With a 0.04-inch cutting diameter and a 0.06-inch length of cut, this tool is built for fine detail work and tight-tolerance applications. The AlTiN coating provides elevated heat resistance and extended tool life under demanding cutting conditions. Three flutes with a 30-degree right-hand helix deliver efficient chip evacuation and a smooth finish. Licensed machinists and toolroom operators use this end mill for micro-milling passes where accuracy and edge integrity are critical.\u003c\/p\u003e\u003cp\u003eThis end mill fits small-part machining and micro-milling applications where a miniature cutting diameter is required. The 0.125-inch shank diameter allows it to seat in standard collets used across CNC machining centers and manual mills. At 1.5 inches overall length, it provides enough reach for typical cavity work without sacrificing rigidity. It is suited for production environments as well as prototype shops working in alloy steel, stainless, hardened materials, and similar substrates where AlTiN coating delivers performance advantages.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.04-inch cutting diameter for micro-milling and fine detail passes\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e3-flute geometry with 30-degree right-hand helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003e0.125-inch shank diameter fits standard collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement-style end mill for CNC machining centers and manual mills accepting a 0.125-inch collet or end mill holder.

Power down and lock out the spindle before seating or removing the tool from its holder. Use a properly sized collet and torque the drawbar or retention nut to the machine manufacturer's specification. At 0.04 inches diameter, even minor runout or side-loading can cause tool breakage, so inspect the collet and holder for wear before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.04 inches\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\u003eShank Diameter\u003c\/strong\u003e: 0.125 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\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\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\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 823040-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731125240114,"sku":"823040-C3","price":46.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18048af5bde92e723f116104ca380c6a_23ea4207-49fb-40b2-b9a6-3372b3af8bc2.jpg?v=1788727254","url":"https:\/\/voomisupply.com\/products\/harvey-tool-823040-c3-square-end-mill-0-04-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
