It features a 0.138 inch (3.50 mm) mill diameter with a 2-flute, right-hand spiral configuration and a 40-degree helix angle for efficient chip evacuation. The cutting edges are finished with a TiCN (Titanium Carbonitride) coating to extend tool life and reduce friction at elevated cutting speeds. With a stub-length profile and micrograin carbide construction, this end mill delivers rigidity and wear resistance in demanding applications. It is a single-end tool sold individually.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is suited for contouring, profiling, and slotting operations on ferrous and non-ferrous metals, hardened steels, and alloys. The 0.138 inch diameter and 0.2756 inch (7.00 mm) length of cut make it appropriate for fine-detail work and tight-tolerance finishes in CNC machining centers and manual mills. The 4 mm shank diameter fits standard collet and tool holder systems. A 50 mm overall length keeps the tool compact for reduced deflection in close-clearance setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.138 inch (3.50 mm) ball nose diameter for fine contouring and profiling\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for improved hardness, lubricity, and tool life on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix for effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStub-length design minimizes deflection in close-clearance cuts\u003c\/li\u003e\n  \u003cli\u003eSingle-end, 2-flute configuration suited for plunge and contour milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines equipped with collet or toolholder systems accepting a 4 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or unloading tooling. Verify collet bore size matches the 4 mm shank diameter before tightening to avoid runout or slippage. Consult machine and tooling documentation for appropriate speeds and feeds based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.138 inches (3.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.2756 inches (7.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\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: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 12184089\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732024688946,"sku":"12184089","price":62.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ce8911c7cf3e007122750e3dd02027d.jpg?v=1788738286","url":"https:\/\/voomisupply.com\/products\/accupro-12184089-ball-end-mill-0-138-in-2-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
