Advantages
Haas DS-25Y
- 300 ft-lbf (407 N·m) torque against 275 ft-lbf (373 N·m)
- Lower list price, US$176,995 against US$183,995
Haas DS-30Y
- 32.5 in (826 mm) turning length against 22.5 in (572 mm)
- 13.75 in (349 mm) turning diameter against 11.75 in (298 mm)
- 4,500 rpm spindle against 3,400 rpm
- 9.4 in (239 mm) X travel against 8.4 in (213 mm)
Verdict
Choose the Haas DS-25Y for hydraulic and automotive fittings from 3 in bar that fit 22.5 in of turning length, where its 300 ft-lbf and lower list price suit the work. Choose the Haas DS-30Y when part families run longer or larger, up to 32.5 in long and 13.75 in in diameter, or when the 4,500 rpm spindle helps small-diameter finishing.
