About Files

Choose files by texture—coarse for quick and heavy removal of material, extra fine for precision and a smooth finish.

File Sets

Keep multiple files on hand for workpieces of different shapes and sizes.

All sets include American-pattern files, also known as machinists' files.

3 Pieces


	Rectangle

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

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

Single-Cut Face with Chip Breaker—Speed up reaching a fine finish. They remove material as quickly as double-cut files while leaving behind a smooth finish at the same time. They have single-cut teeth divided by diagonal cutting edges that act as chip breakers—the chip breakers rough the surface while the single-cut teeth smooth it.

Painted Steel Handle—Files with painted steel handles have a single-piece construction.

Rubber Handle—Files with rubber handles have a cushioned, comfortable grip.

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