Built from micrograin solid carbide, this single-end tool features a 0.375 inch diameter, a 3-inch length of cut, and a TiCN (Titanium Carbonitride) coating that improves wear resistance and extends tool life in abrasive materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a 6-inch overall length, this is an extra-long reach tool suited for deep-cavity milling where standard-length end mills cannot reach. It is installed and operated by CNC machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is well suited for mold making, die work, and deep-pocket contouring on CNC machining centers and manual mills. The extra-long 6-inch overall length allows access to deep features without interference from the spindle or tool holder. The TiCN coating makes it appropriate for use on hardened steels, cast iron, stainless steel, and other ferrous materials where heat and abrasion are concerns. The 3\/8 inch shank diameter fits standard ER collets, end mill holders, and shrink-fit tooling commonly found in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.375 inch ball nose diameter for precise contour and 3D surface milling\u003c\/li\u003e\n  \u003cli\u003e3-inch length of cut for deep-reach profiling and cavity work\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length — extra-long configuration for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves hardness and reduces friction on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 3\/8 inch straight shank for standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3\/8 inch shank diameter end mill holder, ER collet chuck, or shrink-fit toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom professional. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before loading or removing the end mill. Seat the shank fully in the toolholder to the recommended insertion depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator after installation, as excessive runout will accelerate tool wear and degrade surface finish on extra-long configurations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute 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: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 12184539\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736277352754,"sku":"12184539","price":148.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d901f10bb6ab20061392c57835c9e3b.jpg?v=1788776945","url":"https:\/\/voomisupply.com\/products\/accupro-12184539-ball-end-mill-0-375-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
