OD static holders clamp turning tools for outside-diameter work — the non-driven stations of the turret, matched to the same bolt pattern as the driven holders. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies them to mount on Haas turrets, published for BMT45, BMT65, BMT75, VDI40.
Designed specifically for Haas high-performance multitasking centers. The housing is manufactured from high-quality alloy steel with integrated heat treatment, providing ultimate clamping rigidity. Tailored to the precision positioning requirements of Haas turrets (such as the ST series), these toolholders ensure long-term stability and vibration damping during both rough and finish O.D. turning operations, helping customers achieve rapid production and high repeatability.
16 Haas models. Where the turret interface is published it is shown; where it is blank the interface depends on the turret actually fitted and is confirmed at enquiry.

All machine builders for od static toolholders →
The machine model alone does not decide the holder. The same model can leave the factory with different turrets — station count, model suffix and key arrangement all change the mounting. Tell us the machine, the turret and the operation and we confirm the mounting before quoting.
Already using another brand? Send the drawing or the article number of the holder you run today and Mongtec will convert it to an equivalent Mongtec holder — same mounting, same reach, same output.
Mongtec publishes static OD turning holders for 13 Haas machine models, on turret interfaces BMT45, BMT65, BMT75, VDI40. On these machines the holder is used for holding square-shank turning, facing, grooving and parting tools for outside-diameter work. Article numbers are matched to the machine at RFQ — we confirm the turret interface from the builder’s drawing rather than assume it from the model name.
