Built from solid carbide with an AlTiN coating, it runs at 1 mm (0.0390 inch) cutting diameter with a 0.058-inch length of cut and a 1\/8-inch shank diameter. The 4-flute geometry and 30-degree helix angle promote smooth chip evacuation and consistent surface finish. Overall length is 1.5 inches. The centercutting design allows plunge entry, adding versatility in die work, mold machining, and general contouring. Machinists and tool-and-die professionals working on small-feature components are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for small-feature milling operations on hardened steels, stainless alloys, cast iron, and other difficult-to-machine materials where AlTiN coating provides thermal resistance and extended tool life. Its compact 1 mm diameter makes it appropriate for slotting, profiling, and contouring narrow channels or fine detail geometry in mold cavities, medical components, and precision mechanical parts. The 1\/8-inch shank fits standard collet chucks used on CNC machining centers and high-speed spindles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 mm cutting diameter with 0.058-inch length of cut for fine-feature work\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature resistance and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e4 flutes with 30-degree right-hand helix for efficient chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 1\/8-inch shank diameter for common collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/8-inch collet chucks on CNC machining centers and high-speed milling spindles.

Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Seat the shank fully into the collet and torque the collet nut to the spindle manufacturer's specification. At 1 mm diameter, tool runout is critical — verify TIR with a dial indicator before production runs to prevent premature tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 mm (0.0390 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.058 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\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 14039-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51729190977842,"sku":"14039-C3","price":49.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21086ce8f45e729f8711684a4ab921dd.jpg?v=1788701721","url":"https:\/\/voomisupply.com\/products\/harvey-tool-14039-c3-square-end-mill-1mm-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
