Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies BMT and VDI (DIN 69880) driven and static tool holders for Jyoti (India) turning centers — the AX and TMC series. 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.
| Series | Type | Mongtec supply |
|---|---|---|
| BMT disc turret | Most turning-center models | Driven & static BMT holders — size at RFQ |
| VDI (DIN 69880) | Models with a VDI turret | Driven & static VDI holders — confirmed at RFQ |
Interface data is drawn from publicly available machine-builder specifications and tooling application listings. Where a model's BMT size or VDI type is not published, Mongtec confirms the disc bolt pattern or coupling 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 Jyoti AX, DX and TMC turning centers.
The Mongtec Static Turret Toolholders, Ver 2026.07 catalogue names this machine platform for turret sizes BMT45, BMT55, BMT65. Published static (non-driven) holders — OD, double-OD, ID and face types:
Ordering codes are machine-builder specific. The designations below identify the holder type and its dimensions. Because mounting details differ between machine builders even within the same nominal turret size, the same BMT specification can carry a different Mongtec article code depending on the machine it is built for — Mongtec engineering assigns the correct code for your machine at RFQ.

Dimensions in mm, from the Mongtec Static Turret Toolholders, Ver 2026.07 catalogue. This is the published range for those turret sizes, not a confirmed fit for a specific machine configuration — Mongtec engineering verifies interface dimensions, clearance, shank size and the correct article code per machine at RFQ. Ask engineering to confirm →
Jyoti turning centers use BMT disc turrets (and VDI on some models) sized by machine class. Send your model and turret and Mongtec confirms the exact interface at RFQ.
Yes. Mongtec designs and engineers driven (live) and static holders for Jyoti 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.
