Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and thermal stability across extended grinding operations. At 100 grit with a K hardness rating, it sits in the fine-grade range, making it well suited for finish grinding passes where surface finish quality matters. The non-porous, semi-friable grain structure with a grain structure rating of 6 helps the wheel self-dress during use, reducing loading on softer workpiece materials. Licensed HVAC, mechanical, and tool-room professionals will recognize the vitrified bond as a reliable choice for wet or dry precision surface work.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders in tool rooms, maintenance shops, and production grinding environments. The Type 1 flat wheel geometry fits standard surface grinder spindle arbors. At 7 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole, it mounts directly to machines configured for that bore size. The 3600 RPM maximum speed rating must be observed to ensure safe operation. Typical applications include flat surface finishing, tool reconditioning, and light material removal on hardened steel and similar ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut and long wheel life\u003c\/li\u003e\n  \u003cli\u003e100 grit fine grade for finish grinding and tight surface finish tolerances\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium) holds abrasive grain firmly while allowing controlled breakdown\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure (grade 6) promotes self-dressing and reduces loading\u003c\/li\u003e\n  \u003cli\u003eNon-porous wheel body rated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eType 1 flat profile with no recess fits standard surface grinder arbors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fitment for surface grinders accepting a Type 1 flat wheel with a 1-1\/4 inch arbor hole and a maximum operating speed of 3600 RPM or higher.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eWheel mounting must be performed by a qualified operator following ANSI B7.1 safe use standards for abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed stamped on the wheel, and always use the correct flanges and blotters supplied or specified for the machine.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Flat, No Recess)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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\u003ePorosity\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 23A100K6V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\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\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: 66253255876\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51747867754802,"sku":"66253255876","price":33.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/273938ace75f3cd4ad7625a894e37495.jpg?v=1788886439","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255876-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
