Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders and static tooling for the Mazak Quick Turn Smart 300 / 350 M 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, and every driven unit ships with an individual inspection report.
| Machine brand | Mazak |
|---|---|
| Model | Quick Turn Smart 300 / 350 M |
| Turret interface | BMT68 — listed for this model in Mongtec TOOL HOLDER SELECTION GUIDE Ver 2026.08; confirmed against the actual turret drawing at quotation |
| 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 |
| Quality assurance | Each 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: BMT68. 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.

We have not published an interface for this model because the public machine specifications do not state it consistently, and a guessed figure is worse than a blank field. Three steps settle it:
BMT is not published by ISO or DIN, so even the marking in step 2 is a starting point, not proof. The drawing decides.
Machine builders routinely ship the same model with more than one turret. These are all published, verified examples:
| Machine | What changes | Turret mounting |
|---|---|---|
| Hardinge Conquest H51 | station count | 12-station = BMT55 · 16-station = BMT45 |
| Okuma GENOS L300 | model suffix | L300 M = VDI40 · L300 MW/MYW = 65×73 bolt pattern |
| DMG MORI ALC / ALX 1500–2500 | turret build | BMT40 or BMT42/64 |
| DMG MORI NZX 2500 | turret build | BMT40 or BMT60 |
| Takisawa TS-3000 / 4000 | key count | 2-key and 3-key turrets are not interchangeable |
This is why a published spec sheet cannot answer the question for every machine, and why Mongtec verifies the turret drawing before quoting rather than selling against a nominal size. It is also 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 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.
