With a 0.020-inch (0.5 mm) mill diameter and a 0.005-inch corner radius, this tool is built for tight-tolerance work where edge integrity matters. The four-flute, right-hand spiral configuration supports both roughing and finishing passes in a single setup. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and wear protection, extending tool life when cutting ferrous and non-ferrous materials. Machinists and CNC operators working in tool rooms, job shops, and production environments rely on tools like this for micro-scale contouring and profile milling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for steel, stainless steel, cast iron, non-ferrous metals, and composite materials. The stub and standard series designation indicates a compact geometry optimized for rigidity in miniature milling applications, making it appropriate for high-speed CNC machining centers and micro-machining setups where runout control and tool stiffness are critical. It is a single-end, center-cutting tool, enabling plunge entry as well as conventional side milling. The straight cylindrical shank fits standard 1\/8-inch toolholders and collet systems commonly found on CNC mills and micro-machining spindles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.020-inch (0.5 mm) mill diameter for miniature and micro-scale milling operations\u003c\/li\u003e\n  \u003cli\u003e0.005-inch corner radius with a tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for elevated thermal resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut, right-hand spiral geometry supports both roughing and finishing\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilled pilot holes\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability in tight-tolerance cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/8-inch bore toolholders and collet systems on CNC machining centers capable of accommodating miniature end mill tooling.

Ensure the machine spindle is fully stopped and the controller is in a safe state before changing tooling. Seat the 1\/8-inch straight shank fully into the collet or toolholder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout at the tool tip with a dial indicator before beginning a cut, as excessive runout will accelerate wear and compromise corner radius accuracy on a tool at this diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.020 inches (0.5 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 to minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 to minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.010 to minus 0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\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\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Corner Radius - Stub Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 26320-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51734780444978,"sku":"26320-C3","price":92.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_792e4a8a-0fdf-46b8-9e76-65f3fbee1109.jpg?v=1788766961","url":"https:\/\/voomisupply.com\/products\/harvey-tool-26320-c3-corner-radius-end-mill-0-5mm-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
