Overview
Two capacities define the Haas ST-45L: a 7 in (178 mm) spindle bore and 80 in (2,032 mm) of turning length. It is a long-bed, large-bore lathe with a 35.5 in (902 mm) swing, turning up to 30 in (762 mm) in diameter at a maximum of 1,400 rpm.
The pairing matters for tubular work. A long pipe can run through the headstock for end machining, or sit between the chuck and the tailstock for work along its length, and one machine handles both. The tailstock has an MT5 taper, 84.5 in (2,146 mm) of travel and 200 lbf (890 N) to 3,000 lbf of thrust.
Through-spindle capacity needs care. The table lists an 18 in (457 mm) chuck as an option and quotes bar capacity as 6.5 in (165 mm) with optional workholding, matching the 6.5 in (165 mm) draw tube bore in the chuck kit rows. The bare spindle bore is larger than what that draw tube will pass.
The ST-40L is the same length with the same 29,900 lb (13,563 kg) weight, 40 hp (29.8 kW) and 1,400 ft-lbf (1,898 N·m) at 150 rpm, but it has a 4.62 in (117.3 mm) bore and runs to 2,400 rpm. Choose between them on what has to go through the spindle. On both, the bed length brings a slow Z rapid: 320 ipm (8.1 m/min) here, against 710 ipm (18 m/min) on X.
An XP option is listed with a 2-speed gearbox, 55 hp (41 kW) and 2,100 ft-lbf (2,847 N·m) at 150 rpm, drawing 105 A at 220 VAC or 53 A at 440 VAC. The domestic shipping pallet is 254 × 95 × 105 in (646 × 242 × 267 cm). Haas lists a starting price of US$257,995.

Strengths & Limitations
Strengths
- 7 in (178 mm) spindle bore combined with 80 in (2,032 mm) of turning length
- 84.5 in (2,146 mm) of tailstock travel on an MT5 taper
- 1,400 ft-lbf (1,898 N·m) at 150 rpm, or 2,100 ft-lbf (2,847 N·m) with the XP option
- 30 in (762 mm) maximum turning diameter and 20 in (508 mm) of X travel
- 9,000 lbf (40,034 N) of Z thrust for drilling and heavy facing
Limitations
- 1,400 rpm maximum, against 2,400 rpm on the ST-40L
- Bar capacity is 6.5 in (165 mm) and depends on optional workholding
- Z rapid is only 320 ipm (8.1 m/min) over 80 in (2,032 mm) of travel
- Weighs 29,900 lb (13,563 kg), so rigging and floor capacity must be checked

Frequently Asked Questions
01
The spindle bore is 7 in (178 mm) on an A2-11 nose. Bar capacity is given as 6.5 in (165 mm) with optional workholding, and the kit rows for the optional 18 in chuck show a 6.5 in (165 mm) draw tube bore and a 1,400 rpm maximum. The table gives no chuck size for the base machine.
02
In the headstock. The ST-40L has an A2-8 nose, a 4.62 in (117.3 mm) bore, a 15 in (381 mm) chuck, 4 in (102 mm) of bar capacity and 2,400 rpm. The ST-45L has an A2-11 nose, a 7 in (178 mm) bore and 1,400 rpm. Both turn 30 in (762 mm) by 80 in (2,032 mm) with 40 hp (29.8 kW), and the ST-40L is listed at the same 29,900 lb (13,563 kg).
03
Travel is 84.5 in (2,146 mm), longer than the 80 in (2,032 mm) Z stroke. The taper is MT5. Minimum thrust is 200 lbf (890 N) and maximum thrust is 3,000 lbf. Thin-walled tube needs the low end of that range to avoid being pushed out of round.
04
X travels 20 in (508 mm) at 710 ipm (18 m/min) with 5,500 lbf (24,465 N) of thrust. Z travels 80 in (2,032 mm) at 320 ipm (8.1 m/min) with 9,000 lbf (40,034 N). Z therefore has about 64% more thrust than X but moves at less than half the rapid rate.
05
The base rows are 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. The XP option rows are 105 A at 220 VAC or 53 A at 440 VAC. Air is 4 scfm at 100 psi (113 L/min at 6.9 bar), 80 psi (5.5 bar) minimum, and the coolant tank holds 95 gal (360 L).
