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.

Triangular Files
With three filing surfaces, these files work in spots others can't. They 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 file between saw teeth.
Black-oxide finish resists rust and clogging.

Needle Files for Stainless Steel
Remove material from stainless steel with little to no clogging. These files a have small tip that’s ideal for filing in slots, grooves, and other tight spots on intricate parts. And with a Swiss cut pattern, they’ll file with precision—they’re made to more exact measurements than files with an American cut pattern. 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. All files resist corrosion.
These files do not include a handle but do have a tang that fits into a handle. Length does not include the tang.

Smoothing and Polishing Stones
Maintain tools, molds, and dies. These stones can be used by hand or in power tools with a compatible holder. Choose the shape that best matches the contour of your work surface.
Aluminum–oxide stones abrade slowly to create a consistent surface. Also known as India stones. We recommend using a water-soluble or oil-based lubricant for stones that are not oil filled.
Novaculite stones have extremely fine grains that cut very slowly for the most control over finishing. Also known as Arkansas stones. Grit is approximate. We recommend using a water-soluble or oil-based lubricant.
