Machinist Files

• Work to be accomplished, 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 • The degree of coarseness is greater in longer files, but differences between bastard, second and smooth are proportionate

• Length is measured exclusive of tang, from point to heel, unless otherwise specified • Desired stroke length, type of material and size will determine length required

Kinds of Teeth

Half Round Files - Boxed

Nucut® Wavy Tooth

Single-cut

• Backs of all 4” and 6” files are single-cut • Backs of all half-round smooth files are single-cut • Flat sides of all half-round files are double-cut • Pipeliner file is single-cut on back and flat sides • Boxed

• Used on concave, convex and flat surfaces • Rounded on 1 side, flat on opposite

• Single set of parallel, diagonal rows of teeth • Single-cut files are often used with light pressure to produce a smooth surface finish or to put a keen edge on knives, shears or saws

• Coarse to fine to extra fine tooth spacing enables material to be removed faster and smoother without “chatter” • File lasts longer due to reduced stress on the file teeth

• Backs of all half-round bastard files are double-cut • Backs of all half-round second cut files longer than 6” are double-cut

• Removes material faster while creating a smooth finish • The combination of coarse teeth and a “chip breaker” groove cut into the file allows this product to do the work of a flat file and a mill file

• 2 sets of diagonal rows of teeth • Second set of teeth cut in opposite diagonal direction and on top of the first set • First set of teeth is known as the overcut, second is known as 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
