TYPES AND USES
MACHINIST'S BENCH VISE
CLAMP BASE BENCH VISE
The machinist’s bench vise has rough jaws which pre-
vent the work from slipping. It has a swivel base, allow-
ing 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.
BENCH AND PIPE VISE
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 mate-
rial 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.
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 diame-
ter while cutting or threading.
