Double 90° single-side twin-spindle holders place two radial spindles on the same side of one station — two cross holes at a fixed pitch in one plunge. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, builds them to mount on Index turrets, published for VDI25, VDI30, VDI40.
Engineered specifically for the advanced machining requirements of Index multitasking turning-milling centers, this toolholder combines a 90° lateral machining structure with a twin-spindle design and Y-axis offset capability to achieve highly integrated multitasking applications.
Through its multi-axis integrated design, it enables lateral milling, multi-hole pattern machining, and offset machining in a single setup. This effectively reduces tool-change frequency and secondary positioning errors, enhancing overall machining precision and production line efficiency.
19 Index 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.

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.
