Vertex C Type Boring Head

Here is a small head that will be in constant demand in any shop.
Note the wide base bearing surface that assures maximum rigidity even when the bar holder is in an off-set position. This wide base design is a recent Criterion innovation that increases bearing surfaces by 50% over the older models.
A choice of either 3/8inch or 1/2inch double hole bar holder with a 1/2inch cross hole is available.
The unit has a 7/8inch-20NC threaded back and also features a direct reading dial screw.
