJ hardness code, medium grade — balanced wheel hardness for moderate grinding pressure applications\u003c\/li\u003e\n\u003cli\u003eNon-porous construction — consistent grinding performance and structural integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for horizontal spindle surface grinders accepting a 7 inch diameter, 1\/2 inch thick, Type 1 wheel with a 1-1\/4 inch arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting must be performed by a qualified machinist or operator following ANSI B11.22 and OSHA 29 CFR 1910.215 guidelines. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum speed of 3600 RPM. Power down and lock out the surface grinder before removing or installing any wheel. Flanges must be clean, flat, and blotted with compressible paper washers on both sides before tightening the arbor nut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\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: 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\u003eGrain Structure\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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\u003eSpecification Code\u003c\/strong\u003e: 23A60J6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: TRU-MAXX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253255897\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51728215015730,"sku":"66253255897","price":77.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2f58b119d10029ead8e073714aa1d34.jpg?v=1788689681","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255897-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
