Built from micrograin carbide, the tool holds a sharp edge longer than standard carbide grades and supports tighter tolerances in finish passes. The 1-degree taper per side produces a consistent draft angle, while the 3-flute spiral geometry with a 30-degree helix balances chip evacuation with surface finish. The square end configuration allows flat-bottom cuts. This tool is installed and operated by machinists and tool-and-die professionals using CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis tapered end mill is suited for die and mold work, engraving, and finish milling of angled walls in both prototype and production environments. The small end diameter of 1\/16 inch allows access to narrow features and fine detail work where larger tools cannot reach. The 1\/2-inch length of cut provides adequate flute engagement for shallow-to-moderate depth passes. The 1\/8-inch shank fits standard collets and end mill holders common in CNC and manual setups. Applications include ferrous and non-ferrous metals, graphite electrodes, and engineering plastics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life and edge retention\u003c\/li\u003e\n\u003cli\u003e1-degree taper per side for accurate draft-angle and contour milling\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral with 30-degree helix balances chip flow and finish quality\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable  -  allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSquare end geometry for flat-bottom slot and pocket floors\u003c\/li\u003e\n\u003cli\u003eUncoated finish suited for applications where coating compatibility or regrinding is a consideration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide tapered end mill for use in standard 1\/8-inch collet chucks, end mill holders, and ER-series collets on CNC machining centers and manual vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable machine safety procedures. Seat the 1\/8-inch shank fully into the collet or end mill holder and torque the retention hardware to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut. Carbide is brittle  -  avoid side impacts during handling and storage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 1 degree\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 12177448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742165205298,"sku":"12177448","price":50.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c37873f7748a3a7cac9209673a4c32cb.jpg?v=1788835708","url":"https:\/\/voomisupply.com\/products\/accupro-12177448-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
