What is true about double-cut files?

Double-cut files are designed with two sets of teeth cut at angles to each other, which allows them to remove material more quickly than single-cut files. The design increases the efficiency of the cut, making double-cut files ideal for shaping and roughing out materials. Their ability to remove more material in less time is particularly valuable in applications where aggressive material removal is required, such as in initial shaping processes or when working with harder materials.

While double-cut files excel at rapid material removal, they do not typically provide the same level of finish as single-cut files, which are better suited for finer work. Durability can vary based on the material and the specific usage of the file, but the primary factor distinguishing double-cut files is their ability to handle more aggressive cutting tasks rather than their overall lifespan. Polishing surfaces also typically requires different tools or types of files that focus on creating smooth finishes rather than removing material rapidly.
