Representative photographs of Mongtec driven tooling in this class — production units, not renderings. Shown as examples of the BMT75 family, not as a photograph of M5037 itself.
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.
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.
Mongtec publishes tooling pages for these machines with a declared BMT75 turret. Confirming your model here does not confirm M5037 as the article number — that still comes from engineering.

M5037 is built for the BMT75 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.
M5037 is rated to 4,000 rpm with 100 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.
M5037 takes ER40 collets. Collets and nuts are supplied separately; specify the shank diameters you intend to run and Mongtec quotes the collet set with the holder.
Yes. Mongtec supplies the full dimensioned drawing for M5037 by email once an enquiry is open, so the drawing is matched to your actual machine and turret configuration rather than a generic sheet.
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 M5037 are supplied by email once the enquiry is open.
