Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and good form retention during surface grinding operations. The wheel measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and is rated to a maximum of 3,250 RPM. At I hardness with a grain structure of 5, it sits in the medium-soft range, making it well-suited for harder workpiece materials where a softer wheel promotes continuous self-sharpening. Licensed machinists, tool-and-die makers, and grinding technicians are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on horizontal-spindle surface grinders in tool rooms, maintenance shops, and light manufacturing environments. The 10-inch diameter and 3-inch bore fit a wide range of production and bench-type surface grinders equipped with flanged spindles of that size. The vitrified bond resists heat buildup and maintains wheel geometry under moderate to heavy material removal on carbon steel, alloy steel, and similar ferrous workpieces. The non-porous, semi-friable aluminum oxide grain breaks down progressively to expose fresh cutting edges throughout the wheel life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain for progressive self-sharpening on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid form retention and resistance to heat during surface grinding\u003c\/li\u003e\n  \u003cli\u003e60 grit with I hardness rating delivers a medium-grade cut suitable for harder steels\u003c\/li\u003e\n  \u003cli\u003eGrain structure 5 balances porosity and bond post density for consistent stock removal\u003c\/li\u003e\n  \u003cli\u003eNon-recessed Type 1 straight wheel geometry fits standard horizontal-spindle surface grinder setups\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3,250 RPM — do not exceed this rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for horizontal-spindle surface grinders accepting a 10-inch diameter, 1-inch wide, 3-inch arbor hole Type 1 straight wheel.

Always perform a ring test before mounting to check for cracks, and ensure the spindle speed does not exceed the 3,250 RPM maximum marked on the wheel. Use proper flanges and a blotter on each side of the wheel; never apply excessive clamping force. Dress the wheel with an appropriate diamond dresser after mounting and before use to true the face and expose fresh abrasive.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\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 (Medium Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 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\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSemi-Friable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 23A60I5V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6 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: 66253255862\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51749484200242,"sku":"66253255862","price":108.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6586e7f5e043ee025611c84c8ef47057.jpg?v=1788906663","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255862-surface-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
