Overview
The Haas ST-10LY combines the long-bed Z-axis of the ST-10L with Y-axis and live tooling capability, creating the most compact long-bed mill-turn machine in the Haas lineup. With 610 mm (24 in) of Z-travel, +/-50.8 mm (+/-2.0 in) of Y-axis travel, and a BMT45 turret with 4,000 RPM live tooling, the ST-10LY handles done-in-one work on longer parts that need both turning and milling.
The A2-5 spindle delivers 14.9 kW (20 hp) and 102 Nm (75 ft-lb) of torque at 1,300 RPM, with a max speed of 6,000 RPM. The 44.5 mm (1.75 in) bar capacity and 165 mm (6.5 in) chuck keep the machine in the compact class, but the Y-axis and live tooling transform it from a simple turning center into a genuine multi-tasking cell.
Max cutting diameter is approximately 279 mm (11 in) with the BMT45 turret. Axis travels are 200 mm (7.9 in) in X, +/-50.8 mm in Y, and 610 mm (24 in) in Z. Rapids run at 12 m/min (472 ipm) on X and Y, and 30.5 m/min (1,200 ipm) on Z. The C-axis holds +/-0.01 degrees for precision milling work.
The ST-10LY fills a niche for shops machining small-diameter complex parts on longer stock — medical components, firearms parts, precision fittings, and instrumentation housings that need cross-drilling, flat milling, and tapping along with OD and ID turning.
At roughly $80,000-$110,000 configured, the ST-10LY delivers long-bed Y-axis mill-turn capability at the entry level of the Haas lineup. It eliminates second-op VMC work on longer parts while keeping the footprint and investment compact.

Strengths & Limitations
Strengths
- Long-bed Y-axis mill-turn capability in the most compact package Haas offers — ideal for tight floor plans
- 6,000 RPM spindle speed delivers excellent surface speeds on small-diameter aluminum and brass finishing
- BMT45 turret with 4,000 RPM live tooling enables cross-drilling, flat milling, and tapping on longer parts
- 610 mm (24 in) Z-axis travel handles longer complex parts that won't fit the standard ST-10Y bed
- C-axis at +/-0.01 degrees provides precision for interpolated milling and positioning work
- At $80-110K configured, the most affordable long-bed Y-axis lathe from a tier-one manufacturer
Limitations
- 1.75-inch bar capacity limits the machine to small-diameter bar work; larger stock requires the ST-15LY or ST-20LY
- 15 hp spindle limits heavy roughing in stainless and tougher alloys on longer parts
- BMT45 turret is smaller and less rigid than the BMT-65 used on the ST-20LY and larger machines
- 30-gallon coolant tank is small for sustained production with live tooling generating additional heat

Frequently Asked Questions
01
Base price starts around $80,000. Adding sub-spindle option, parts catcher, chip conveyor, and common options pushes the configured price to $95,000-$110,000. The long-bed plus Y-axis premium over the standard ST-10 is approximately $35,000-$40,000.
02
The ST-10LY adds approximately 200 mm (8 in) of Z-axis travel, going from 406 mm to 610 mm (24 in). The spindle, Y-axis, turret, and live tooling specs are identical. Choose the LY when your parts with off-center features regularly exceed the standard bed length.
03
Yes. The ST-10LY can be ordered with an optional sub-spindle for back-working operations, enabling complete done-in-one machining on longer parts. The sub-spindle combined with Y-axis and live tooling creates a comprehensive small-part manufacturing cell.
04
The ST-20LY has a larger 2.5-inch bar capacity, 20 hp spindle, A2-6 nose, 8.3-inch chuck, and BMT-65 turret with 6,000 RPM live tooling. The ST-10LY is more compact and affordable with 6,000 RPM spindle speed. Choose the ST-10LY for small-diameter work. Choose the ST-20LY for larger bar stock and more milling power.
