What M5926 does on the machine

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.

Direct drive. The turret drive shaft couples straight into the tool spindle with no intermediate gear train. Fewer moving parts, less backlash and a stiffer path from the turret motor to the cutter — generally the better choice when surface finish and hole position matter.

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. “VDI40” 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 M5926 against the actual turret drawing before anything is quoted. That check is free and takes one email.

Machines with a VDI40 turret

Mongtec publishes tooling pages for these machines with a declared VDI40 turret. Confirming your model here does not confirm M5926 as the article number — that still comes from engineering.

Frequently asked

What machines does the Mongtec M5926 fit?

M5926 is built for the VDI40 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 M5926 run?

M5926 is rated to 5,000 rpm with 70 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 M5926 take?

M5926 takes ER32 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 M5926?

Yes. Mongtec supplies the full dimensioned drawing for M5926 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 M5926 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 M5926 are supplied by email once the enquiry is open.
