Haas Automation vs Haas Automation · Vertical Machining Centers
Summary
The Haas DT-2 and Haas DT-3 are the same 30-taper drill/tap machine in two table lengths. Both have 16 in (406 mm) of Y travel, 15.5 in (394 mm) of Z travel, a 10,000 rpm, 15 hp (11.2 kW) BT30 spindle, a 20+1 tool changer, 1.75 s tool changes and 2,400 ipm (61 m/min) rapids. The headline difference is X travel: 28 in (711 mm) on the DT-2 against 36 in (914 mm) on the DT-3.
The DT-3 pairs that longer stroke with a 38 × 15 in (965 × 381 mm) table against 34 × 15 in (864 × 381 mm), at 5,860 lb against 5,350 lb (2,427 kg). Table load is the same 250 lb (113.4 kg) on both. Haas lists the DT-2 at US$70,995 and the DT-3 at US$75,995.

Advantages
Haas DT-2
- Lower published list price, US$70,995 against US$75,995
- Lighter machine at 5,350 lb (2,427 kg) against 5,860 lb
Haas DT-3
- 36 in (914 mm) of X travel against 28 in (711 mm)
- Longer 38 × 15 in (965 × 381 mm) table against 34 × 15 in (864 × 381 mm)
- Room for an extra vise or fixture station along X
Verdict
The spindle, tool changer and cycle times are identical, so the choice comes down to part length and fixturing. Buy the DT-3 if you run long extrusions or want two or three vise stations along its 36 in (914 mm) X axis. Buy the DT-2 when parts fit within 28 in (711 mm) of X travel and the lower US$70,995 list price matters more than the extra table length.
