VDI-60 Rotary Holders with CAT 40 tooling
We offer a unique solution for heavy duty milling / drilling performance for VDI-60 users. Our rotary tool holders feature CAT 40 taper tool connection instead of the commonly used collet system to achieve unparalleled rigidity. Now you can use your regular machining center tooling in your turning center!


The VDI-60 holders accept the CAT 40 tool holder and use a lock-bolt to manually clamp the pull studs.


Pull studs and lock-bolts are delivered with the tool holder kit.
