The Victor VTurn-40 / 45 CM/YCM uses a BMT75 turret interface. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders and static tooling on the open machine-side BMT and VDI (DIN 69880) standards used by this machine class. The exact Mongtec model for your machine configuration is confirmed by Mongtec engineering at RFQ, and every driven unit ships with an individual inspection report.
| Machine brand | Victor |
|---|---|
| Model | VTurn-40 / 45 CM/YCM |
| Turret interface | BMT75 |
| Driven tool line speed | 6,000–12,000 rpm standard (up to 32,000 rpm with speed increaser) |
| Max torque | Up to 160 Nm (line capability; unit rating confirmed at RFQ) |

This machine uses a BMT75 turret interface. Mongtec publishes the following static (non-driven) turret holders for BMT75 — OD, double-OD, ID and face types:
Ordering codes are machine-builder specific. The designations below identify the holder type and its dimensions. Because mounting details differ between machine builders even within the same nominal turret size, the same BMT specification can carry a different Mongtec article code depending on the machine it is built for — Mongtec engineering assigns the correct code for your machine at RFQ.

Representative photographs of Mongtec driven and static turret tooling in the BMT75 class. These are production units from the Mongtec range, not renderings — but they are shown as examples of the BMT75 product family, not as the confirmed article number for this machine. Mongtec engineering verifies the interface, clearance and correct article code for your specific machine at RFQ.
Mongtec supplies BMT and VDI (DIN 69880) driven tool holders and static tooling compatible with the Victor turret platform. Interface: BMT75. The exact configuration is confirmed by Mongtec engineering at RFQ.
Yes. BMT and VDI are open machine-side standards, so switching supplier does not require any turret modification. Mongtec also publishes cross-reference pages for WTO, Heimatec, EWS, Eppinger, BIG and other brands.
Lead time is quoted per order and ships from Taichung, Taiwan. Every Mongtec driven tool holder is inspected before shipment (runout, torque, balancing) and ships with an individual inspection report.

Machine builders regularly ship the same model with different turrets — station count, model suffix and the number of keys all change the mounting. The Hardinge Conquest H51 is BMT55 in the 12-station build and BMT45 in the 16-station build; the Okuma GENOS L300 M is VDI40, while the L300 MW/MYW uses a 65×73 mm bolt pattern. This is the single most common reason a driven tool holder arrives and will not bolt on. BMT bolt pattern reference — 38 patterns by machine builder →

Whether a holder mounts is decided by the turret bolt pattern and the drive coupling, not by the machine name alone. The types below are published by Mongtec for this interface; the exact article number is confirmed against the actual turret drawing at RFQ.
