Files are graded according to the degree of fineness or coarseness and whether the teeth are single- or double-cut.

Single-cut files have rows of teeth cut parallel to each other at an angle of about 65 degrees from the centerline. Single-cut files are used for sharpening tools, finish filing and draw-filing. They are also the best tools for smoothing the edges of sheet metal.

Double-cut files have rows of teeth criss-crossed so teeth become diamond-shaped for fast cutting. Use double-cut files for quick removal of material and for rough work.

The fineness or coarseness of a file indicates tooth spacing and the number of teeth per inch. There are three basic dif- ferent grades: Ba$tard Cut, Second Cut and Smooth Cut. Ba$tard Cut has the fewest number of teeth per inch. Second Cut has more teeth per inch. Smooth Cut has the greatest number of teeth per inch. Varying degrees of coarseness or fineness are comparable only when files of the same length and shape are compared because coarseness of a file in- creases as the length from tip to heel increases. Which means a 6-inch file, either single or double-cut, has more teeth per inch than a 12-inch file.
