Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies BMT and VDI (DIN 69880) driven and static tool holders for Biglia (Italy) turning centers — the B-series, BV and Quattro turning centers. Each driven holder is built to ≤0.003 mm runout. Pick your machine below, or contact engineering — the exact interface for a given model is confirmed at RFQ.
Mongtec’s selection guide lists Biglia machines under the turret interfaces below. Where a model on this site appears in the guide, that interface is the one Mongtec quotes against; models not named in the guide are confirmed from a photo of the turret face. The same data drives the AI assistant on this site.
| Turret interface | Biglia models named in the guide | Article numbers in that section |
|---|---|---|
| BMT40 (50×50 mm) | EUROTECH B436 / B438 | 8 static · 2 driven |
| BMT55 inch (65×63 mm) | EUROTECH B446 T2 / B465 T2 / B620 / E42SL / EUROTECH B446 T3 / B465 T3 / B545 / B565 / B745 / B765 | 15 static · 2 driven |

| Series | Type | Mongtec supply |
|---|---|---|
| BMT / VDI | B301-B1200, B436/B438, B446-B765 | Driven & static holders — size at RFQ |
| 16-station disc turret | B750 / B1250 | Driven & static holders — confirmed at RFQ |
| Twin-turret | Quattro B445 / B470 | Driven & static holders — confirmed at RFQ |
Interface data is drawn from publicly available machine-builder specifications and tooling application listings. Where a model's interface is not published, Mongtec confirms the BMT bolt pattern or VDI type and drive at RFQ — "confirmed at RFQ" verifies the interface, it does not mean the model is outside our supply range. Mongtec supplies open-standard BMT and VDI interfaces; it does not supply or claim compatibility with proprietary quick-change systems such as WTO QuickFlex®.
Also covered (send configuration for RFQ): other Biglia B, BV and Smart-series turning centers.
Beyond the machines linked above, Mongtec supplies BMT and VDI driven and static tool holders for these Biglia configurations, with the interface confirmed at RFQ: B42 (VDI30), B446 T2 / B465 T2, B446 T3 / B465 T3, B545 / B565, B620, B745 / B765, B750 / B1250 (12-station turret), BMX 45 Y2, BMX 51 / 70 / 80 Y2, and the BV210 / BV315 vertical turning centers. Send your model and turret and Mongtec engineering confirms the exact BMT size or VDI type before quotation.
Biglia turning centers use BMT disc turrets and VDI turrets depending on model, including 16-station and twin-turret builds. The exact size and coupling depend on the model and build; send your machine details and Mongtec confirms the interface at RFQ.
Yes. Mongtec designs and engineers driven (live) and static holders for Biglia BMT and VDI interfaces, including axial, radial, adjustable-angle and multi-output configurations, matched to the machine's drive coupling.
Very likely yes. Send the model name and turret type via the contact page and engineering will confirm availability and interface.
It means the exact interface dimensions (BMT size or VDI type, drive coupling) are verified against your specific machine before quotation. It does not mean the model is outside Mongtec's supply range.
Driven holders are built to 0.003 mm runout or better. Materials, heat treatment and gear specifications are documented for each order.
Figures below are Mongtec's own published line specifications (mongtec-tools.com, accessed 2026-07-20). They describe the capability range of the product line; the rating of a specific unit for a specific machine is confirmed by Mongtec engineering at RFQ.

| Driven tool 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 the Mazak-compatible 0° driven tool line; other families confirmed at RFQ |
| Bearings / gearing | Imported P4/P5 precision bearings; precision-ground spiral bevel gear pairs |
| Product types | Driven holders (axial / radial / adjustable-angle), static holders, boring bar holders, custom configurations |
| Lead time | No blanket published figure — quoted per order after interface, quantity and customisation are reviewed |
