Haas Automation publishes a list price of US$141,995 for the Haas ST-35L (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-35l#price; the request is passed to Haas Automation or an authorised dealer.
Maximum turning length, Z travel and the distance between centers are all 62.5 in (1,588 mm). Maximum turning diameter is 15 in (381 mm) and swing is 21 in (533 mm). Stock up to 4 in (102 mm) can also pass through the 4.62 in (117.3 mm) spindle bore, so the part length is not limited to the bed when only one end is being machined.
Yes. Haas lists a programmable tailstock with a #4 Morse taper as standard and describes it as an improved tailstock design. What is optional is the steady rest provision, which Haas offers for part-face machining or for supporting extra-long parts. The spec table for this model gives no tailstock thrust or travel figure, so ask for those if a heavy part depends on them.
Both have a 12 in (305 mm) chuck, an A2-8 nose, 40 hp (29.8 kW), 425 ft-lbf (576 N·m) at 325 rpm, 3,200 rpm and 4 in (102 mm) of bar capacity. The ST-28L turns 13 in (330 mm) in diameter and 42.5 in (1,080 mm) long. The ST-35L turns 15 in (381 mm) and 62.5 in (1,588 mm).
Haas describes it as an extended pocket in the bulkhead that provides clearance for tools up to 30 in (762 mm) long, depending on workholding, and lists it as standard on this model. Long boring bars for tube and cylinder work are the obvious use: with 62.5 in (1,588 mm) of Z travel, bore depth is otherwise limited by the tool the machine can accept.
The table lists a 12-station turret that takes any combination of OD and ID tools, with 4 in (102 mm) of rear boring-bar clearance. A 12-station BMT65 turret is available as an option. With it, the maximum turning diameter is 13.75 in (349 mm) instead of 15 in (381 mm).
