Built from micrograin solid carbide, this tool offers the rigidity and edge retention required for hardened steels and abrasive materials. The ball end geometry produces a 1\/32 inch nose radius, making it well suited for finishing passes on 3D surfaces. With a 5-degree taper per side, a 1\/16 inch small end diameter, and a 1-1\/2 inch length of cut, this end mill is engineered for deep-reach finishing where dimensional accuracy is critical. Machinists and tool and die professionals install this type of tooling on CNC machining centers and milling machines.\u003c\/p\u003e\u003cp\u003eThis tapered ball end mill is intended for use in milling operations that require precise contouring, core and cavity work, and intricate profile cutting. The 5-degree taper per side geometry is commonly applied in die sinking, mold making, and aerospace component work where drafted wall features are required. The 3\/8 inch shank diameter provides a secure grip in standard collet and end mill holders. The uncoated micrograin carbide construction suits applications where tool geometry alone drives performance or where coatings may interfere with surface finish requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-degree taper per side for accurate drafted wall and cavity milling\u003c\/li\u003e\n\u003cli\u003eBall end geometry with 1\/32 inch nose radius for smooth 3D surface finishing\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention in demanding materials\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design with right-hand flute direction for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where bare carbide is preferred\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual milling machines accepting a 3\/8 inch shank diameter end mill holder or collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with CNC or manual milling operations. Ensure the machine spindle is fully stopped and the control is in an estop or locked-out state before loading or changing tooling. Seat the 3\/8 inch shank fully into a matched collet or end mill holder and torque the retention nut to the tool holder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout on small-diameter tooling accelerates premature wear and breakage.\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: Ball\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\u003eSmall End Diameter\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 1\/32 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\u003eOverall Length\u003c\/strong\u003e: 3 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\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 12179311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742721409330,"sku":"12179311","price":138.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2edfb10f956bf82cda45d211ef737350.jpg?v=1788839074","url":"https:\/\/voomisupply.com\/products\/accupro-12179311-tapered-ball-end-mill-solid-carbide-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
