Precision Tool Vice

precision-tool-vice-002I have a heavy duty 3″ wide Soba machine vice, great for general use. However, I often want a small precise vice to hold some of the smaller parts that I make.

After much searching I ended up on – a very easy company to deal with who deliver promptly.

The dimensions are:

Jaw width: 50mm
Jaw depth: 25mm
Jaw opening: 65mm
Overall length: 140mm
Height: 50mm

precision-tool-vice-003The vice is tightened with a caphead bolt that pulls the jaws at 45° so bring them together and tight onto the rails.

This action means that there is no tendency for the jaws to rise away from the bed rails as the final tightening pressure is applied.

The vice can be clamped down using the holes in the side of the main frame or using clamps on either end.

A scooped out recess at either end allows the vice to be clamped down to the table.

This is awkward at first to use, especially when you have clamped the vice to the milling table and don′t really want to release it.

A great aspect of this vice is that it is ground square so you can align it to the milling table with an engineers square.

Price: approx £39 for this 50mm wide jaw version (2010 price)


This is a precision vice and the action of the jaws being pulled at 45° is just superb when you are working to very tight tolerances.

There are a number of different ways to hold or clamp a workpiece – see our page on workholding.
