Turrets & Live Tooling

Solid Engineering, Reliable Operation

Designed and Refined by Haas for More Than 20 Years

Customize your Haas lathe with a variety of turrets, or add live tooling to substantially increase your productivity.

Heavy-Duty Integral Coupler

Haas turrets now use an integral coupler that is 46% larger in diameter than on previous models. We machine the teeth of the coupler directly into the turret and turret housing to create a system that is more compact and robust than ever. The turrets use a dual-clamping system that provides 20% more clamping force than previous models, and a servo-driven spur-gear drive system that reduces indexing time by 25%.

Centerline Machining Method

We finish-machine our turrets as a complete unit – already assembled with the coupling, gearbox, and drive system. Keying off the turret’s centerline, we machine all critical features of each station using single-axis moves, and then index the turret to machine the next station. This ensures the absolute concentricity of each station with the turret’s true center. Compared to machining the turret before assembly, this reduces positioning variation from tool to tool by more than 90%. This results in easier job set up, higher accuracy, and better repeatability.    

BMT65 Turret with Live Tooling

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.

Turret Choices


The Haas 12-station bolt-on tool turret provides super-rigid mounting of turning tools and boring bars. The turret accepts industry-standard bolt-on toolholders around the perimeter, and has radial slots on the face for mounting turning tools in either the right- or left-hand direction.    


The Haas 12-station VDI turret accepts industry-standard live-tooling heads (when combined with the live tooling option) and stationary toolholders with VDI40 connections. A single locking wedge secures the toolholders in the turret, allowing quick, easy setups.    


The Haas 12-station hybrid turret accepts VDI40 tools (including live tools), as well as industry-standard bolt-on tools. The turret has 6 VDI stations and 6 bolt-on stations (radial slots for turning tools and perimeter stations for ID tools).

The Haas 12-station BMT65 turret provides extra-rigid mounting for turning and boring tools to improve cutting performance, and offers additional tool clearance when working with a tailstock. Industry-standard toolholders install easily, without additional alignment, to reduce setup times. The turret is available in both static and driven-tool versions.

The BMT65 turret with live tooling allows secondary operations – milling, drilling, slotting, and tapping – on the face of the part and around the diameter. To boost productivity even more, a half-index option is available for both versions that doubles your available tool stations to 24.

24-Station BMT65 Turret

Double Your Tool Capacity to 24 Tools

The BMT65 turret offers a half-station indexing option that increases your available tool stations to 24, with 12 of those stations able to accept driven tools. The turret looks the same on the outside, but will index every 15 degrees, rather than every 30 degrees. Special static toolholders are included with this option.

Set up Live tools properly
Properly setting up live tools on a turning center can be tricky. Mark guides you through the process with a step-by-step tutorial that will answer all your questions. If you have a Haas lathe with live tooling, or are considering getting one, this video is a must for you!
ST-10Y with live tooling
The ability to turn and mill complex parts and perform multiple operations on one machine increases throughput, reduces handling, and improves accuracy. The Haas ST-10Y is a small-footprint Y-axis turning center that provides 4" of Y-axis travel (±2" from the centerline) for off-center milling, drilling, and tapping, and comes standard with high-torque live tooling and a servo-driven C axis for versatile 4-axis capability.
ST-55 with extra-thick BOT turret
In this demo, we start with a workpiece weighing in at 2000 pounds! Starting with roughing cuts at 0.25" DOC and 0.025" per rev, we’re removing lots of material quickly. Even while profiling the curved surfaces, the button tool is taking a good-sized cut, with a 0.112" stepover and 0.050" per rev following a dynamic toolpath. By the time we’re done, we’ve removed more than 800 pounds of steel!
