Haas Automation publishes a list price of US$88,995 for the Haas ST-30 (verified 2026-10-02). Options, tooling, freight and installation are extra, so a dealer quote will differ. A specific price can be requested at https://machinetoolindex.com/machines/haas-st-30#price; the request is passed to Haas Automation or an authorised dealer.
It raises spindle torque from the standard 300 ft-lbf (407 N·m) at 500 rpm to 1,000 ft-lbf (1,356 N·m) at 150 rpm. That is the torque needed to take heavy cuts on large diameters, where the spindle turns slowly. The gearbox is an option; the base machine has the standard 30 hp (22.4 kW), 3,400 rpm spindle.
Up to 15 in (381 mm) in diameter and 32.5 in (826 mm) long, with 21 in (533 mm) of swing. If a BMT65 turret is fitted the maximum turning diameter is 13.75 in (349 mm). Bar up to 3 in (76 mm) feeds through the spindle, and the chuck is 10 in (254 mm).
Length. The ST-30 has 32.5 in (826 mm) of Z travel and weighs 10,900 lb (4,944 kg). The ST-30L has 62.5 in (1,588 mm) of Z travel and weighs 13,300 lb (6,033 kg). Turning diameter, chuck, bar capacity and the 30 hp (22.4 kW) spindle are the same on both.
No, it is listed as an option. It has a 6.5 in (165 mm) chuck on an A2-5 nose, a 4,100 rpm top speed, a 2.31 in (58.7 mm) bore and rapids of 400 ipm (10 m/min), and it runs synchronised with the main spindle up to 3,400 rpm. The chuck throat is 1.81 in in diameter by 1.6 in deep (46 mm by 40.6 mm).
Haas lists WiFi, HaasDrop wireless file transfer, Safe Run and HaasConnect remote monitoring as standard on the ST-30. The two-stage automatic parts catcher, the sub-spindle and the automatic door are listed as options, so check which of them are on your quote.
220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A, plus 4 scfm of air at 100 psi (113 L/min at 6.9 bar) with no less than 80 psi (5.5 bar) at the inlet. Coolant capacity is 55 gal (208 L). It ships on a 171 × 90 × 98 in (435 × 229 × 249 cm) pallet.
