mainly used for milling or deburring operations. these are precision tools made of carbide (tungsten carbide), used to remove material from a surface, finish edges or shape parts made of metal, plastic or other hard materials. rotary files have a head with different shapes (cylindrical, spherical, conical, etc.) and are used for work requiring precision and wear resistance due to the properties of carbide, which is much stronger and more durable than traditional steel tools. these tools are widely used in fields such as industrial manufacturing, automotive, aerospace, and mechanical engineering.
