Description

For 200 years, PFERD has been manufacturing files of a world-renowned high quality. The experience gained over many years as a manufacturer is constantly used for the development of PFERD files. Application-oriented file shapes and cuts for industry and crafts guarantee good economic value. Even after long use, PFERD files achieve high stock removal rates and an excellent surface quality.

Diamond files and sheets are used particularly successfully for tasks where conventional files fail due to the hardness of the workpiece material.

Diamond needle files are designed for general use in tool making. Diamond needle files in extra slim design are ideal for work on deep-set and narrow contours.
