Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles demanding cuts in steel, stainless steel, cast iron, non-ferrous metals, and super alloys including titanium. The tool carries a 3\/16 inch (0.1875 inch) corner radius, a 1\/2 inch mill diameter, and three straight flutes ground for right-hand cutting and right-hand flute direction. With a 0.120 inch tip diameter and 3 inch overall length, it fits standard toolholding setups used by machinists and tool-and-die professionals in both production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for profiling and edge-breaking operations on ferrous and non-ferrous parts where a precise corner radius is required. Typical applications include rounding sharp edges on milled steel and stainless components, blending transitions on cast iron housings, and finishing profile passes on titanium and super alloy workpieces. The double-end configuration extends tool life by providing two usable cutting ends per tool, making it practical for high-volume runs as well as prototype work. The 1\/2 inch cylindrical shank seats directly into standard ER or end mill collet chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch corner radius for consistent, repeatable edge profiling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for hardness and wear resistance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in ferrous, stainless, and titanium applications\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eThree straight flutes with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch cylindrical shank compatible with standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with 1\/2 inch collet or end mill toolholding.

Secure the 1\/2 inch shank fully into a clean, undamaged collet or end mill holder and torque to the toolholder manufacturer's specification before running. Inspect both cutting ends for edge condition before use; do not run a chipped or damaged end. Coolant-through is not supported on this tool, so apply flood or mist coolant externally at the cutting zone as appropriate for the workpiece material and cut parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.120 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Super Alloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 68\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 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: INTERNAL TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68-1325-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67918519435570,"sku":"68-1325-C","price":199.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d663f862331c753df232469dd8a6e1f_7631c8e2-0d7d-49a4-ba15-b305aab92346.jpg?v=1791270711","url":"https:\/\/voomisupply.com\/products\/internal-tool-68-1325-c-corner-rounding-end-mill-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
