Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies BMT and VDI (DIN 69880) driven tool
holders, static holders and quick-change tooling for Hyundai WIA CNC lathes and turning centers. Select your machine below,
or contact engineering if your model is not listed
— interface dimensions are confirmed per machine at RFQ.
The Mongtec Static Turret Toolholders, Ver 2026.07 catalogue names this machine platform for turret sizes BMT55, BMT65, BMT75. 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.

FAQ
Which turret interface do Hyundai WIA lathes use?
It depends on the machine, not on the brand. Across the 48 Hyundai WIA models documented on this site the published interfaces are: BMT65 on 5 models (such as HD2600 / 3100M, L2100SY, LM2000 / 2500 TTM/TTMS/TTSY); BMT55 on 3 models (only L230LMSA, LM1600 / 1800 TTSY, SKT160 / 180 TTMS/TTSY); BMT45 on 1 model (only SE2200 LSY). A further 39 models are not yet published with an interface and are confirmed per configuration at RFQ. Some models appear under more than one interface because the same designation ships with different turret options. Send the model designation and turret station count and Mongtec engineering confirms it against the actual turret drawing.
Which BMT size does my Hyundai WIA lathe use?
It varies by model and turret station count. Send the full model designation and the number of turret stations; Mongtec engineering matches it against the turret drawing before quoting. Many models on this page are not yet published with a turret interface and are confirmed per configuration at RFQ.
Will a Mongtec driven tool holder fit my Hyundai WIA turret?
Mongtec supplies on the same open machine-side standards Hyundai WIA turrets use — BMT face-and-taper, VDI polygonal shank to DIN 69880, and PSC polygon coupling to ISO 26623. Because BMT is an industry de-facto standard rather than an ISO or DIN standard, fitment is confirmed per machine: send the model designation and turret station count (a photo of the turret face or the machine spec sheet helps) and Mongtec engineering confirms it against the actual turret drawing before quoting.
My Hyundai WIA model is not in the list above — can you still supply?
In most cases yes. The list covers models already documented by Mongtec; it is not the limit of what Mongtec can supply. Custom and special-configuration units are a standard part of the work, and Mongtec supplies turret interfaces beyond the article numbers published on this site. Send the model designation and turret station count and engineering will confirm.
Do you supply static holders and boring bar holders as well as driven tools?
Yes. Static turning, boring bar, facing, cut-off and blank holders are supplied on the same turret interfaces as the driven units, alongside quick-change tooling and angle heads.
What quality documentation ships with the tooling?
Every driven unit ships with an individual inspection report for that specific unit — measured values, not a generic batch certificate.
What is the lead time?
Mongtec does not publish a blanket lead time. It is confirmed according to the items and quantities the customer requests, once interface, quantity and any customisation are reviewed. Request a quote for a project-specific answer.
Does Mongtec repair driven tools from other brands used on Hyundai WIA machines?
Mongtec's Taiwan service centre works on driven tool holders and angle heads. Whether a specific third-party brand and model is covered is confirmed case by case on request.
