With a cutting diameter of 0.0394 inches (1.00 mm) and a length of cut of 0.1575 inches (4.00 mm), this micro-sized tool is built for fine detail work in hardened and exotic materials. The micrograin carbide substrate delivers rigidity and edge retention at small diameters where high-speed steel tooling fails. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This end mill is intended for use by machinists and CNC operators running precision machining centers or manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits small-feature milling in aerospace, medical device, mold and die, and general precision machining applications. The 0.0394 inch diameter makes it appropriate for micro-slot milling, fine contouring, and detail work in both ferrous and non-ferrous materials. The uncoated finish is suited for applications where coating buildup at micro diameters would affect dimensional accuracy. The regular length profile fits standard tool holders and collet systems without requiring extended-reach setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0394 inch (1.00 mm) cutting diameter for micro-precision milling operations\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention at small diameters\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry with 30-degree spiral helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry directly into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC spindle direction\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy in sensitive micro-diameter applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using collet or tool holder systems accepting a 0.1181 inch (3.00 mm) shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before tool changes. Seat the 0.1181 inch shank fully into the collet or tool holder and torque the retention system per the machine manufacturer specification. At micro diameters, runout control is critical  -  verify TIR with a dial indicator before committing to a cut to avoid 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: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm\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 (Micrograin)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743971967282,"sku":"12181224","price":29.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fb6e200d0e13b7df812fa008b8a8eed.jpg?v=1788852193","url":"https:\/\/voomisupply.com\/products\/accupro-12181224-square-end-mill-0-0394-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
