Double-cut teeth on both faces of these tapered, rectangular files make aggressive cuts. Each face has two crisscrossing sets of diagonal rows of teeth that slant in opposite directions to remove material more quickly and leave a rougher finish than single-cut teeth. Tapered files get steadily narrower from the heel to the point for filing in wider or narrower bands.

Double-cut teeth on both faces of these straight, rectangular files make aggressive cuts. Each face has two crisscrossing sets of diagonal rows of teeth that slant in opposite directions to remove material more quickly and leave a rougher finish than single-cut files. Also known as hand files, straight (blunt) files are the same width from heel to point to produce uniform filing anywhere along the length.

Single-cut teeth on both faces of these tapered, rectangular files run in diagonal rows and one direction to sharpen edges and produce smooth surface finishes. Tapered files get steadily narrower from the heel to the point for filing in wider or narrower bands.

Double- and single-cut rectangular files provide two different cut styles for rapid stock removal and smoothing with a single tool. Also known as handy files, their double-cut face has two crisscrossing sets of diagonal rows of teeth that slant in opposite directions to remove material more quickly and leave a rougher finish than the single-cut face. The single-cut face has one set of diagonal rows of teeth running in the same direction to sharpen edges and produce smooth surface finishes.

Short, angular teeth cover both faces of these tapered, rectangular files with serrated cutting edges that rapidly remove material, leave a smooth finish, and clear chips to prevent clogging. Also known as chip breaker files, they taper in width toward the point for filing slots.
