Double 90° holders carry two right-angle outputs from one turret station, so two cross features are cut without indexing the turret between them. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, builds them to mount on Hardinge turrets, published for BMT45, BMT55.
Engineered specifically for Hardinge multitasking turning-milling centers, our Double 90° Degree Driven Tools combine side-machining capability with a dual-tool position design to achieve high-efficiency, multi-process integration.
Through its dual-tool configuration and precision 90° transmission structure, multiple lateral milling and drilling operations can be completed with a single toolholder. This significantly reduces tool-change intervals and secondary setup requirements, boosting overall cycle times and capacity utilization.
10 Hardinge 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.
