Haas Automation publishes a list price of US$120,995 for the Haas ST-28L (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-28l#price; the request is passed to Haas Automation or an authorised dealer.
The ST-28L has the larger bore: 4 in (102 mm) of bar capacity and 425 ft-lbf (576 N·m), with a 13 in (330 mm) turning diameter over 42.5 in (1,080 mm). The ST-30 and ST-30L take 3 in (76 mm) bar and turn 15 in (381 mm), at 32.5 in (826 mm) and 62.5 in (1,588 mm) of length. X travel is 9.4 in (239 mm) on all three.
The spindle bore is 4.62 in (117.3 mm) and bar capacity is 4 in (102 mm), on an A2-8 nose with a 12 in (305 mm) chuck. The spindle is rated 40 hp (29.8 kW) with 425 ft-lbf (576 N·m) at 325 rpm and a 3,200 rpm maximum.
Not as listed. Its table has X and Z only, with no live-tool or C-axis rows. The ST-28LY is the same bed length with ± 2 in (± 51 mm) of Y travel and live tools at 4,000 rpm; it turns 11.75 in (298 mm) in diameter and weighs 12,700 lb (5,760 kg).
The table lists a 12-station BOT turret that accepts OD and ID tools in any combination, depending on the turret, with 4 in (102 mm) of rear clearance for boring bars. It gives a second turning diameter of 11.75 in (298 mm) for a BMT65 turret, against 13 in (330 mm) otherwise.
Power is 220 VAC three-phase at 70 A or 440 VAC at 35 A. Air is 4 scfm at 100 psi (113 L/min at 6.9 bar), minimum 80 psi (5.5 bar). The machine weighs 12,000 lb and ships on a 190 × 90 × 90 in (483 × 229 × 229 cm) pallet, so check door openings and forklift or crane capacity.
