Representative photographs of Mongtec driven tooling in this class — production units, not renderings. Shown as examples of the VDI30 family, not as a photograph of M4616 itself.
The driven spindle points at 90° to the lathe spindle, along the X axis. This is the configuration for cross drilling, cross tapping and slotting on the outside diameter.
Radial-disc mounting — mounts to the turret's radial disc rather than a standard station.
Gear ratio 1:1 — tool spindle speed equals turret drive speed. The direct relationship makes speeds and feeds straightforward to calculate from the machine's live-tool rating.
Mongtec publishes tooling pages for these machines with a declared VDI30 turret. Confirming your model here does not confirm M4616 as the article number — that still comes from engineering.

M4616 is built for the VDI30 turret interface. Because VDI shank dimensions follow DIN 69880, but turret pocket depth, clamping system and drive coupling still vary between machine builders. Send Mongtec your machine model and a photo of the turret face and engineering confirms the fit before anything is quoted.
Yes. Mongtec supplies the full dimensioned drawing for M4616 by email once an enquiry is open, so the drawing is matched to your actual machine and turret configuration rather than a generic sheet.
Send the machine model, the turret station you want to use and the tools you intend to run. Anything you do not know, Mongtec works out from the machine model — an incomplete enquiry is still worth sending. Dimensioned drawings for M4616 are supplied by email once the enquiry is open.
