It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, rated at a coarse 46 grit and I hardness code. With a semi-friable grain structure and porous construction, this wheel maintains consistent cut rates while resisting loading on ferrous metals. It is rated to a maximum of 3600 RPM and carries specification code 23A46I12V31. Machinists, tool grinders, and surface grinding operators are the primary installers and users of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel suits flat surface grinding applications in machine shops, maintenance facilities, and production environments. It performs on surface grinders where a coarse, free-cutting aluminum oxide wheel is appropriate for aggressive stock removal on steel, iron, and similar ferrous workpieces. The Type 1 straight profile fits standard surface grinder spindles with a 1-1\/4 inch bore. Its coarse grit and soft-to-medium hardness rating make it well suited for rapid stock removal rather than fine finish work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile fits standard surface grinder spindles\u003c\/li\u003e\n\u003cli\u003e46 grit coarse aluminum oxide abrasive for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous construction resists loading and maintains wheel integrity\u003c\/li\u003e\n\u003cli\u003eI hardness code and semi-friable grain structure support consistent cut-rate retention\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSpecification code 23A46I12V31 for cross-reference and replacement identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-fit surface grinding wheel for surface grinders accepting a Type 1 straight wheel with a 1-1\/4 inch arbor bore and 7 inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheels must be installed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Ensure the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Guard the wheel properly and allow it to run free for at least one minute before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\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: I\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 23A46I12V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253269564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51737740902706,"sku":"66253269564","price":45.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36e308ed6bc7f5d7000f417a872be7fd.jpg?v=1788793024","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269564-surface-grinding-wheel-7in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
