What M8007 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.

External coolant. Coolant is delivered to the cut from outside nozzles. Suitable for general drilling, tapping and milling where chip evacuation is not the limiting factor.

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 M8007 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 M8007 as the article number — that still comes from engineering.

Frequently asked

What machines does the Mongtec M8007 fit?

M8007 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 M8007 run?

M8007 is rated to 8,000 rpm with 25 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 M8007 take?

M8007 takes ER20 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 M8007?

Yes. Mongtec supplies the full dimensioned drawing for M8007 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 M8007 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 M8007 are supplied by email once the enquiry is open.
