It features a 0.0984-inch corner radius, a 3\/8-inch mill diameter, and three straight flutes with a right-hand cutting direction. The AlTiN coating provides heat and wear resistance suited to high-temperature cutting environments. With a 2.5-inch overall length and a 0.3750-inch cylindrical shank, this tool is sized for standard toolholders used in CNC milling and manual mill operations. It is installed and operated by machinists and tool-and-die professionals in production and job-shop settings.\u003c\/p\u003e\u003cp\u003eThis corner rounding end mill is suited for edge-breaking and radius-blending operations on steel, stainless steel, cast iron, non-ferrous metals, super alloys, and titanium. The double-end configuration extends tool life by providing two usable cutting ends. The micrograin carbide substrate supports tight tolerances in both light-finishing and moderate-stock-removal passes. Typical applications include deburring sharp corners, producing uniform fillet radii on machined components, and finishing edges prior to assembly or inspection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design provides two cutting ends, maximizing tool value per unit\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and tool life in ferrous and high-temperature alloy cutting\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports precise, repeatable radius profiles\u003c\/li\u003e\n\u003cli\u003e0.0984-inch corner radius with a 0.1150-inch tip diameter for controlled edge geometry\u003c\/li\u003e\n\u003cli\u003eThree straight flutes with right-hand helix for smooth chip evacuation\u003c\/li\u003e\n\u003cli\u003eCompatible with primary workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, 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.

Secure the cylindrical shank in a properly sized collet or end mill holder to the torque specifications of the toolholder manufacturer. Inspect both cutting ends for chipping or wear before use. Coolant-through is not supported on this tool; use external flood or mist coolant as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0984 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.1150 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: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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\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\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: 0.45 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 68-1302-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67913058550066,"sku":"68-1302-C","price":136.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d663f862331c753df232469dd8a6e1f_52ee0ac8-316b-4214-82d2-8181170d5bcf.jpg?v=1791242072","url":"https:\/\/voomisupply.com\/products\/internal-tool-68-1302-c-corner-rounding-end-mill-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
