It features a 5-degree taper angle per side with a 1\/8 inch small end diameter and a 1\/16 inch nose radius, making it well suited for finishing passes where tight tolerances and smooth surface finishes are required. The 3-flute, right-hand spiral geometry with a 30-degree helix angle provides efficient chip evacuation while maintaining rigidity during cut. The uncoated micrograin carbide construction delivers consistent edge sharpness across a range of workpiece materials. Machinists and CNC programmers working in tool and die, mold making, and aerospace component shops are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC vertical machining centers and high-speed milling applications where tapered walls or drafted surfaces must be machined to finished dimensions in a single tool path. The ball end geometry allows it to blend smoothly into 3D contoured surfaces. The 7\/16 inch shank diameter and 4 inch overall length provide adequate reach for deep-cavity work without excessive deflection. It is centercutting, allowing plunge entry where required. Typical applications include mold cavities, core pins, electrodes, and complex aerospace profiles requiring consistent taper geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-degree taper angle per side for precise drafted wall geometry\u003c\/li\u003e\n\u003cli\u003e1\/8 inch small end diameter with 1\/16 inch nose radius for fine contour work\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a broad range of materials without thermal mismatch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard taper shank ball end mill for use in CNC machining centers and manual mills accepting a 7\/16 inch round shank with a collet or end mill holder.\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 powered down and locked out before loading or changing tooling. Seat the 7\/16 inch shank fully into the collet or end mill holder and torque the retention nut per the holder manufacturer specifications. Verify runout with a dial indicator before beginning the first cut to avoid premature edge wear or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 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\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: Ball\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: 12177644\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736626331954,"sku":"12177644","price":173.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1084456ec6dcc47ed82e2269b90fa32b.jpg?v=1788779040","url":"https:\/\/voomisupply.com\/products\/accupro-12177644-tapered-ball-end-mill-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
