The tool measures 3\/8 inch (0.3750 inches) in diameter with a 0.0200-inch corner radius, a 1.1250-inch reach length, and a 3-inch overall length. Four right-hand spiral flutes with a medium 30-degree helix angle deliver efficient chip evacuation during both roughing and finishing passes. An AlTiN (aluminum titanium nitride) PVD coating adds heat and wear resistance, making this end mill a practical choice for machinists working in aerospace, oil and gas, and precision manufacturing applications.\u003c\/p\u003e\n\u003cp\u003eThe TC74423 is suited for cutting superalloys, titanium alloys, Inconel, stainless steel, alloy steel, cast iron, and other ferrous metals. Its long-length geometry and straight cylindrical shank make it compatible with standard toolholders used in CNC vertical and horizontal machining centers. The single-end, corner radius end type with right-hand cutting direction is appropriate for slotting, profiling, and contouring operations where edge blending and surface finish are priorities. This tool is typically selected by CNC machinists and tool and die professionals running difficult-to-machine materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0200-inch corner radius (0.50 mm) reduces stress concentrations and extends tool life at workpiece edges\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides elevated heat resistance for dry or near-dry cutting of hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute solid carbide construction supports aggressive feed rates in both roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003e30-degree medium helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eLong-length reach of 1.1250 inches suits deep-pocket and extended-reach machining applications\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank (3\/8 inch, h6 tolerance) fits standard collet chucks and shrink-fit toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 3\/8-inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and the tool magazine or turret is in a safe position before changing tooling. Confirm shank seating depth and runout with a dial indicator before beginning a cut, and verify toolholder torque to the toolholder manufacturer specifications. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches (0.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0010 to +0.0010 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.1250 inches (1-1\/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\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees (Medium)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Superalloys, Titanium Alloy, Inconel, Stainless Steel, Alloy Steel, Cast Iron, Ferrous Metal, High-Temperature Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: TC74423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51749878726962,"sku":"TC74423","price":83.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd47e8aa7038d40d36ccb972eb4125a1_87dc4e55-b266-4e60-a67b-e2a373ed6f5d.jpg?v=1788911614","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc74423-corner-radius-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
