The choice of a double cut file is associated with its efficiency in rapid stock removal due to its unique tooth configuration. A double cut file features intersecting teeth arranged in one direction and then again in the opposite direction, which allows it to remove material more quickly than files with a single cut. The design helps to create a more aggressive biting action on the surface of the material being worked on.

This capability makes the double cut file particularly useful for processes that demand quick material removal, such as initial shaping or rough finishing of metal surfaces, where a significant amount of material needs to be removed in a short amount of time. The extra cutting edges provided by the double cut setup significantly contribute to this enhanced performance.

In contrast, other files, such as single cut and round files, are typically used for finer work, shaping, or smoothing, and therefore do not facilitate rapid stock removal to the same extent. Flat files can also be effective but are traditionally more suited for finishing operations rather than aggressive material removal. Thus, the double cut file stands out as the most efficient choice for tasks that require rapid stock removal.
