Snap-Ring Pliers

Snap-Ring Pliers  Are used to remove and install snap rings. 

Many are designed to remove and install inward, as well as outward, expanding snap rings. 

Snap-ring pliers can feature serrated-tipped jaws for grasping the opening in the snap ring. 

Others are equipped with points, which are inserted into the holes in the snap ring.

Snap-ring pliers are also called lock-ring pliers and are designed to remove internal and external snap rings (lock rings).

Files  Used to smooth metal, files are constructed of hardened steel with diagonal rows of teeth. Files with a single row of teeth are

called a single-cut file.

A file with two rows cut at an opposite angle is called a double-cut file.

Files are available in a variety

of shapes and sizes from small

flat files, half-round and

triangular files.

Files come in many different shapes and sizes. Never use a file without

a handle.

Use Chalk

Often soft metal particles can become stuck in a file, especially when using it to file aluminum or other soft metals. Rub some chalk into the file before using it to prevent this from happening.

Safe Use of Files  Always use a file with a handle. Because files only cut when moved forward, a handle must be attached to pre-vent possible personal injury.

After making a forward strike, lift the file and return the file to the starting position; avoid dragging the file backward.
