Built from aluminum oxide abrasive, it operates at a maximum speed of 3600 RPM and carries a 46 grit, coarse-grade cutting structure suited for aggressive material removal on ferrous metals. At 7 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole, this wheel fits standard horizontal-spindle surface grinders. The G hardness code indicates a soft bond grade, which releases abrasive grains readily to maintain a free-cutting action across the work surface.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for surface grinding applications in machine shops, tool rooms, and general metalworking operations. The porous structure promotes coolant flow and reduces heat buildup during extended grinding passes. Its ruby-colored aluminum oxide grain is well suited for general-purpose grinding on carbon steel, alloy steel, and similar ferrous workpieces. Machinists and tool grinders install this wheel on horizontal-spindle reciprocating surface grinders requiring a standard 1-1\/4 inch bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain for general-purpose ferrous metal grinding\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade delivers aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eG hardness (soft bond) promotes free-cutting action and reduced workpiece heat\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure supports coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003eType 1 straight-wheel configuration for horizontal-spindle surface grinders\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type 1 replacement grinding wheel for horizontal-spindle surface grinders accepting a 7 inch diameter, 1\/2 inch thick wheel with a 1-1\/4 inch arbor bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 safety standards. Always power down and lock out the grinder before mounting or removing wheels. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the marked maximum RPM of 3600. Use proper flanges and blotters as specified by the machine manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 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\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\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 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: 66253269898\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51744490815794,"sku":"66253269898","price":34.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c27a7529b0ff1ee2ee328a1b859e858.jpg?v=1788857291","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269898-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
