It carries a 3\/8-inch corner radius, a 1-inch mill diameter, and three straight flutes with a right-hand cutting and flute direction. The AlTiN coating improves heat resistance and extends tool life when cutting ferrous and exotic materials at elevated speeds. At 4 inches overall length with a 1-inch cylindrical shank, it mounts securely in standard end mill holders. Machinists and CNC operators in job shops and production facilities are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for edge rounding and radius milling operations on steel, stainless steel, cast iron, non-ferrous metals, and super alloys including titanium. The double-end configuration provides two usable cutting ends, reducing per-edge tooling cost in high-volume applications. Its micrograin carbide substrate supports interrupted cuts and abrasive materials where coarser carbide grades would fail prematurely. It is appropriate for both vertical machining centers and manual knee mills with rigid setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design delivers two cutting ends per tool for extended service life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for ferrous and super alloy cutting\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e3\/8-inch corner radius with 0.240-inch tip diameter for consistent edge profiling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight flute geometry with 0-degree helix angle\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad range of workpiece materials including titanium and super alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on steel, stainless steel, cast iron, non-ferrous metals, and super alloys and titanium.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the 1-inch shank fully in a properly sized end mill holder or collet and torque the retention hardware to the machine tool manufacturer's specification. Verify runout with a dial indicator before beginning a cut, and select feeds and speeds appropriate for the workpiece material and coating type per your tooling reference data.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.240 inches\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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 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\u003c\/strong\u003e: AlTiN\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\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\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\u003eWeight\u003c\/strong\u003e: 0.7 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: INTERNAL TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68-1370-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67914446405938,"sku":"68-1370-C","price":754.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d663f862331c753df232469dd8a6e1f_caf1defe-7bd5-4658-9e4d-46b3c4a41eb3.jpg?v=1791249300","url":"https:\/\/voomisupply.com\/products\/internal-tool-68-1370-c-corner-rounding-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
