The driven or live tool holder is an accessory for CNC turning centers with motorized turret to perform drilling, milling and tapping jobs. With driven tools you can finish machine a complex work piece in one setup without re-chucking the part thus maintaining accuracy and concentricity.

Our supplier can offer a wide range of rotary tool holders, and also build special driven tool holders to customer request. See just a few examples below:

Our driven tool holders are usually equipped with ER collets, but we also offer Weldon DIN 1835 or KM Kennametal mandrels.

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.

The mass of these tool holders are shown below where the VDI-60 is pictured next to a common VDI-30 holder:
