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.
The output is not a collet nut. M0407 ends in a PSC32 polygon taper coupling, so cutting tools are changed as complete PSC32 assemblies — the same coupling family the machine may already use on its static stations.
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.
PSC32 is a polygon shank cone to ISO 26623 — an open international standard. The C3 designation refers to the same nominal size under the Coromant Capto name. A PSC32 output lets one driven station carry drills, mills, boring bars and tapping heads as pre-set assemblies, with repeatable location on every change, instead of a collet swap at the machine.
See Mongtec PSC32 tooling for the article numbers that mount on this output, or the PSC / Capto size overview for how PSC32 sits against the other sizes.
Coromant Capto® is a registered trademark of AB Sandvik Coromant. Mongtec is an independent brand with no affiliation to, endorsement by or licence from Sandvik. The Capto designation is used here only to identify the ISO 26623 polygon taper size; interchange in any specific application is confirmed by Mongtec engineering at RFQ.
Mongtec publishes tooling pages for machines with a declared BMT45 turret — see the BMT45 interface page. Confirming your model there does not confirm M0407 as the article number; that still comes from engineering.

M0407 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.
M0407 is rated to 6,000 rpm with 25 Nm of output torque at a 1:1 drive ratio. The usable figure is whichever is lower: this rating or your machine's live-tool drive rating.
They are the same nominal polygon taper size under ISO 26623. PSC32 is the standard designation; C3 is the Coromant Capto name for that size, and PSK C3 is the German-language form. Mongtec supplies PSC32; interchange with another maker's tooling in a specific application is confirmed by Mongtec engineering at RFQ.
M0407 is supplied with EC — external coolant. Coolant routing on the turret side differs between machine builders, so confirm the machine's coolant arrangement in the enquiry.
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 M0407 are supplied by email once the enquiry is open.
