Files that have a crisscross tooth pattern are referred to as what?

Files with a crisscross tooth pattern are known as double cut files. This design is characterized by two sets of parallel teeth cut into the surface of the file, with one set crossing over the other at an angle. This unique pattern allows for faster material removal and provides a finer finish on the workpiece compared to single cut files, which have parallel teeth aligned in one direction.

Double cut files are particularly useful for working on harder metals and for achieving more refined shaping, while single cut files are typically used for softer metals or for finishing work. Curved files, on the other hand, are designed for specific applications involving curved surfaces, and flat files are simply flat in shape without the crisscross pattern. Thus, recognizing the distinguishing features of each type helps in choosing the right file for the job at hand.
