Featuring a 0.3281-inch (21\/64) cutting diameter and three flutes, this single-end tool delivers efficient chip evacuation and smooth finish cuts in contoured and profiled surfaces. The 40-degree helix angle promotes aggressive cutting action while reducing chatter. Micrograin carbide construction provides the hardness and wear resistance required for demanding cuts in ferrous and non-ferrous materials. This tool is used by machinists and tool-and-die professionals working on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis ball end mill is well suited for 3D profiling, slotting, and contour milling in production and job-shop environments. The 0.875-inch length of cut allows access into moderate-depth pockets and curved surfaces. With a 3\/8-inch shank diameter and 2.5-inch overall length, it fits standard ER and side-lock collet systems commonly found on vertical machining centers. The uncoated finish makes it a reliable choice for use with cutting fluids on aluminum, steel, and similar materials where coating adhesion is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.3281-inch (21\/64) ball nose cutting diameter for accurate radius profiling\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral geometry with 40-degree right-hand helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003e0.875-inch length of cut supports moderate-depth pocket and contour work\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 3\/8-inch shank for broad collet compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with flood and mist coolant strategies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for CNC vertical machining centers and manual mills accepting a 3\/8-inch straight shank end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling procedures. Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before inserting or removing the tool. Use a calibrated torque wrench and appropriate collet nut wrench when seating the shank in an ER collet chuck to achieve proper clamping force. Confirm runout with a dial indicator before beginning production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3281 inches (21\/64)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches (7\/8)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 12184364\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732665565490,"sku":"12184364","price":56.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/616e346c5778791a57efed8b8d585fa1.jpg?v=1788745504","url":"https:\/\/voomisupply.com\/products\/accupro-12184364-ball-end-mill-0-3281-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
