It produces a 1\/4-inch radius with a 5\/8-inch mill diameter and features an AlTiN (aluminum titanium nitride) coating that extends tool life under high-heat cutting conditions. With 3 straight flutes and a right-hand cutting direction, it delivers clean, consistent radii on ferrous and non-ferrous materials alike. Overall length is 3.5 inches and the cylindrical shank diameter is 5\/8 inch. Machinists and tool-and-die professionals reach for this end mill when edge finishing demands tight tolerances and surface quality.\u003c\/p\u003e\n\u003cp\u003eThis corner rounding end mill is suited for use on steel, stainless steel, cast iron, non-ferrous metals, super alloys, and titanium. It fits into standard CNC machining centers and manual milling setups that accept a 5\/8-inch shank. The double-end configuration provides two usable cutting ends, extending service intervals between tool changes. Typical applications include rounding sharp edges on machined components, producing consistent radii on brackets, housings, and structural parts across both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous and high-temperature alloy cuts\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, reducing per-edge cost\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction delivers rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e3 straight flutes with right-hand helix cut cleanly across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch corner radius and 0.120-inch tip diameter for precise edge profiling\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on standard milling machines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, cast iron, non-ferrous metals, super alloys, and titanium workpieces.

Verify that the tool holder is clean and free of chips before seating the 5\/8-inch shank. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material being cut. Inspect both cutting ends for chipping or wear before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.120 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: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\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\u003eFlute Type\u003c\/strong\u003e: Straight\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\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\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: 0.6 pounds\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: 68-1345-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67911356514610,"sku":"68-1345-C","price":344.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d663f862331c753df232469dd8a6e1f_75fd7b5d-ef7b-446d-9c7b-6e42ccf6a41c.jpg?v=1791210142","url":"https:\/\/voomisupply.com\/products\/internal-tool-68-1345-c-corner-rounding-end-mill-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
