It features a 1-degree taper angle per side with a 0.0600-inch small end diameter, a 0.6000-inch length of cut, and a 3-flute geometry with a square end profile. The 30-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. Machinists and toolmakers install this end mill in CNC machining centers for contoured cavity work, draft angle milling, and miniature feature generation in mold, die, and precision component applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision machining operations in both production and prototype environments. Its miniature geometry makes it well-suited for mold-making, die work, medical device components, and aerospace detail parts where fine tapered walls or small-radius features are required. The solid carbide construction handles hardened steels, stainless, aluminum, and non-ferrous alloys in rigid, high-speed setups. The 3\/16-inch shank diameter and 3-inch overall length provide reach into deeper cavities while maintaining setup rigidity on compatible toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-degree taper angle per side for precise draft and contour milling\u003c\/li\u003e\n\u003cli\u003e0.0600-inch small end diameter enables fine detail and miniature feature work\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity, wear resistance, and dimensional stability\u003c\/li\u003e\n\u003cli\u003e3-flute square end geometry balances chip removal and finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle supports efficient chip evacuation in deep-cavity cuts\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter fits standard collet and toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option in the Harvey Tool Miniature End Mills - Tapered - Square series, compatible with CNC machining centers and manual mills equipped with a 3\/16-inch collet or toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with CNC tooling setup. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully and evenly in the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Confirm runout with a dial indicator before initiating a cut to protect the small-diameter tip from deflection or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 1 degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1680 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Tapered - Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 20660-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51736334106930,"sku":"20660-C6","price":127.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9990579dad9f43e8a378d0b929816313.jpg?v=1788777295","url":"https:\/\/voomisupply.com\/products\/harvey-tool-20660-c6-tapered-end-mill-solid-carbide-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
