Metalworking vices are available with different bases. These are listed below along with some information about each type.
Fixed bases
A vice with a fixed base attaches straight to the workbench and is stationary. A fixed base extends from the main body of the vice and commonly has bolt holes in order for it to be attached to the work surface.
All types of engineer’s vices are designed with a fixed base which bolts directly to a workbench.
Table vices are also available with a fixed base, however they are different to an engineer’s vice with a fixed base as these vices clamp instead of bolt to a workbench (see below for ‘clamp base’ vices). Despite this, the concept is still the same, as once they are clamped down they are then stationary and the vice body cannot be moved.
ADVANTAGES
DISADVANTAGES
Extremely reliable
Less risk of vice moving during work applications
Withstand heavy pressure from sawing or hammering
Less versatile
Can only be used in one position for working
Swivel bases
A vice with a swivel base can be rotated, allowing the vice to be placed in various positions while working.
A swivel base can rotate 360 degrees and then be locked in position at the best working angle.
A swivel base is usually fitted with two small lock nuts, one on either side, which controls the movement. To adjust the base, the nut is loosened by a small handle which allows the vice to be moved into the desired position. The nut is then tightened to keep the vice static.
Some types, such as multi-purpose vices, are designed with a swivel base attached which then bolts straight to the workbench…
…Whereas on other types, such as engineer’s vices, the swivel base is an extra feature that can be attached onto its fixed base.
Some table vices, including the hobby vice types, are also available with a swivel base, which allows them to rotate the vice body around once clamped to a workbench.
ADVANTAGES
DISADVANTAGES
Versatility
Allows user to place workpiece in a variety of positions while still in the vice’s hold
Can save user time
No need to constantly open and close jaws to reposition workpiece
Not as sturdy as a fixed base
Greater risk of vice moving during tough applications
Expensive
Clamp bases
Portable vices are usually equipped with an integrated clamp which attaches the vice to the edge of a worktop.
Instead of bolting to a workbench, as a fixed and swivel base does, it clamps, meaning it can be attached for working and then removed when needed.
All types of table vice are available with a clamp base.
ADVANTAGES
DISADVANTAGES
Portability
Versatility
Used in a variety of locations and situations
Can be used in the home for DIY purposes, or taken outside and used in a garage
Not as strong as a base that is bolted down
Can’t withstand holding heavy or large workpieces
Vacuum bases
Another type of base available is a vacuum base which holds onto a work surface by sucking onto it.
To mount to a workbench, the base has a lever which is rotated in an anti-clockwise direction to lock the vice onto the workbench. The lever can then be rotated clockwise to unlock the vice in order to remove it from the workbench.
The only vices available with this type of base are table vices, including the hobby and jeweller’s types.
ADVANTAGES
DISADVANTAGES
Portability
Easily moved and re-attached in any convenient space
Use both indoors and out
Not as secure as fixed or swivel base
Not capable of holding large or heavy workpieces
Suction may not last for a long period of time
Vice may have to be reapplied to a surface a number of times during long tasks
