Used for angles less than 90° for cleaning corners, filing cutters and taps. The triangular shape (each side at 60° angles from one another) enables this file to get into corners the others cannot.
FEATURES:
Double-cut.
Cut to the point.
Sharp corners are slightly set and cut.
(DOUBLE-CUT – Two sets of diagonal rows of teeth. Second set (upcut) cut in the opposite direction and on top of the first set (overcut). Upcut is finer than overcut. Double-cut file is used with heavier pressure than the single-cut and removes material faster from the workpiece.)
COARSENESS:
Work to be accomplished, roughing or finishing, will determine teeth and coarseness for each application.
Most American pattern files are available with 3 grades of cut: bastard cut, second cut, and smooth cut.
The degree of coarseness is greater in longer files, but differences between bastard, second, and smooth are proportionate.
