Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and controlled breakdown in demanding grinding applications. It carries a 46 grit rating for coarse-grade material removal and a G hardness code, placing it on the soft end of the hardness scale — a characteristic that promotes continuous grain exposure on harder workpiece materials. The wheel is semi-friable, supporting self-sharpening behavior under load. Rated to 3600 RPM, it is suited for use on standard surface grinding machines found in machine shops and tool rooms.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is intended for surface grinding operations where a recessed wheel geometry is required. The Type 5 form features a single-side recess measuring 2.75 inches in diameter, which allows clearance for flange mounting on compatible spindle configurations. The porous grain structure, designated 12, promotes coolant flow and chip clearance during wet or dry grinding passes. Machinists, tool and die makers, and maintenance technicians installing or dressing this wheel should verify spindle compatibility with the 1.25-inch arbor hole before mounting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 single-side recessed geometry with 2.75-inch recess diameter for flange clearance\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive, semi-friable — promotes self-sharpening on harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and form-holding during precision surface grinding\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eG hardness (soft rating) supports continuous grain fracture and fresh cutting edges\u003c\/li\u003e\n  \u003cli\u003eOpen grain structure (grade 12) aids coolant penetration and swarf evacuation\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use surface grinding wheel for Type 5 surface grinder spindle configurations accepting a 1.25-inch arbor hole and a 7-inch diameter wheel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or grinding equipment operator following the machine manufacturer's mounting procedures. Always power down and lock out the surface grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation — never mount a damaged abrasive wheel. Conduct a ring test per ANSI B7.1 guidelines and perform a no-load run-up at operating speed before applying the wheel to a workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\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: G (Soft)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 12 (Porous)\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\u003eWheel Color\u003c\/strong\u003e: Pink\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 29A46G12V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\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: 66253292507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51749186208050,"sku":"66253292507","price":123.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/048b3be2db1ab4ebdb02937134aee543.jpg?v=1788902984","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253292507-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
