Holders<br />
Miniature square and round toolholders are designed for use on automatic<br />
lathes for the optical and other precision industries. They can be used for<br />
both external and internal threading, as follows:<br />
<strong>Thread</strong> ER EL IR IL<br />
Insert ER EL IR IL<br />
Holder LH RH RH LH<br />
The above toolholders are for RH inserts. For LH inserts, add LH to the toolholder’s ordering code.<br />
