Tungsten carbide flat-end milling cutter is the most widely used cutter on CNC machine tools. Such an end milling cutter has the advantages of high hardness, wear resistance, high strength, good toughness, heat resistance and corrosion resistance. And it is mainly used for plane milling, groove milling, and copy milling, etc. Tungsten carbide flat-end milling cutters have cutter blades on the cylindrical surface and end surface, and they cut at the same time, or separately.

There are two common materials for end milling cutter: high-speed steel and tungsten carbide. Compared with high-speed steel, tungsten carbide has higher hardness and stronger cutting force, so that it can increase the speed and feed rate, thereby increasing productivity. Also, tungsten carbide can be used to process difficult-to-machine materials such as stainless steel and titanium alloy, but its cost is also higher. In addition, tungsten carbide cutters are prone to break when the cutting force changes rapidly.
