Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action on ferrous metals and general-purpose materials. At 46 grit with an H hardness code, it falls in the coarse-grade range, making it suited for aggressive material removal where finish tolerances are secondary to throughput. The wheel is rated to 3600 RPM and carries a semi-friable grain structure that supports continuous self-sharpening during the cut. Machinists and surface grinding technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis wheel fits standard surface grinders accepting a 7-inch diameter, 1-inch thick wheel with a 1-1\/4-inch arbor hole. The Type 5 profile features a single-side recess with a 3-inch recess diameter, which reduces wheel-to-workpiece contact area and helps manage heat buildup during extended grinding passes. It is appropriate for job shop and production environments handling tool steel, mild steel, cast iron, and similar ferrous stock. The white aluminum oxide composition with vitrified bond makes it a common choice for tool rooms requiring consistent cut rate and predictable wheel wear.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 single-side recessed profile with 3-inch recess diameter for reduced contact area and improved coolant access\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for rigid, consistent cutting action\u003c\/li\u003e\n  \u003cli\u003e46 grit, H hardness coarse-grade wheel suited for aggressive material removal on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure promotes self-sharpening and extends usable wheel life\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color indicates aluminum oxide composition standard to general-purpose tool room use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock grinding wheel for surface grinders accepting a 7-inch diameter, 1-1\/4-inch arbor hole, 1-inch thick Type 5 wheel at up to 3600 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eWheel mounting and dressing should be performed by a qualified machinist or grinding technician following the machine manufacturer's guard and flange specifications. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips using the ring test before mounting — do not use a damaged wheel. Do not exceed the 3600 RPM maximum speed rating marked on the wheel.\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\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\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\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: White\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: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A46H6V31\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: 66243496722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51730206196018,"sku":"66243496722","price":50.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7fbad95da7a2c3a206479c056015358.jpg?v=1788713321","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66243496722-type-5-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
