In addition, some manufacturers offer rough files (coarser than bastard cuts, with about 16 teeth per inch) and dead smooth files (very fine cut with about 100 teeth per inch).įiles are available in different shapes. ![]() Smooth files have 60 teeth per inch, second-cut files 36 teeth per inch and bastard files 26 teeth per inch. Files are generally graded in three categories of coarseness smooth, second cut or medium-smooth, and bastard cut or medium-coarse. Double-cut files clear material faster than the single-cut files, but they create a rough surface that must be smoothed with the single-cut file.Ī file will be either coarse or smooth, depending upon the number of teeth per inch and the spacing between rows of teeth. The teeth form a diamond pattern across the face of the tool. Double-cut files have teeth that crisscross at opposing angles. Single-cut files have rows of teeth cut in one direction only - usually at a 65-degree angle to the center line. Tooth configuration refers to whether a file is single- or double-cut.
