Hobbing holders cut gear teeth and splines on the lathe by synchronising the hob with the main spindle, so a geared part is finished complete in one setup. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, builds them to mount on Haas turrets, published for BMT45, BMT65, BMT75, VDI40.
Designed for integrated gear machining. Gear hobbing traditionally relies on specialized equipment, increasing capital investment and process transfer costs. Montech hobbing units can be directly integrated into Haas multitasking centers, equipping them with continuous hobbing capabilities and enabling complete gear production on a single machine.
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.

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.
