Made from aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent, controllable stock removal at a coarse 46 grit. At 12 inches in diameter and 2 inches thick with a 5-inch arbor hole, it is sized for industrial surface grinders used in machine shops and maintenance grinding applications. The white aluminum oxide grain is semi-friable, meaning it self-sharpens during use to maintain cut rate and reduce heat buildup at the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding operations in machine shops, tool rooms, and industrial maintenance environments. The Type 7 double-recessed configuration with two-side recessing and a 7.5-inch recess diameter accommodates compatible surface grinder spindle flanges. Coarse grit is appropriate for aggressive stock removal on flat surfaces, weld cleanup, and initial workpiece conditioning before finish grinding. Installation and operation are typically performed by machinists or skilled maintenance technicians on horizontal-spindle surface grinders rated for this wheel size and speed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain — effective on hardened steels and ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction for rigidity and consistent form holding\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure promotes self-sharpening and cooler cutting\u003c\/li\u003e\n  \u003cli\u003eType 7 double-recessed profile with two-side recesses for spindle flange clearance\u003c\/li\u003e\n  \u003cli\u003eCoarse 46 grit and J hardness rating suit aggressive stock removal applications\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed rated at 2069 RPM — do not exceed\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 7 wheel with a 12-inch diameter, 2-inch face width, and 5-inch arbor bore.

Before mounting, ring-test the wheel for cracks and confirm the machine's rated spindle speed does not exceed 2069 RPM. Power down and lock out the grinder before changing wheels, and use only properly matched flanges and blotters. Always dress the wheel with an appropriate diamond or rotary dresser before grinding to true the face and expose fresh abrasive grain.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 7.5 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: Two-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 7\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: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\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\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2069\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A46J5V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15 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: 66243496733\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51728194109746,"sku":"66243496733","price":129.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7bb005120a7a8f95003e17894f5341d7.jpg?v=1788689307","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66243496733-type-7-surface-grinding-wheel-46g","provider":"Voomi Supply","version":"1.0","type":"link"}
