its shape or size, or when a vise is not available.
Clamps are generally
used for light work.
b. Types of Vises.
(1) Machinist's Bench Vise. A machinist's bench vise (figure 40) is
a large steel vise with rough jaws that prevent the work from slipping.
Most of these vises have a swivel base with jaws that can be rotated, while
others cannot be rotated.
A similar light duty model is equipped with a
cutoff. These vises are usually bolt-mounted onto a bench.
(2) Bench and Pipe Vise.
The bench and pipe vise (figure 40) has
integral pipe jaws for holding pipe from 3/4 inch to 3 inches in diameter.
The maximum working main jaw opening is usually 5 inches, having a jaw width
of 4 to 5 inches.
The base can be swiveled to any position and locked.
These vises are equipped with an anvil and are also bolted onto a workbench.

TYPE OF VISES.
(3) Clamp Base Bench Vises.
The clamp base bench vise (figure 40)
usually has a smaller holding capacity than the machinist's or bench and
pipe vises and is clamped to the edge of a bench.
Holding capacity is
generally 1 1/2 to 3 inches. These vises normally do not have pipe holding
jaws.
