Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat cutting environments where tool life and dimensional accuracy matter. The 0.375-inch diameter with a 0.5-inch length of cut and 40-degree helix angle support aggressive material removal while maintaining surface finish quality. This tool is used by machinists and tool-and-die professionals running CNC vertical or horizontal milling centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for contour milling, profiling, and 3D surfacing operations in ferrous metals, stainless steels, and hardened alloys. The double-end configuration extends usable tool life by providing two cutting ends per shank. The right-hand cut and right-hand flute spiral direction make it compatible with standard spindle configurations. Stub length geometry keeps the tool rigid in tight-clearance setups where deflection must be minimized.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and extended tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eDouble-end design offers two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC milling machines accepting a 0.375-inch shank diameter collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. De-energize and lock out the machine spindle before changing tooling. Seat the shank fully and evenly in a matched collet or end mill holder and torque the retention system per the machine manufacturer's specifications. Confirm runout with a dial indicator before beginning a production cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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: 0.12 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: 12185378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729528422706,"sku":"12185378","price":118.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f41026a94b3d3981596e7922a100fc29.jpg?v=1788705778","url":"https:\/\/voomisupply.com\/products\/accupro-12185378-ball-end-mill-0-375in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
