Advantages
Haas SB-35
- More spindle power at 29.8 kW (40 hp) for aggressive material removal in harder materials
- Superior spindle torque at 542 Nm (400 ft-lb) @ 500 RPM vs 102 Nm (75 ft-lb) @ 1,300 RPM
- Superior chuck size at 305 mm (12 in) vs 165 mm (6.5 in)
- Superior bar capacity at 89 mm (3.5 in) vs 44.5 mm (1.75 in)
- Superior max cutting diameter at 406 mm (16 in) vs 305 mm (12 in)
Haas ST-10
- Higher maximum spindle speed of 6,000 RPM enables faster cutting on aluminum and non-ferrous materials
- Superior rapid traverse x at 30.5 m/min (1,200 ipm) vs 10.2 m/min (400 IPM)
- More competitive pricing at $45,000 - $75,000 compared to $90,000 - $115,000
Verdict
The Haas SB-35 holds a spec advantage in this comparison, but the right choice depends on your shop's priorities. If the Haas SB-35's strengths in areas like Spindle Power and Spindle Torque align with your work, it's the clear pick. The Haas ST-10 may still win on dealer proximity, existing tooling compatibility, or specific features that matter most to your applications. Request quotes from both dealers and, if possible, run your actual parts on each machine before deciding.
