TYPES AND USES
MACHINIST'S BENCH VISE
CLAMP BASE BENCH VISE
The machinist's bench vise has rough jaws which
prevent the work from slipping. It has a swivel base,
allowing the user to position the vise in a better
working position. Machinist's bench vises are usually
bolted to a work bench or table. They are used for
holding or clamping large, heavy objects.
The clamp base bench vise is a lightweight, portable
machinist's vise. It is attached to a table or bench with the
mounting clamp. It has rough jaws for holding material and
may have a swivel base. Clamp base bench vises are
used to hold light materials or in areas where a heavier
vise is not available.
BENCH AND PIPE VISE
PIPE VISE
The bench and pipe vise is a dual purpose vise. It
has rough jaws and a swivel base similar to the
machinist's bench vise. However, it also has built-in
pipe jaws. Bench and pipe vises are usually bolted to
a work bench or table. They are used for holding or
clamping heavy objects, holding pipe for cutting and
threading, and for forming and shaping metal.
The pipe vise is a special purpose vise designed to hold
round stock. It has hinged jaws which allow the user to
position the work and then lock it in place. Some pipe
vises have a section of chain instead of jaws for holding the
pipe. Pipe vises are usually bench mounted. They are
used to hold pipe from 1/8 inch to 8 inches in diameter
while cutting or threading.
