Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders for CNC turning centers on the same open machine-side turret standards used by WTO Werkzeug-Einrichtungen GmbH’s Performance Series® program — BMT (per machine builder spec) and VDI per DIN 69880. Mongtec’s driven-tool line is published at 6,000–12,000 rpm standard (up to 32,000 rpm with a speed increaser), up to 160 Nm torque, and up to 100 bar internal/external coolant, across the same 1:1 / 1:2 / 2:1 gear-ratio configurations WTO offers. Unit-for-unit runout, torque, and lead time for a specific WTO model are confirmed only after Mongtec engineering completes a signed cross-reference — see the table below.

WTO ships from Ohlsbach, Germany, with regional sales and service centers in the USA and Asia (WTO GmbH, wto-tools.com, accessed 2026-07-09). Mongtec ships from Taiwan and quotes lead time per order after reviewing the specific interface, quantity, and any customization — there is no single published lead-time figure to compare against WTO's at this time. Request a cross-reference quote below for a project-specific lead time.
Mongtec is Taiwan-based and already services driven tool holders and angle heads for a number of international brands, including WTO units, through its Taiwan Service Center (Mongtec General Catalog Ver 2026.06, p.43, mongtec-tools.com, accessed 2026-07-09). This means Mongtec-supplied BMT/VDI driven tooling and post-sale support both run through the same regional point of contact.
Both WTO and Mongtec driven tool holders mount on open machine-side standards (BMT, VDI/DIN 69880), so switching does not require a turret change. Mongtec's published driven-tool-line capability (up to 160 Nm torque, up to 32,000 rpm with a speed increaser, up to 100 bar coolant — Mongtec General Catalog Ver 2026.06) is comparable in class to WTO's Performance Series® program, though a like-for-like cost comparison depends on the specific unit and has not been performed for this page.
Mongtec driven tool holders go through a documented production and inspection flow: material preparation, body finishing, spindle finishing, assembly, input-end inspection, output-end inspection, and packaging/shipment (Mongtec General Catalog Ver 2026.06, p.9, mongtec-tools.com, accessed 2026-07-09). Interface dimensions for a specific cross-reference (e.g. matching a WTO unit's turret mount and gear ratio) are confirmed by Mongtec engineering against the customer's machine and current WTO catalog data before any compatibility level is assigned on this page.
Mongtec supplies BMT and VDI driven tooling for the same machine brands WTO serves, including Mazak, DMG MORI, Okuma, DN Solutions/Doosan, and Nakamura Tome (mongtec-tools.com/en-US/plist1-bmt-vdi-tool-holder, accessed 2026-07-09). Model-family pages below link to Mongtec's live catalog by machine brand; individual model-to-model cross-references are confirmed by Mongtec engineering at RFQ.
If a WTO unit on your machine is worn, damaged or discontinued, you do not need the original article number to replace it. Send the model number, the name plate photo, or the drawing of the driven tool holder you run today — Mongtec engineering cross-references the mounting, coupling and output geometry and quotes a suitable Mongtec article, stating clearly which dimensions were confirmed. Repair of the existing unit is sometimes the better answer; where we see that, we say so.
Mongtec publishes this comparison so buyers can judge the swap themselves. It is not a claim that one brand is better than the other — the two are different companies with different ranges, and the right choice depends on the machine and the job.
Send it to info@mongtec.com or use the enquiry form. A drawing or a photo of the unit on the turret speeds this up; neither is required to start.
