Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and a coarse finish pass across flat workpiece surfaces. The wheel measures 7 inches in diameter and 1 inch thick, with a 1-1\/4 inch arbor hole for secure spindle mounting. Rated at a maximum of 3,600 RPM, it carries an I hardness code and a semi-friable grain structure, making it well-suited for controlled material removal where wheel breakdown and self-sharpening action are needed. Machinists and tool-room operators will find this wheel straightforward to dress and true on compatible surface grinders.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on horizontal-spindle surface grinders that accept Type 5 recessed wheels. The single-side recess measures 3 inches in diameter, which reduces wheel weight and clears spindle flanges on compatible machines. The coarse 46-grit specification targets roughing passes and rapid stock removal rather than finish grinding. It is a standard fit for job shops, maintenance facilities, and production environments where a reliable aluminum oxide surface grinding wheel is needed for everyday ferrous metal work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 single-side recessed wheel — 3-inch recess diameter clears spindle hardware on compatible grinders\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, repeatable cut action\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for aggressive stock removal on ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eI hardness rating with semi-friable grain structure promotes controlled self-sharpening\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 3,600 RPM — do not exceed this rating\u003c\/li\u003e\n\u003cli\u003eNon-porous construction maintains wheel integrity under coolant or dry grinding conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for horizontal-spindle surface grinders that accept Type 5 recessed grinding wheels with a 1-1\/4 inch arbor hole and a 7-inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheel installation and dressing should be performed by a qualified machinist or tool-room technician following ANSI B7.1 safe-use guidelines. Before mounting, inspect the wheel for cracks or chips using the ring test — do not mount a damaged wheel. Power down and lock out the grinder before changing wheels, and ensure the new wheel is properly flanged and torqued per the machine manufacturer's specifications. Always perform a one-minute free-spin guard test at full RPM before bringing the wheel into contact with a workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5 (Single-Side Recessed)\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 (Coarse)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\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 Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\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: 3,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 29A46I6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: 66253269748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51728532177202,"sku":"66253269748","price":50.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b49833ced0d50c5f002a3ffe772a7699.jpg?v=1788692842","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269748-type-5-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
