Haas Automation publishes a list price of US$227,995 for the Haas ST-40L (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-40l#price; the request is passed to Haas Automation or an authorised dealer.
Maximum turning length and Z travel are both 80 in (2,032 mm), at up to 30 in (762 mm) in diameter. The ST-40 turns 44 in (1,118 mm) and the ST-40S 28 in (711 mm) at the same diameter, so the L is the model for work that outgrows those beds.
710 ipm (18 m/min) on X and 320 ipm (8.1 m/min) on Z. The Z figure is the one to note. A full-stroke move over 80 in (2,032 mm) at that rate takes long enough to show up in the cycle time, so keep tool-change positions close to the cut when programming long parts.
An MT5 taper, 84.5 in (2,146 mm) of travel, and thrust between 200 lbf (890 N) and 3,000 lbf (13,345 N). Travel exceeds the 80 in (2,032 mm) Z stroke, so the tailstock can reach parts anywhere along the turning length.
Spindle output and current draw. The base figures are 40 hp (29.8 kW) and 1,400 ft-lbf (1,898 N·m) at 150 rpm on a 70 A, 220 VAC or 35 A, 440 VAC supply. The XP rows give 55 hp (41 kW) and 2,100 ft-lbf (2,847 N·m) at 150 rpm through a 2-speed gearbox, on 105 A at 220 VAC or 53 A at 440 VAC. Maximum speed stays at 2,400 rpm.
Machine weight is 29,900 lb (13,563 kg). The domestic pallet is 254 × 95 × 116 in (646 × 242 × 295 cm) and the export crate 254 × 96 × 120.5 in (645 × 244 × 306 cm). Those are shipping sizes. Ask Haas for the installed layout before marking out the floor.
