Haas Double 90° Single-Side Twin-Spindle Driven Tools

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 Haas turrets, published for BMT45, BMT65, BMT75, VDI40.

Developed specifically for the lateral machining requirements of Haas multitasking centers. Combining 90° lateral transmission with a double-output spindle design to maximize space utilization and machining efficiency. This toolholder provides dual-direction tool output in a single station, reducing tool-change frequency and optimizing cycle times—helping customers achieve high-efficiency process integration on their machines.

Getting the right holder

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.
