Files

Files are tools in the domain of mechanical engineering that are used in mechanical workshop applications. Files are the multipoint cutting tool that removes materials from a workplace. Files help to get the material to the failure point when there is a relative motion between them and the material. A file helps to cut, trim, reduce dimensions and provide surface finish to the material. The material is removed in the form of fine particles from the parent material.Files are primarily manually operated and are rarely implemented on machines. Material compatibility of files ranges from hard and soft metals to woods and plastics.
