Description: These end mills are made from ultra-fine grain cemented carbide material which ensures good milling, cutting performance and high work efficiency. They are of high strength, hardness and wear resistance and the cutting edges are quite sharp. There are 7 sizes which you can choose. Fine quality, these end mills are very good for processing on many materials including plastics, PCB and metal. Features: Made from ultra-fine grain cemented carbide material with good milling, cutting performance, ensuring high work efficiency. Have sufficient anti-bending strength, wear resistance, high hardness, high wear resistance and high strength. Sharp cutting edges, can be use for milling holes, grooves and edges on plates and the process will be smooth. Well polished surfaces are quite clean, neat, and there is no glitches or burrs on the shank. Many items or materials can be engraved such as circuit boards, metal, plastics, stainless steel and copper.
