Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and good wheel life in typical surface grinding applications. The wheel measures 7 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole. At 60 grit and H hardness, it sits in the medium-fine range for aggressive-yet-controlled material removal. Rated to 3600 RPM maximum, it is intended for use on reciprocating and rotary surface grinders operated by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations in machine shops, maintenance facilities, and tool rooms. The aluminum oxide grain and vitrified bond make it a reliable choice for grinding carbon steel, alloy steel, and similar ferrous workpieces. The non-porous, semi-friable grain structure with a grain structure rating of 6 supports consistent self-dressing behavior, helping maintain a sharp cutting face during extended runs. It is appropriate for both roughing passes and finish grinding where a 60-grit surface finish is acceptable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess for straightforward mounting on standard surface grinder spindles\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with semi-friable grain promotes controlled self-sharpening during use\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and good form-holding for flat surface work\u003c\/li\u003e\n\u003cli\u003eH hardness (soft-to-medium range) reduces loading when grinding harder steel alloys\u003c\/li\u003e\n\u003cli\u003e60 grit delivers moderate stock removal with a reasonably smooth finish\u003c\/li\u003e\n\u003cli\u003eWhite wheel color aids visual inspection of wheel condition between dresses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for surface grinders accepting a 7-inch diameter, 1-1\/4 inch arbor hole, 1\/2 inch thick Type 1 wheel running at or below 3600 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheels must be installed and dressed by a qualified machinist or grinder operator following ANSI B7.1 safe use standards. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the maximum rated RPM of 3600. Power down and lock out the grinder before changing wheels, and use the correct flanges and blotters as specified by the machine manufacturer. Eye and face protection rated for grinding operations is required during use and dressing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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\u003ePorosity\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\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\u003eRecess Type\u003c\/strong\u003e: No Recess\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: 23A60H6V31\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: 66253255894\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51734891266354,"sku":"66253255894","price":40.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01755bbb4e23a591e534b825d14367a9.jpg?v=1788767667","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255894-surface-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
