What M9046 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. “VDI25” 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 M9046 against the actual turret drawing before anything is quoted. That check is free and takes one email.

Machines with a VDI25 turret

Mongtec publishes tooling pages for these machines with a declared VDI25 turret. Confirming your model here does not confirm M9046 as the article number — that still comes from engineering.

Frequently asked

What machines does the Mongtec M9046 fit?

M9046 is built for the VDI25 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.

Is a dimensioned drawing available for M9046?

Yes. Mongtec supplies the full dimensioned drawing for M9046 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 M9046 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 M9046 are supplied by email once the enquiry is open.
