Nos. 83 and 84 Thread Roll Holders

For "Bump" Thread Rolling From Front or Back Cross Slides!

B & S Thread Roll Holders are made in five different sizes to accommodate standard thread

rolls in a wide range of thread sizes. The holders are available in two styles, one for narrow and

one for wide thread rolls.

The design of the holders includes a swivel arrangement which can be adjusted to compensate

for any deflection in work caused by pressure of the rolls.

The end of the body holding the roll has one thin support so that the thread roll can be used

close to the collet. Rolls are mounted on long-wearing carbide pins.

Holders can be used on either the front or back cross slide by turning the tool over and merely

reversing the position of clamping bolt and swivel. A spacer is supplied with the wide holders

which accommodate rolls of two different widths.
