Built from micrograin carbide stock and finished with an AlTiN (Aluminum Titanium Nitride) coating, this tool delivers heat resistance and extended tool life in ferrous and hard alloy machining applications. The 3-degree taper per side generates a consistent draft angle along the flute length, while the ball end profile handles contoured and 3D surface work. Two spiral flutes with a 30-degree helix angle provide efficient chip evacuation. This tool is installed and operated by machinists and CNC programmers in job shop, tool and die, and production machining environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finishing and semi-finishing passes on tapered pockets, mold cavities, and contoured part features. The 1\/4-inch small end diameter and 1\/4-inch length of cut make it appropriate for fine detail work in confined geometry. The 3\/8-inch shank diameter accepts standard ER or end mill holders in most machining centers. The 6-inch overall length provides reach for deep-cavity applications without requiring extended-reach toolholders in typical setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-degree taper per side for consistent draft angle on tapered pockets and mold features\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating enhances heat resistance and tool life in ferrous and high-hardness materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBall end profile supports 3D contouring and blended surface finishes\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction, centercutting capable, 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides deep-cavity reach with a standard 3\/8-inch shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool compatible with standard end mill holders and ER collet chucks accepting a 3\/8-inch shank diameter in vertical and horizontal CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC setup technician. Secure the 3\/8-inch shank in a properly sized collet or end mill holder and torque to the toolholder manufacturer's specification before spindle operation. Confirm runout with a dial indicator prior to cutting, as excessive runout on a tapered profile tool will accelerate wear and degrade surface finish. Do not exceed the rated depth of cut for the 1\/4-inch length of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 1\/8 inch (0.1250 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\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12179397\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733620850994,"sku":"12179397","price":190.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb044c959c74bc28a59699d55bb77a12.jpg?v=1788757012","url":"https:\/\/voomisupply.com\/products\/accupro-12179397-tapered-ball-end-mill-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
