■ Work to be accomplished, such as roughing or finishing, will determine type of teeth and coarseness for each application
■ Most American pattern files are available with 3 grades of cut: bastard-cut, second-cut and smooth-cut
■ Swiss pattern files are available in seven cuts: No. 00, 0, 1, 2, 3, 4, and 6
■ The degree of coarseness is greater in longer files, but differences between bastard, second and smooth are proportionate

■ Area to be filed will determine specific cross-section (round,
square, flat, etc.) to be used
Kinds of Teeth
SINGLE-CUT
RASP-CUT
■ Single set of parallel, diagonal rows of teeth
■ Single-cut files are often used with light pressure to produce
■ Series of individual teeth formed by a single-pointed tool
■ Produces a rough cut that is used primarily on wood, hooves,
a smooth surface finish or to put a keen edge on knives,
shears or saws
aluminum and lead
MAGICUT®
DOUBLE-CUT
■ Single cut teeth divided by angular serrations into shorter
cutting edges, which free themselves readily from chips
and perform roughing and smoothing at the same time
■ 2 sets of diagonal rows of teeth
■ Second set of teeth cut in opposite diagonal direction and on
CURVED-CUT
top of the first set
■ First set of teeth is known as the overcut, second is upcut
■ Upcut is finer than overcut
■ Double-cut file is used with heavier pressure than the
single-cut and removes material faster from the workpiece
■ Teeth arranged in curved contours across the file face
■ Curved-cut file is normally used in automotive body shops for
smoothing body panels
