Shaped as an A4 tree profile, this mounted point fits a 1\/4-inch shank and runs at a maximum rated speed of 28,550 RPM. The vitrified bond holds the 60-grit aluminum oxide abrasive securely, delivering consistent stock removal and a medium-grade finish. At 0.02 pounds, it is a lightweight consumable suited for use in die grinders, rotary tools, and pneumatic grinding handpieces used in fabrication, maintenance, and toolroom applications.\u003c\/p\u003e\u003cp\u003eThis mounted point is appropriate for internal grinding, port work, weld cleanup, and contour finishing in both shop and field settings. The A4 tree shape allows access to curved surfaces, recesses, and angled bores where flat or cylindrical wheels cannot reach. It is commonly used by machinists, maintenance mechanics, and metalworking tradespeople working on ferrous metals, castings, and hardened steel components. The pink aluminum oxide composition is well suited to general-purpose precision grinding where heat-sensitive materials or tight tolerances are involved.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA4 tree profile for grinding recesses, contoured bores, and irregular surfaces\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade for efficient stock removal with a semi-refined finish\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled cutting action\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter compatible with standard die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003eRated to 28,550 RPM for use with high-speed pneumatic and electric handpieces\u003c\/li\u003e\n\u003cli\u003e1-1\/4-inch head thickness and 1-1\/2-inch shank length for reach into confined areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for die grinders, rotary tools, and pneumatic grinding handpieces accepting a 1\/4-inch straight shank mounted point.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounted points must be installed by personnel familiar with abrasive tooling safety and applicable ANSI B11 and OSHA grinding standards. Before mounting, confirm the tool spindle RPM does not exceed the 28,550 RPM rating marked on this point. Power down and disconnect the tool from its air or electrical supply before changing mounted points. Inspect the point for chips or cracks before each use and discard any damaged abrasive immediately.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: A4 Tree\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: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Pink\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 28,550\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131514\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: 66253291558\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51746313830706,"sku":"66253291558","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f355eb1925eb6d1891e54728ccf74cf.jpg?v=1788868224","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253291558-a4-mounted-point-60-grit-1-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
