4IN. MILL BASTARD FILE

Very adaptable file that can be used for a multitude of applications such as sharpening various types of tools and saws, draw filing, lathe work and general shop use.

FEATURES:

• Single-cut on edges and sides.
• File tapers toward the point for detail.
• Two square edges.

(SINGLE-CUT – Single set of parallel, diagonal rows of teeth. Often used with light pressure to produce a smooth surface finish or to put a keen edge of knives, shears or saws.)

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.
