Torque and bar size. The ST-25L has 30 hp (22.4 kW), 300 ft-lbf (407 N·m) at 500 rpm, a 10 in (254 mm) chuck and 3 in (76 mm) of bar capacity. The ST-20L has 20 hp (14.9 kW), 150 ft-lbf (203 N·m), an 8.3 in (210 mm) chuck and 2.5 in (64 mm) of bar capacity, but a higher top speed of 4,000 rpm. Both have 42.5 in (1,080 mm) of Z.
13 in (330 mm) in diameter and 42.5 in (1,080 mm) long, under a swing of 21 in (533 mm). Through the spindle, bar up to 3 in (76 mm) passes a 3.5 in (88.9 mm) bore. With a BMT65 turret the diameter limit becomes 11.75 in (298 mm).
The table for this model lists no live tooling, C axis or Y axis, so it is a turning machine only. In the same bed length the ST-20LY has ± 2 in (± 51 mm) of Y travel and live tools at 4,000 rpm, though with a 20 hp (14.9 kW) spindle and an 11.75 in (298 mm) turning diameter.
A 12-station BOT turret. Haas lists OD and ID tools in any combination, depending on the turret, and 4 in (102 mm) of rear clearance for boring bars. The table also quotes a maximum turning diameter of 11.75 in (298 mm) for a BMT65 turret, so that turret style is an alternative configuration.
A three-phase supply of 220 VAC at 70 A or 440 VAC at 35 A, and compressed air at 4 scfm and 100 psi (113 L/min at 6.9 bar), never below 80 psi (5.5 bar). Coolant capacity is 55 gal (208 L). The machine arrives on a 190 × 90 × 90 in (483 × 229 × 229 cm) pallet and weighs 12,000 lb (5,443 kg).
