Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies BMT and VDI (DIN 69880) driven and static tool holders for INDEX (Traub) turning centers — the B-series turret machines and G-series. Each driven holder is built to ≤0.003 mm runout with a supplied inspection report. Pick your machine below, or contact engineering — the exact interface for a given model is confirmed at RFQ.
| Series | Type | Mongtec supply |
|---|---|---|
| B400 / B500 | Turret-type turning centers | BMT / VDI holders — size at RFQ |
| G420 | Turn-mill / multi-function | Interface confirmed at RFQ |
Interface data is drawn from publicly available INDEX machine specifications and tooling application listings. INDEX machines may use BMT, VDI or an INDEX W-serration quick-change turret; the exact interface is confirmed per machine at RFQ. 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 INDEX B and C turning centers. INDEX multi-spindle (MS) machines use machine-specific interfaces confirmed at RFQ.
Mongtec supplies VDI driven and static tool holders across the INDEX turning-center range; the published VDI size is noted for each family and the exact type is confirmed at RFQ.
ABC / B-series: ABC (SpeedLine); B400 (VDI30); B400 / B500 (VDI40, radial tooling turret); B400 / B500 (VDI40, face tooling turret).
C-series: C65 / C100 / C200 (VDI25); C200 (VDI30).
G-series: G160 / G200 / G220 (VDI25); G200.3 / G220 / G250 / G300 / G300.2 / G320 (VDI30); G250 (VDI40); G300 (VDI40); G300.2 / G320 / G400.2 / G420 / G500 / G520 (VDI40); G400 (VDI40).
MS multi-spindle: MS22; MS22-8; MS22 / MS32 / MS40 (VDI25); MS52 (VDI30).
V vertical: V160 / V200 (VDI25); V160 / V250 / V300 (VDI30); V250 / V300 (VDI40).
INDEX B400 and B500 turning centers may be configured with BMT, VDI or an INDEX W-serration quick-change turret. Send your machine details and Mongtec confirms the exact interface at RFQ.
Yes, for the open-standard BMT and VDI interfaces. For the INDEX W-serration quick-change interface, send the machine details for confirmation at RFQ.
INDEX and Traub are part of the same group. Mongtec covers both; see the dedicated Traub page for the TNA series.
It means the exact interface dimensions 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 and ship with an individual inspection report.
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.
