It has a 5\/16 inch (0.3125 inch) mill diameter, a 0.0200 inch corner radius, and a 2-flute configuration with a 45-degree high helix spiral flute geometry. The ZrN (zirconium nitride) PVD coating reduces built-up edge and improves tool life in non-ferrous applications. At 3 inches overall length with a 1.375 inch length of cut, this is a long-series end mill suited to reaching into pockets and slots where shorter tooling falls short. It is centercutting and runs right-hand flute direction with right-hand cutting direction.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where non-ferrous metal stock — aluminum, brass, and bronze — requires a corner radius profile to reduce stress concentrations at part corners or to produce radiused slot bottoms. The long-series reach makes it useful for deeper cavity work. It accepts standard straight-cylindrical toolholders with a 5\/16 inch shank diameter. The coarse pitch and 2-flute design prioritize chip clearance and chip evacuation over tool rigidity, making it a strong choice for high-feed aluminum roughing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZrN PVD coating for reduced built-up edge and extended tool life in non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.0200 inch corner radius with a tolerance of -0.0010 to +0.0010 inch\u003c\/li\u003e\n  \u003cli\u003e45-degree high helix angle promotes efficient chip evacuation in aluminum and soft metals\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry directly into workpiece material\u003c\/li\u003e\n  \u003cli\u003eLong-series geometry with 1.375 inch length of cut for deep pocket and slot applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance versus HSS tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 5\/16 inch shank diameter. Optimized for milling non-ferrous metals including aluminum, brass, and bronze.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a clean, properly sized collet or end mill holder to the recommended gauge length before tightening to toolholder specifications. Verify runout with a dial indicator before beginning a cut — excess runout accelerates corner radius wear and degrades surface finish. Do not use this end mill on ferrous materials; the ZrN coating is optimized for non-ferrous applications and tool life will degrade significantly on steel or cast iron. Follow machine tool manufacturer guidelines for spindle speed and feed rate when setting up for aluminum or brass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch), tolerance h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches (0.50 mm), tolerance -0.0010 to +0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.375 inches (1-3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal (Aluminum, Brass, Bronze)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC65320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51752960721202,"sku":"TC65320","price":118.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa124436483d7bd1fbdcf43fd767e2fe_4c3f8835-f30a-4a6f-acf1-e550967b9833.jpg?v=1788931560","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc65320-corner-radius-end-mill-5-16-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
