Advantages
Haas DS-20Y
- 4,000 rpm spindle against 3,400 rpm
- Lower list price, US$163,995 against US$176,995
- Lighter machine at 11,240 lb (5,098 kg) against 12,700 lb (5,761 kg)
Haas DS-25Y
- 30 hp (22.4 kW) spindle against 20 hp (14.9 kW)
- 300 ft-lbf (407 N·m) against 150 ft-lbf (203 N·m) at 500 rpm
- 3 in (76 mm) bar capacity against 2.5 in (64 mm)
- 10 in (254 mm) chuck against 8.3 in (210 mm)
Verdict
Choose by bar size and material. The Haas DS-20Y suits fittings, connectors and couplings from bar up to 2.5 in, where 4,000 rpm and the lower list price fit small-diameter production. The Haas DS-25Y suits larger hydraulic and automotive parts from 3 in bar and tougher materials, where twice the torque and 30 hp keep heavier cuts productive.
