Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders and static tooling for the Okuma GENOS L300 MW/MYW on the open machine-side BMT and VDI (DIN 69880) standards. This model is listed under BMT 65×73 mm in Mongtec’s TOOL HOLDER SELECTION GUIDE; published machine data also reports VDI40, 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.

| Model | GENOS L300 MW/MYW |
| Turret interface | Mongtec's TOOL HOLDER SELECTION GUIDE lists the Okuma GENOS L300 MW/MYW under BMT 65×73 mm. Published machine data also reports VDI40; 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 (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.

Article numbers shown as links have a specification page with the catalogue drawing. The rest are published in the Mongtec selection guide; Mongtec confirms the final article number against your turret drawing at RFQ.
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.

Builds sold under the Okuma GENOS L300 MW/MYW name do not all carry the same turret, and the turret decides which Mongtec tool holder fits. This page covers the MW (live tooling, second spindle), MYW (live tooling, Y-axis, second spindle) builds.
Check the turret face against the interfaces shown on this page:
| Interface | What to check on the turret |
|---|---|
| BMT 65×73 mm bolt pattern | Bolt spacing 65×73 mm — a pattern used by Okuma. |
| VDI40 | Tool-shank bore ø40 mm (DIN 69880 / ISO 10889). |
Count the turret stations, photograph the turret face and the machine serial plate, and email them with the model name. The interface for your machine is confirmed in Mongtec's formal quotation.
Mongtec supplies BMT and VDI (DIN 69880) driven tool holders and static tooling compatible with the Okuma turret platform. Interface: BMT bolt pattern 65x73. 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.
BMT is an industry de-facto standard, not an ISO or DIN standard, so this turret is identified by its bolt-hole pattern rather than a plain BMT size number. The pattern is what actually determines whether a holder bolts on. How BMT bolt patterns differ by machine builder →
Okuma publishes more than one turret build under the GENOS L300 name, and they do not take the same holder:
| Model | Turret mounting |
|---|---|
| GENOS L300 M | VDI40 |
| GENOS L300 MW / MYW (this page) | BMT bolt pattern 65×73 — shared with LB3000 EX and LU3000 EX |
| GENOS L3000e M / MY | Published in both groups — the build must be confirmed |
This is normal, not an anomaly: the same machine model is frequently offered with more than one turret, and the turret — not the model name — decides which holder fits. It is the single most common reason a driven tool holder arrives and will not bolt on. Send the turret drawing or the machine serial number and we confirm the fit before quoting →

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.
