The BMT65 Turret and Live Tooling for Haas Lathes

Why move your turned parts to a mill for secondary operations when you can machine them complete on a Haas lathe with the BMT65 Turret and Live Tooling?

Not only will your shop be more productive and experience reduced setup times, but the BMT65 Turret and Live Tooling also provide increased cutting performance, longer tool life, and better tool clearance, when compared to older Haas lathe models.

The BMT65 Turret and Live Tooling are standard on Haas Y-Axis lathes (ST-20Y through ST-35Y), and optional on non Y-axis models.
