It features a 1-degree taper angle per side, a 1\/4 inch small end diameter, and a 3-flute spiral configuration with a right-hand flute direction and 30-degree helix angle. The square end geometry and centercutting capability make it suited for slot milling, ramping, and profiling in ferrous and non-ferrous materials. Built from micrograin solid carbide, this tool delivers rigidity and edge retention in demanding cutting environments. It is installed by machinists and tool-and-die professionals working on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis tapered end mill is intended for applications where a precise taper wall is required, such as mold and die work, draft angle machining, and dovetail-adjacent profiling. The uncoated finish makes it a general-purpose option suitable for a range of workpiece materials where coating chemistry is not a requirement. With a 3\/8 inch shank diameter, it fits standard collet chucks and tool holders common in job shop and production environments. The 3.25 inch length of cut and 5 inch overall length allow reach into moderately deep cavities without requiring extended-reach tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-degree taper angle per side for controlled wall draft in mold, die, and cavity work\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry supports plunge entry and ramp milling operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for general-purpose milling across a broad material range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide tapered end mill for standard 3\/8 inch collet chucks and tool holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 3\/8 inch shank fully and evenly in the collet or tool holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut to avoid premature edge wear or tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\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\u003eSmall End Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: 12177463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744000475442,"sku":"12177463","price":196.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fa992a818f881315b011c04bd370f8c.jpg?v=1788852680","url":"https:\/\/voomisupply.com\/products\/accupro-12177463-tapered-end-mill-1-4-in-solid-carbide-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
