Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders and static tooling for the Hanwha STL42 H/N/NH on the open machine-side BMT and VDI (DIN 69880) standards. The turret interface for this model is confirmed per machine configuration by Mongtec engineering at RFQ.
| Machine brand | Hanwha |
|---|---|
| Model | STL42 H/N/NH |
| Turret interface | VDI30 (stated in the machine-specific tooling catalogue published by a driven tool holder manufacturer; confirmed against the actual turret drawing at RFQ) |
| 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 (0° axial driven line) |
Same model, different turret: station count, model suffix and build year change the turret interface. Mongtec confirms the interface from the machine model and a turret photo before quoting.

Mongtec supplies BMT and VDI (DIN 69880) driven tool holders and static tooling compatible with the Hanwha turret platform. Interface: VDI30. 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.
