Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies BMT and VDI (DIN 69880) driven and static tool holders. Tsugami builds Swiss-type sliding-head automatic lathes (B, BS, SS, BE series) and precision turret turning centers (M, TMA series); Mongtec's BMT/VDI holders apply to the turret machines. Pick your machine below, or contact engineering — the exact interface for a given model is confirmed at RFQ.
| Series | Type | Mongtec supply |
|---|---|---|
| M / TMA turret series | Turret turning center | BMT / VDI holders — size at RFQ |
| B / BS / BE / SS | Swiss-type sliding-head | Gang / Swiss interface — confirmed at RFQ |
Interface data is drawn from publicly available Tsugami machine specifications and tooling application listings. Mongtec's BMT and VDI holders apply to Tsugami turret turning centers; the Swiss-type sliding-head machines use a machine-specific gang interface confirmed 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®.

Mongtec supplies driven and static tooling across the Tsugami range. For the M / TMA / S turret machines these are BMT and VDI holders; for the Swiss-type sliding-head machines the tooling is gang/sliding-head and machine-specific, with the exact tool-station interface confirmed at RFQ. Model data is drawn from publicly available Tsugami specifications.
SS (Swiss sliding-head): SS20; SS26; SS207 / SS207-5AX; SS327-III / SS327-III-5AX (B-axis).
BS / BO / BU / BW / B (Swiss sliding-head): BS20C III; BS26C III; B0205-III; B0206; BO326-III; BO385L; BO386-III; BU20; BU26SY; BU38SY; BW209Z; SwissNANO.
M / TMA / S (turret & fixed-head, BMT/VDI): M08J-II; TMA8; S25D.
Holders published in the Mongtec Swiss Type Toolholders, Ver 2026.07 catalogue for Tsugami sliding-headstock (Swiss-type) lathes. Mongtec lists these against the Tsugami machine-builder reference code, because a Swiss-type holder position is machine-specific and has no BMT or VDI size to quote.

Tsugami builds Swiss-type sliding-head lathes (B, BS, SS Swiss and M / TMA turret). Their driven tools mount on a gang / Swiss interface rather than a BMT or VDI turret, so tooling is machine-specific — send the model and we confirm what can be supplied at RFQ. For any turret-type turning centers in the range, Mongtec supplies BMT and VDI holders.
A turret lathe indexes tools on a BMT or VDI turret disc; a Swiss-type (sliding-head) machine holds tools on a fixed gang with sliding-headstock motion. Mongtec supplies BMT and VDI turret holders; Swiss gang tooling uses a different, machine-specific interface confirmed at RFQ.
Send the model name and configuration via the contact page and engineering will confirm what Mongtec can supply for that interface.
It means the exact interface is verified against your specific machine before quotation.
Driven holders are built to 0.003 mm runout or better and ship with an individual inspection report.
