Built from aluminum oxide abrasive with a vitrified bond, it delivers consistent cut rates and good wheel life across a range of ferrous and toolroom applications. At 7 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole, this wheel mounts directly to compatible spindle configurations. The 60 grit, K hardness (medium grade) combination suits intermediate material removal where surface finish and geometry control matter. Rated to 3600 RPM, it is appropriate for bench and surface grinding machines operating within that speed range. The specification code 29A60K6V31 confirms the full bond, grain, and grade classification.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on horizontal-spindle surface grinders in machine shops, tool rooms, and maintenance departments. The Type 5 one-side recess profile with a 2-3\/4 inch recess diameter provides clearance for spindle flanges and is a standard configuration for surface grinding applications. The pink aluminum oxide grain is semi-friable, meaning it fractures under load to expose fresh cutting edges, making it well suited for general-purpose tool steel, high-speed steel, and similar ferrous workpieces. Installation and dressing are typically performed by machinists or skilled grinder operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 one-side recessed profile with 2-3\/4 inch recess diameter for spindle clearance\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled cut rates\u003c\/li\u003e\n  \u003cli\u003e60 grit, K hardness (medium grade) for intermediate stock removal\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure promotes self-sharpening under load\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n  \u003cli\u003eFull specification: 29A60K6V31\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type 5 surface grinding wheel replacement for horizontal-spindle surface grinders accepting a 7 inch diameter, 1-1\/4 inch arbor hole wheel rated to 3600 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and dressing of grinding wheels should be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always perform a ring test before mounting and verify the machine spindle speed does not exceed the 3600 RPM rated wheel speed. Power down and lock out the grinder before changing wheels. Never exceed the rated maximum RPM under any operating condition.\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 6\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Pink\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Specification Code\u003c\/strong\u003e: 29A60K6V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: 66253269770\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":67582062821682,"sku":"66253269770","price":48.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d55e2fcbe51b74e07fd8e254900bdc22.jpg?v=1790412418","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269770-surface-grinding-wheel-7in-60g","provider":"Voomi Supply","version":"1.0","type":"link"}
