Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies BMT and VDI (DIN 69880) turret tool holders. Star Micronics builds Swiss-type sliding-head automatic lathes (SR, SV, SX families) whose driven tools mount on a gang / Swiss interface confirmed per machine at RFQ. Pick your machine below, or contact engineering — the exact interface for a given model is confirmed at RFQ.
| Series | Type | Mongtec supply |
|---|---|---|
| SR-20 / SR-32 | Swiss-type sliding-head | Gang / Swiss interface — confirmed at RFQ |
| SV-20R | Swiss-type sliding-head | Gang / Swiss interface — confirmed at RFQ |
| SX-38 | Swiss-type sliding-head | Gang / Swiss interface — confirmed at RFQ |
Interface data is drawn from publicly available machine specifications and tooling application listings. These are Swiss-type sliding-head machines whose driven tools mount on a gang / Swiss interface rather than a BMT/VDI turret; that interface is machine-specific and is confirmed per machine at RFQ. Mongtec's open-standard BMT and VDI holders apply to turret-type turning centers. 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 Star SR, SV, SW and SX-series sliding-head lathes.
Mongtec supplies driven and static tooling for Star sliding-headstock (Swiss-type) turning centers. Swiss tooling is gang/sliding-head and machine-specific; the exact tool-station interface is confirmed at RFQ.

Holders published in the Mongtec Swiss Type Toolholders, Ver 2026.07 catalogue for Star sliding-headstock (Swiss-type) lathes. Mongtec lists these against the Star machine-builder reference code, because a Swiss-type holder position is machine-specific and has no BMT or VDI size to quote.

Star Micronics builds Swiss-type sliding-head lathes (SR, SV, SX). 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.
