The tool features a 0.50 mm cutting diameter, a 1\/64 inch (0.40 mm) length of cut, and a 2-flute spiral geometry with a 20-degree right-hand helix. An AlTiN Nano PVD coating provides thermal resistance and surface hardness at the cutting edge, making this end mill suited for high-speed finishing passes where tool life and dimensional accuracy are critical. The straight cylindrical shank measures 1\/4 inch in diameter. Machinists and tool-and-die professionals working with hardened workpieces typically specify this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill belongs to the Harvey Tool End Mills for Hardened Steels - Finishers - Ball series. It is intended for finishing operations on hardened materials, with secondary suitability for steel, stainless steel, and cast iron. The extended-reach geometry and stub-length cut make it appropriate for tight-tolerance profiling, slotting, and contouring in die cavities, mold features, and precision components where a fine surface finish is required. The centercutting design permits direct plunge entry. Single-end configuration maximizes rigidity at this micro-diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.50 mm ball cutting diameter with a nose radius of 0.0100 inches for fine finish work\u003c\/li\u003e\n  \u003cli\u003eAlTiN Nano PVD coating for thermal and wear resistance in hardened material applications\u003c\/li\u003e\n  \u003cli\u003e2-flute, right-hand spiral geometry at 20-degree helix angle\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eExtended reach with a 0.1000 inch reach length and 0.0840 inch neck length\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch straight cylindrical shank with h6 diameter tolerance for precise toolholder fit\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 \/ -0.0006 inches for tight dimensional control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on hardened steels as the primary workpiece material, with secondary compatibility for steel, stainless steel, and cast iron.

Ensure the spindle and toolholder are clean and within runout tolerance before seating the shank, as micro-diameter end mills are sensitive to setup error. Confirm coolant-through is not required for this tool; external coolant or air blast is appropriate. Follow the machine tool manufacturer and tooling series guidelines for speeds, feeds, and depth-of-cut recommendations when cutting hardened materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.50 mm (0.0200 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/64 inch (0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.0840 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.1000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN Nano (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 38720-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732615397682,"sku":"38720-C6","price":141.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fe705d03cc150ca73779bd2757e690.jpg?v=1788745047","url":"https:\/\/voomisupply.com\/products\/harvey-tool-38720-c6-ball-end-mill-0-50mm-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
