With a 1\/2-inch mill diameter, a 1\/8-inch corner radius, and 5 straight flutes in a right-hand cutting and flute direction, this tool delivers consistent, repeatable radii on hardened and difficult-to-machine workpiece materials. The AlTiN coating provides elevated heat resistance and extended tool life under high-speed cutting conditions. A 0 degree helix angle supports stable engagement on straight-flute passes. Both ends are usable, reducing tooling cost per edge on the shop floor.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, super alloys, and titanium  -  workpiece material codes P, M, and S. It is a strong fit for job shops and production machining environments where edge-breaking and radius profiling are performed on tough alloys. The double-end configuration is particularly useful in high-volume operations where maximizing edge count per tool reduces changeover frequency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8-inch corner radius (0.1250 inches decimal) for consistent edge profiling\u003c\/li\u003e\n  \u003cli\u003e5 straight flutes with right-hand cutting and flute direction\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-temperature wear resistance on hard alloys\u003c\/li\u003e\n  \u003cli\u003eDouble-end design doubles usable cutting edges per tool\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity in ferrous and super alloy cutting\u003c\/li\u003e\n  \u003cli\u003eCylindrical 1\/2-inch shank fits standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, super alloys, and titanium workpieces; compatible with standard 1\/2-inch cylindrical shank tool holders and collet chucks on vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the 1\/2-inch cylindrical shank in a properly sized collet or end mill holder and verify runout before initiating a cut. Confirm spindle speed and feed rate are appropriate for the workpiece material and coating type before engaging the tool. Coolant-through is not supported on this tool; apply external coolant or cutting fluid as required by the workpiece material.\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 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 7\/32 inch (0.2190 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Super Alloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 168\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 168-1090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67906936176946,"sku":"168-1090","price":226.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e98efe3e505359feb595c13ea5683ee.jpg?v=1791172623","url":"https:\/\/voomisupply.com\/products\/internal-tool-168-1090-corner-rounding-end-mill-1-2-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
