What M9407 does on the machine

The driven spindle points along the Z axis, parallel to the lathe spindle. This is the configuration for face drilling, face tapping and end milling on the part face.

Through-coolant. Coolant is routed inside the holder and delivered at the cutting edge through the collet and tool. For deep-hole drilling and tapping in stainless or titanium this is usually the difference between a tool that survives the cycle and one that does not.

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. “BMT45” identifies the nominal turret class, but BMT is an industry de-facto standard — it is not published by ISO or DIN. Bolt circle, key position and drive coupling can differ between machine builders at the same nominal size. Send Mongtec your machine model and a photograph of the turret face — engineering checks M9407 against the actual turret drawing before anything is quoted. That check is free and takes one email.

Machines with a BMT45 turret

Mongtec publishes tooling pages for these machines with a declared BMT45 turret. Confirming your model here does not confirm M9407 as the article number — that still comes from engineering.

Frequently asked

What machines does the Mongtec M9407 fit?

M9407 is built for the BMT45 turret interface. Because BMT is an industry de-facto standard rather than an ISO or DIN published standard, bolt circle, key position and drive coupling can differ between machine builders even at the same nominal size. 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 M9407 run?

M9407 is rated to 8,000 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 M9407 take?

M9407 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 M9407?

Yes. Mongtec supplies the full dimensioned drawing for M9407 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 M9407 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 M9407 are supplied by email once the enquiry is open.
