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 M9316 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 M9316 as the article number — that still comes from engineering.

M9316 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.
M9316 is rated to 6,000 rpm with 40 Nm of torque at a 1:1 drive ratio. The usable figure is whichever is lower: this rating or your machine's live-tool drive rating.
M9316 takes ER25 collets. Collets and nuts are supplied separately; specify the shank diameters you intend to run and Mongtec quotes the collet set with the holder.
Yes. Mongtec supplies the full dimensioned drawing for M9316 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 M9316 are supplied by email once the enquiry is open.
