NICHOLSON 4" ROUND FILE SECOND CUT

FEATURES:

• Double-cut.
• File tapers toward the point making it adaptable on numerous size holes.
• Primarily used to enlarge and round out circular openings or concave surfaces.

(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.
