Built from solid carbide with an AlTiN coating, this single-end tool measures 0.5 mm (0.0200 inches) in cutting diameter with a 1\/32-inch length of cut and an overall length of 2.5 inches. The 30-degree helix angle and 3-flute geometry promote efficient chip evacuation and smooth cutting action in ferrous and hardened materials. The extended reach configuration and 0.125-inch shank diameter make it well suited for deep-pocket and restricted-access machining operations performed by experienced machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and high-speed spindle applications where micro-diameter tooling is required. Typical applications include mold and die work, medical component machining, aerospace part finishing, and any operation demanding sub-millimeter cutting diameter with consistent runout control. The right-hand cut and right-hand flute direction are standard for conventional CNC setups. Center-cutting capability allows plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 mm (0.0200 inches) cutting diameter for micro-scale milling operations\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal protection and extended tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip clearance with surface finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle supports smooth cutting action and reduced deflection\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eExtended reach configuration suits deep-pocket and restricted-access features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and high-speed spindles accepting a 1\/8-inch straight shank.

Secure the 0.125-inch shank in a precision collet or tool holder rated for the intended spindle speed to minimize runout. Inspect the collet and holder for contamination or wear before seating the tool, as micro-diameter end mills are sensitive to runout-induced breakage. Follow the tool manufacturer and machine builder guidelines for feed rate, spindle speed, and depth of cut when programming operations with sub-millimeter tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 mm (0.0200 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/32 inch (0.03 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 937020-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747682812210,"sku":"937020-C3","price":80.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a1577116c7f853f774ec71d1ca21e13_0abeec79-afc9-4da5-ae5d-9844da4dfb27.jpg?v=1788884475","url":"https:\/\/voomisupply.com\/products\/harvey-tool-937020-c3-square-end-mill-0-5mm-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
