The vitrified bond holds 60-grit abrasive grains firmly, delivering consistent stock removal at a medium grade. This mounted point fits a 1\/4-inch shank collet and is rated to a maximum of 56,000 RPM, making it suitable for use in die grinders and rotary tools. The pink aluminum oxide construction is well suited for general-purpose grinding on ferrous metals and hard materials. Machinists, tool-and-die technicians, and maintenance professionals install this type of abrasive point for internal grinding and contour work.\u003c\/p\u003e\u003cp\u003eThis mounted point is used in shop maintenance, toolroom grinding, and fabrication applications where a standard grinding wheel cannot access the work surface. The ball profile of the A24 shape makes it effective for grinding concave surfaces, radiused recesses, and bore interiors. It is suitable for use on hardened steel, cast iron, and similar ferrous workpieces. The 3\/4-inch head thickness and 1-1\/2-inch shank length provide adequate reach and material for controlled grinding passes without excessive deflection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA24 ball point shape for grinding concave and recessed surfaces\u003c\/li\u003e\n\u003cli\u003e60-grit medium grade aluminum oxide abrasive for general-purpose stock removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond for consistent grain exposure and cool cutting action\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter compatible with standard die grinder collets\u003c\/li\u003e\n\u003cli\u003eRated to 56,000 RPM maximum for use in high-speed rotary tools\u003c\/li\u003e\n\u003cli\u003ePink aluminum oxide construction suited for ferrous metal grinding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock mounted point for die grinders and rotary tools accepting a 1\/4-inch shank collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounted points of this type are installed and changed by machinists, toolroom technicians, and maintenance professionals using a die grinder with a matching collet size. Always verify the tool spindle speed does not exceed the 56,000 RPM rating marked on this point before operation. Inspect the mounted point for cracks or chips before each use and discard any damaged abrasive. Power down and de-energize the tool completely before changing abrasive accessories.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: A24\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: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 56,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 66253291547\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51733274100018,"sku":"66253291547","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1dcf38179913031740b1087f560b2e3.jpg?v=1788753475","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253291547-mounted-point-ball-a24-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
