Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders and static tooling for the Mazak QT-Ez 8 / 10 / 12 M/MY/MSY on the open machine-side BMT and VDI (DIN 69880) standards. This model is listed under BMT68 in Mongtec’s TOOL HOLDER SELECTION GUIDE; published machine data also reports BMT55, so the fitted turret depends on the build, published by Mongtec for this machine. The exact Mongtec model for your machine configuration is confirmed by Mongtec engineering at RFQ.

| Turret interface | Mongtec's TOOL HOLDER SELECTION GUIDE lists the Mazak QT-Ez 8 / 10 / 12 M/MY/MSY under BMT68. Published machine data also reports BMT55; the fitted turret depends on the build. Send a photo of the turret face and Mongtec confirms the fit before quoting. |
| 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) |
| Coolant | Internal / external, up to 100 bar |
| Runout | ≤0.003 mm published for Mazak-compatible 0° driven tool line; other families confirmed at RFQ |
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. The same model can be built with a different turret, so this is a general rule, not a confirmed interface for your machine — email the machine model and a photo of the turret face; the interface is confirmed in Mongtec's formal quotation.

Mongtec supplies BMT and VDI (DIN 69880) driven tool holders and static tooling compatible with the Mazak turret platform. Interface: Mazak-specific BMT bolt pattern 68x110 (D68). 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.

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.
