Carbide Shank toolholders should be used when extra<br />

accuracy is required or when the bar length to bar diameter<br />

ratio exceeds 3:1.<br />

Holding device<br />

L<br />

3 x D<br />

Minimum length<br />

The overhang to bar diameter ratio should be as small<br />

as possible to eliminate the chance of chatter (vibration).<br />

The minimum length inside a holding device should be<br />

3 times the diameter of the bar shank.<br />
