Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, designs and engineers driven tool holders and static tooling for the EMCO ET 342 TCM on the open machine-side BMT and VDI (DIN 69880) standards. This model is published with a DIN1809 turret; Mongtec engineering confirms it against the actual turret drawing at RFQ, and every driven unit ships with an individual inspection report.
| Machine brand | EMCO |
|---|---|
| Model | ET 342 TCM |
| Turret interface | DIN1809 (published in a machine-specific tooling catalogue by a driven tool holder manufacturer; confirmed against the actual turret drawing at RFQ) |
| Driven tool holders | Axial, radial, adjustable-angle, twin-output, high-speed and geared-down units |
| Static tooling | Turning, boring bar, facing, cut-off and blank holders |
| Inspection | Individual inspection report with every driven unit |
| Origin | Taiwanese brand headquartered in Taichung, Taiwan |
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 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.
Machine builders routinely offer the same model with more than one turret — station count, model suffix and key count all change the mounting. Hardinge Conquest H51 is BMT55 in the 12-station build and BMT45 in the 16-station build; Okuma GENOS L300 M is VDI40 while L300 MW/MYW uses a 65×73 bolt pattern. It is the most common reason a driven tool holder arrives and will not bolt on. Reference table: 38 BMT turret bolt patterns by machine builder →

Machine-specific tooling catalogues publish this model with a DIN1809 turret. Machine builders do sometimes ship the same model with more than one turret, so Mongtec confirms the interface against the actual turret drawing before quoting. That check is free and takes one email.
The catalogue dimensioned drawing is published on the page of each Mongtec article number. After your enquiry Mongtec confirms compatibility with your actual spindle, turret or pull stud and gives the final article number — that check is free.
Yes. Special angles, extended reach, high-pressure internal coolant and non-standard mountings are supplied to order. Describe the operation and the machine.

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.
