With a 0.04-inch cutting diameter and a 3-flute geometry, this tool is built for tight-tolerance work in die, mold, and prototype machining environments. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces in small-diameter applications. An AlTiN coating extends tool life and improves heat resistance at elevated cutting speeds. The 1\/8-inch shank diameter makes it compatible with standard collet toolholding systems. Licensed machinists and CNC programmers working in jobshop and production environments will find this tool suited for fine-feature milling and slot work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for single-end use in CNC machining centers and manual mills where precision small-diameter cutting is required. The 13\/64-inch length of cut supports both shallow and moderate-depth slots and pockets. With centercutting capability and right-hand cutting and flute direction, it handles plunge and ramp entry operations. Its 2.5-inch overall length provides adequate reach for most standard setups without sacrificing rigidity. This tool is well suited to finish milling, contouring, and slotting passes in tool steel, hardened alloys, stainless, and aluminum.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating increases heat resistance and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip clearance with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables plunge and ramp entry without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/8-inch collet toolholders in CNC machining centers and manual mills requiring small-diameter solid carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before loading or removing the tool. Seat the shank fully in the collet to the recommended grip depth and torque the collet nut to the toolholder specification before running. Inspect the cutting edges under magnification before each use, as small-diameter carbide end mills are susceptible to edge chipping if dropped or improperly stored.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.2 inches (13\/64 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\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\u003eEnd Type\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\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: 12740-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51733238776114,"sku":"12740-C3","price":69.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8812d2b2470bfaa489e415e80bcb36_678e91ae-6ef1-4c4f-8705-5ccfbab3071c.jpg?v=1788753158","url":"https:\/\/voomisupply.com\/products\/harvey-tool-12740-c3-square-end-mill-0-04-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
