Built from solid carbide and coated with an amorphous diamond PVD finish, this single-end tool delivers wear resistance and thermal stability when cutting ferrous and non-ferrous materials. The 0.50 mm cutting diameter and 0.1000 inch length of cut make it well suited for fine-detail milling where tight tolerances and small feature sizes are required. A 30-degree helix angle and three-flute spiral geometry promote efficient chip evacuation and smooth cutting action at elevated spindle speeds.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, high-speed milling machines, and precision manual mills where miniature tooling is required. Primary workpiece materials include steel, stainless steel, cast iron, aluminum and other non-ferrous alloys, and CFRP composite materials. The 1\/8 inch shank diameter suits standard miniature collet chucks and tool holders commonly found in precision machining environments. It is sold as a single-end tool with no chipbreaker geometry, making it appropriate for smooth-finish passes in confined pockets and contour work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.50 mm cutting diameter for miniature and fine-detail milling operations\u003c\/li\u003e\n\u003cli\u003eAmorphous diamond PVD coating provides high surface hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral geometry with 30-degree right-hand helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad range of workpiece materials including steel, stainless steel, cast iron, aluminum, and CFRP\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in precision CNC and manual milling applications requiring miniature square end mill tooling with a 1\/8 inch shank.

Ensure the collet chuck and tool holder are clean and free of debris before seating the 1\/8 inch shank. Verify runout with a dial indicator after clamping, as excessive runout significantly reduces tool life at this diameter. Follow the machine manufacturer and tooling manufacturer recommendations for speeds and feeds when working with miniature carbide end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eLength of Cut\u003c\/strong\u003e: 0.1000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: Amorphous Diamond (PVD Diamond)\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\u003eExtended Reach\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Square - Long Flute\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 12720-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51733298086194,"sku":"12720-C4","price":83.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50214e3950c3ec2771b92c48a63192ff_44047a1d-bff1-46e4-a13a-cc6dd0d23b08.jpg?v=1788753755","url":"https:\/\/voomisupply.com\/products\/harvey-tool-12720-c4-square-end-mill-0-50mm-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
