What M3316 does on the machine

A driven (live) tool holder that takes rotary drive from the turret.

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.

Do not order against the label alone. “VDI30” fixes the shank per DIN 69880, but pocket depth, clamping system and drive coupling still vary between machine builders. Send Mongtec your machine model and a photograph of the turret face — engineering checks M3316 against the actual turret drawing before anything is quoted. That check is free and takes one email.

Machines with a VDI30 turret

Mongtec publishes tooling pages for these machines with a declared VDI30 turret. Confirming your model here does not confirm M3316 as the article number — that still comes from engineering.

Frequently asked

What machines does the Mongtec M3316 fit?

M3316 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.

What speed and torque can M3316 run?

M3316 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.

What collet does M3316 take?

M3316 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.

Is a dimensioned drawing available for M3316?

Yes. Mongtec supplies the full dimensioned drawing for M3316 by email once an enquiry is open, so the drawing is matched to your actual machine and turret configuration rather than a generic sheet.

Get M3316 quoted

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 M3316 are supplied by email once the enquiry is open.
