What is a flat end mill

Platform end mills are mainly used for fine or rough milling, groove milling, removal of a large amount of blanks, and fine milling of small horizontal planes or contours. In this case, the material of the milling cutter is cemented carbide end mill. Compared with the milling cutter made of high-speed steel, it has high hardness and strong cutting force, which can increase the speed and feed rate, improve productivity, and process difficult-to-machine materials such as stainless steel and titanium alloy. But the cost is higher, and the tool is prone to breakage in the case of rapid alternating cutting forces.
