Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, manufactures BMT (Base Mounted Turret) and VDI driven and static tool holders for SMEC turning centers — the SL slant-bed and PL vertical families. SMEC Co., Ltd. is the successor to the Samsung Machine Tools business, so SL/PL machines branded Samsung or SMEC share the same tooling. 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 is confirmed at RFQ.
SMEC SL and PL turning centers use BMT (Base Mounted Turret) disc turrets, sized by machine class. Mongtec supplies driven and static holders for each size; VDI-configured machines are also covered. The exact size for your machine is confirmed before quotation.
| Series | Type | Turret / Mongtec supply |
|---|---|---|
| SL-3000 M/Y/SY | Slant-bed, Y-axis / sub-spindle | BMT disc turret — driven & static holders, size at RFQ |
| SL-6500 / 8500 M | Large slant-bed | Larger BMT disc turret — size at RFQ |
| PL-250 V / VM | Vertical turning center | BMT disc turret — driven & static holders, size at RFQ |
Interface data is drawn from publicly available SMEC / Samsung machine specifications and tooling application listings. Where a model’s BMT size is not published, Mongtec confirms the disc bolt pattern 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 manufacture or claim compatibility with proprietary quick-change systems such as WTO QuickFlex®.
Also covered (send configuration for RFQ): SL-1500 / 1800 / 2000 / 2500 M/Y/SY, PL-2000 / 2500, and other SL/PL slant-bed and vertical machines from the SMEC and Samsung Machine Tools range.
Mongtec supplies BMT and VDI driven and static tool holders across the SMEC (formerly Samsung) turning-center range; the interface is confirmed at RFQ.

The Mongtec Static Turret Toolholders, Ver 2026.07 catalogue names this machine platform for turret sizes BMT45, 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.

SMEC Co., Ltd. is the successor to the Samsung Machine Tools business. SL and PL turning centers branded Samsung or SMEC share the same turret interfaces, so Mongtec tooling for one applies to the other. Confirm the exact model at RFQ.
SMEC SL and PL turning centers use BMT (Base Mounted Turret) disc turrets sized by machine class. Send your model and turret and Mongtec confirms the exact BMT size at RFQ.
Yes. Mongtec designs and engineers driven (live) and static holders for SMEC BMT and VDI interfaces, including axial, radial, adjustable-angle and multi-output configurations, matched to the machine’s drive coupling.
Very likely yes. Mongtec supplies across the SL and PL range. Send the model name and turret type via the contact page and engineering will confirm availability and BMT size.
Driven holders are built to ≤0.003 mm runout and ship with an individual inspection report. Materials, heat treatment and gear specifications are documented for each order.
