It features a 3\/16 inch small end diameter, a 0.5 degree taper angle per side, and a 1-1\/4 inch length of cut. The ball end geometry allows smooth interpolation along curved and ramped surfaces. Three right-hand spiral flutes in a micrograin carbide substrate deliver sharp cutting action and consistent chip evacuation. This tool ships uncoated and is center-cutting, allowing plunge entry. Machinists and CNC programmers working in job shops, mold and die operations, and precision manufacturing will find this a direct-fit solution for tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish and semi-finish milling of hardened steels, alloy steels, stainless, aluminum, and non-ferrous materials where a tapered wall profile is required. The 1\/4 inch shank diameter fits standard ER and precision collet chucks. The 3 inch overall length provides reach into moderate-depth cavities without sacrificing rigidity. Typical applications include mold cavities, die inserts, complex part geometry on vertical and horizontal machining centers, and multi-axis CNC operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall end geometry for smooth 3D contouring and ramped surface finishing\u003c\/li\u003e\n\u003cli\u003e0.5 degree taper per side for precise tapered wall milling\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral design with 30 degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports direct plunge entry\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tapered ball end mill for standard 1\/4 inch collet and ER-style toolholding systems used in CNC vertical machining centers and multi-axis milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1\/4 inch shank fully and evenly in a clean, undamaged collet or toolholder and torque the retention nut to the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 0.5 degrees\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\u003eNose Radius\u003c\/strong\u003e: 3\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Ball\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\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\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: 12177559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732389822770,"sku":"12177559","price":113.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08d2e8d0b36485d31d6783bc54ee1d84_e021f669-fc52-4f2d-94b6-4a7c010a87ad.jpg?v=1788742326","url":"https:\/\/voomisupply.com\/products\/accupro-12177559-tapered-ball-end-mill-3-16-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
