Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders and static tooling for the Okuma LT 3000 EX M/MY 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 | Okuma |
|---|---|
| Model | LT 3000 EX M/MY |
| Turret interface | BMT bolt pattern 65×73 (cross-referenced from published tooling catalogues; the actual turret drawing is confirmed 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) |
| Quality assurance | Each driven unit ships with an individual inspection report |
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 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. Every Mongtec driven tool holder is inspected before shipment (runout, torque, balancing) and ships with an individual inspection report.
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 →

Yes — Mongtec supplies driven and static tool holders for this turret. This Okuma turret uses a 65 × 73 mm BMT bolt pattern, which is Okuma-specific and not the same as the generic BMT65 sizes published as article numbers on this site. Mongtec supplies to the Okuma pattern regularly.
Turret coverage: Okuma GENOS L300 MW, MYW (radial) · LB2000, 2500, 3000 EX-M, EX-MW · MULTUS U3000, U4000 · GENOS L3000-EM · LU3000 EXM / MY.
Mongtec driven and static tool holders are exported worldwide across five continents, and are supplied to machine tool manufacturers as well as to end users. Lead time is confirmed against the items and quantity you need.
To quote we need: the machine model and turret designation, the station count, a turret interface drawing or a clear photo of the turret face, the holder orientation (axial or radial) and the clamping or collet size you need, and the quantity. A drawing of the holder you are replacing works just as well.

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 →

This machine is documented by its turret bolt pattern (65×73 mm), not by a nominal BMT size — the bolt pattern is what decides whether a holder mounts. Mongtec publishes the driven tool types below and builds to machine-specific patterns; the article number is confirmed against the actual turret drawing at RFQ.
