It measures 7 inches in diameter and 1\/4 inch thick, with a 1-1\/4 inch arbor hole. The abrasive is aluminum oxide with a vitrified bond, rated at a medium grade and I hardness code. The semi-friable grain structure at size 6 allows the wheel to fracture and self-dress during operation, maintaining a consistent cut. This wheel is appropriate for grinding ferrous metals and tool steel in machine shop and maintenance environments. Maximum operating speed is 3600 RPM.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is suited for surface grinding applications on horizontal-spindle, reciprocating-table surface grinders commonly found in machine shops, tool rooms, and maintenance facilities. The Type 1 straight-wheel profile fits standard surface grinder spindles with a 1-1\/4 inch bore. The 60-grit, medium-grade specification makes it appropriate for stock removal and general-purpose surface finishing on ferrous workpieces where moderate material removal rates and a reasonably smooth finish are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for effective grinding of ferrous metals and tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity, porosity, and consistent wheel performance\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain fractures progressively to maintain cutting action and reduce glazing\u003c\/li\u003e\n  \u003cli\u003e60 grit, medium grade for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eType 1 straight profile with no recess, fits standard surface grinder arbors\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on horizontal-spindle surface grinders accepting a Type 1 straight wheel with a 1-1\/4 inch arbor bore and a maximum wheel diameter of 7 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel installation and dressing should be performed by a qualified machine operator or maintenance technician following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the rated maximum speed of 3600 RPM and always use the appropriate flange and blotter assembly for proper clamping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess)\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 Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 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\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\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\u003eWheel Color\u003c\/strong\u003e: Pink\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 29A60I6V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: TRU-MAXX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253255633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51755613290802,"sku":"66253255633","price":28.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd73ade85fd0bbdb9ba6dc9e41fa2915.jpg?v=1788956903","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255633-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
