The Mazak Integrex i-250 / 350 / 450H ST uses a BMT 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.

Mazak turret rule: 2-axis turning models (no live tooling) use a BOT bolt-on turret and take Mongtec bolt-on static holders. Live-tool models (M / MY / MS / MSY) use the BMT68 driven-tool turret; larger QT 300/350 12-station builds use BMT80. Mazak's VDI40 turret is a Mazak-specific clamping system — a standard VDI40 holder does not fit, but Mongtec supplies VDI40 holders to the Mazak interface.

Mongtec also supplies BMT40, BMT60, BMT68 and BMT80 holders and builder-specific interfaces (Mazak, Nakamura-Tome, Haas BOT, Okuma BOT, Muratec BOT) — the 228 article numbers published here are a subset of the range. Mongtec tooling is exported to five continents and supplied to machine-tool builders. Lead time is confirmed per item and quantity at quotation.

Mongtec supplies BMT and VDI (DIN 69880) driven tool holders and static tooling compatible with the Mazak turret platform. Interface: BMT. 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 →

The turret interface for this machine is confirmed at RFQ, so no article number is published here. These are the driven tool types Mongtec publishes — which one fits is confirmed once the turret is identified.
