About Files

Files, also known as American-pattern and machinists' files, are used to remove material quickly.

Precision files, also known as Swiss-pattern files, are made to exacting measurements to ensure smoothness and are useful for finishing delicate and intricate parts.

Files do not include a handle but do have a tang that fits into a handle. Length does not include the tang.

Double Cut—Surface has two sets of diagonal teeth and is often used with heavier pressure than single cut for rapid material removal.

Single Cut—Surface has one set of diagonal teeth and is often used with light pressure to slowly remove material and sharpen tool-cutting surfaces.

Tapered

Double Cut

Single Cut

Double-cut tapered files are also known as flat files.

Single-cut tapered files with teeth on the edges are often used to sharpen milling and circular saws. Also known as mill files.

Black-oxide finish resists rust and clogging.

No need for a separate handle—these files have one built in. Length does not include the handle.

Double Cut—Surface has two sets of diagonal teeth and is often used with heavier pressure than single cut for rapid material removal.

Single Cut—Surface has one set of diagonal teeth and is often used with light pressure to slowly remove material and sharpen tool-cutting surfaces.

Edges with no teeth protect adjacent surfaces when filing.

Files with steel handles have a single-piece construction. Files with rubber-coated plastic handles have a cushioned, comfortable grip.

Nonsparking Rectangular Files

Made from beryllium copper, these files won’t create sparks as you smooth and shape workpieces. They’re also nonmagnetic. They help you meet OSHA requirements for using nonsparking tools in areas where flammable vapor or combustible residue are present. These files have two sets of diagonal teeth for rapid material removal. The handle is coated in rubber to cushion your grip. Length does not include the handle.

Integrated-Handle Half-Round Files

Double Cut

No separate handle needed—these files shape concave, convex, and flat surfaces right out of the box. The handle is rubber coated for a comfortable grip. Since they’re double cut with two sets of diagonal teeth, you can put more pressure on them than single-cut files for quicker filing. Length does not include the handle.

Files with a black-oxide finish resist rust and clogging.
