About Files

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

Square Files

File slots, keyways, grooves, and corners with these four-sided tools. They have two sets of diagonal teeth. Files do not include a handle but do have a tang that fits into a handle. Length does not include the tang.

Rectangle	Half Round

Round	Square

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.

Wood Handle—Files with wood handles have a durable grip that's shaped to fit comfortably in your hand.

Precision File Sets

Made to exacting measurements, the files in these sets give you precise control over how much material you remove. Also known as Swiss-pattern files, they create more consistent finishes than American-pattern files. Use them for smoothing intricate parts and other applications where accuracy is key. All files are double cut, which means their surface has two sets of diagonal teeth. They remove material more quickly than single cut files, but you’ll need to use heavier pressure.
