Speeder holders step the turret drive up so small-diameter cutters reach their correct surface speed on a lathe whose driven-tool spindle cannot turn fast enough. 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 high-speed machining requirements of Haas multitasking centers. Designed to break through the RPM limits of traditional turrets, these toolholders significantly boost output RPM via an internal high-precision speed-increasing mechanism. They perfectly address insufficient cutting speeds in small-diameter drilling, micro-machining, and high-speed precision milling—helping customers achieve high-efficiency and high-precision process integration on their Haas machines.
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.
