Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention across a wide range of surface grinding applications. At 6 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole, it mounts directly to standard surface grinder spindles. The 80 grit, K hardness (medium) rating positions it for general-purpose finish grinding where a balance of material removal and surface quality is required. Rated at 5,410 RPM maximum, it suits most benchtop and reciprocating-table surface grinders in shop and tool-room environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding operations on hardened steel, tool steel, and similar ferrous workpieces in machine shops, tool rooms, and maintenance facilities. The medium grade and semi-friable aluminum oxide grain structure allow the wheel to self-dress at a controlled rate, maintaining sharpness during extended passes. It is a practical choice for grinding flat surfaces, sharpening tooling, and light die work where close tolerances and consistent finishes are the priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for reliable performance on ferrous metals and hardened steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity, porosity control, and good form holding\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade for a balance of stock removal rate and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eK hardness code with semi-friable grain structure supports controlled self-dressing\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess and non-tapered face\u003c\/li\u003e\n  \u003cli\u003e5,410 RPM maximum operating speed rated for standard surface grinder use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type 1 straight surface grinding wheel for use on surface grinders accepting a 6 inch diameter wheel with a 1-1\/4 inch arbor hole and a maximum spindle speed of 5,410 RPM or lower.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or grinding equipment operator in accordance with ANSI B11.9 grinding safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test by tapping the wheel lightly. Power down and lock out the grinder before mounting or changing wheels. Never exceed the marked maximum RPM rating of the wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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 Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 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\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,410\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 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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A80K6V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66253255426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51731715064114,"sku":"66253255426","price":49.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65b2e0c57b675321cba9cd9a2f3f9232.jpg?v=1788734182","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255426-surface-grinding-wheel-6in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
