With a 0.018-inch cutting diameter and four flutes, this end mill delivers clean, accurate cuts at micro scales. The AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Centercutting geometry allows plunge entry directly into the workpiece. This tool is built for machinists and toolmakers running small-diameter work on CNC mills and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling fine features, slots, pockets, and contours in hardened steels, stainless steel, titanium, and other demanding materials where a micro-diameter tool is required. The 0.125-inch shank diameter fits standard collets commonly found on CNC machining centers and high-speed spindles. The 1.5-inch overall length provides enough reach for most shallow-feature applications without sacrificing rigidity at this diameter. Right-hand cut and right-hand flute direction are standard for conventional CNC milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.018-inch cutting diameter for micro-scale milling operations\u003c\/li\u003e\n\u003cli\u003eFour-flute solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC compatibility\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 0.125-inch shank diameter via ER collet or equivalent toolholding system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator familiar with micro-diameter tooling. Secure the shank fully in a collet or toolholder to the manufacturer-specified grip length before running. At this diameter, excessive runout or improper speeds and feeds will result in immediate tool breakage. Always verify spindle runout and use appropriate chip load calculations for micro end mills before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.018 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.054 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\u003eOverall Length\u003c\/strong\u003e: 1.5 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\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: 73018-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732007846194,"sku":"73018-C3","price":60.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b439e4d9750d2d519b94c7aaf8826d59_3a9c7a6f-b37a-4a67-9630-a934c3a9067b.jpg?v=1788738008","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73018-c3-square-end-mill-0-018-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
