Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and good wheel integrity under sustained grinding pressure. At 10 inches in diameter with a 3\/4-inch thickness and a 3-inch arbor hole, this wheel fits standard surface grinder spindles used in machine shops and tool rooms. The 60 grit, J hardness (medium grade) combination suits general-purpose surface grinding where moderate material removal and a reasonably smooth finish are both required. Maximum rated speed is 3,250 RPM. Weight is 4 pounds.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding applications in machine shops, tool and die operations, and production grinding environments. The aluminum oxide grain with semi-friable characteristics makes it effective on carbon steels, alloy steels, and similar ferrous workpieces. The vitrified bond provides rigidity and porosity control suited to wet or dry surface grinding on reciprocating or rotary surface grinders equipped with a 3-inch spindle bore. The medium grade and grain structure rating of 5 make it appropriate for a broad range of general surface grinding tasks on hardened and unhardened steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile — compatible with standard surface grinder spindle configurations\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive, semi-friable — self-sharpening characteristics reduce glazing on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond — provides rigidity and maintains wheel form during surface grinding passes\u003c\/li\u003e\n  \u003cli\u003e60 grit, J hardness, medium grade — balanced between aggressive stock removal and acceptable surface finish\u003c\/li\u003e\n  \u003cli\u003e3,250 RPM maximum rated speed — verify machine RPM does not exceed this rating before mounting\u003c\/li\u003e\n  \u003cli\u003eNon-porous, no recess, not tapered — straightforward mount with no recess fitment concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on surface grinders accepting a Type 1 straight wheel with a 10-inch diameter, 3\/4-inch thickness, and 3-inch arbor hole running at or below 3,250 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheels must be installed and dressed by a qualified machinist or grinding machine operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Before mounting, perform a ring test to check for cracks, and confirm the machine spindle speed does not exceed the 3,250 RPM wheel rating. Always use proper flanges and a blotter on each side of the wheel, and stand clear of the wheel plane during startup. Never force the arbor hole — the wheel should slide onto the spindle without binding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\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: 5\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: 3,250\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 29A60J5V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253269672\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51752462188850,"sku":"66253269672","price":65.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f2563879cdb7f7fdbfdecf449423ec7.jpg?v=1788928286","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269672-surface-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
