Nano Coated Carbide Tungsten Steel Milling Cutter with 4 Edges used for CNC Milling

End Mill Features 1.The milling cutter surface is coated with nACo nano coating, which allows for direct rough to finish machining of heat-treated materials with a hardness below HRC65. This reduces tool changes and improves machining efficiency. 2.The milling cutter demonstrates strong versatility, suitable for machining various materials such as alloy steel, hardened steel, stainless steel, cast iron, copper alloys, plastics, and more. Whether it is rough or precision machining, it provides excellent machining performance and high machining accuracy. 3.The milling cutter is made from 0.2-0.4um ultra-fine tungsten steel raw material, providing higher wear resistance and strength. 4.The design features a large chip flute, with the spiral groove being ground as a whole, preventing tool sticking and facilitating rapid discharge of iron chips. 5.The design incorporates a large core diameter, ensuring sufficient space for chip evacuation. This greatly enhances the tool's rigidity and anti-
