Features: These milling cutters are made of tungsten carbide steel with good milling, cutting performance, ensuring high work efficiency. They 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, hardware parts, plastics, copper and stainless steel.
