Overview
The Haas GM-1XT-5AX is the extended-table version of the GM-1-5AX gantry mill. X-travel grows from 3,073 mm to 3,613 mm (121 to 142 in) and the table stretches to 3,664 x 1,346 mm (144.3 x 53 in). Everything else carries across unchanged: the 24,000 RPM 15 hp spindle, 1,549 mm (61 in) of Y, 610 mm (24 in) of Z and 800 ipm rapids.
Twenty-one extra inches sounds marginal until you're trimming a panel that's 130 inches long. Large aerospace skins, marine components and full-length patterns either fit or they don't, and for shops working at that scale the XT is the only version worth considering.
US$339,995 is a US$40,000 premium over the standard GM-1-5AX. That's a lot of money for length alone, so the decision should come down to a straightforward measurement of your longest part rather than a general preference for more capacity.
The machine's character is unchanged, which means the same caveats apply. 14.9 Nm (11 ft-lbf) of spindle torque restricts it to composites, aluminium, patterns and soft materials. Twenty-four inches of Z keeps it to relatively flat work. Bought for what it's designed to do, it's effective; bought as a general-purpose large 5-axis machine, it will disappoint.

Strengths & Limitations
Strengths
- 3,613 mm (142 in) of X-travel handles full-length aerospace skins and marine panels
- 3,664 mm (144.3 in) table length gives usable fixturing space across the whole envelope
- 24,000 RPM spindle and 800 ipm rapids suit high-speed trimming of light materials
- 5-axis motion allows contour trimming of formed parts without repositioning
- 2,722 kg (6,000 lb) table load supports large trim fixtures and vacuum tooling
Limitations
- US$40,000 over the standard GM-1-5AX buys length only, with no gain in power, Y or Z
- 14.9 Nm (11 ft-lbf) spindle torque excludes steel roughing
- 610 mm (24 in) Z-travel limits it to relatively flat components
- Footprint is substantial and grows with the extended table, so floor planning matters
- Specialist composite gantry builders offer better integrated dust and vacuum systems

Frequently Asked Questions
01
Haas lists US$339,995 as of August 2026, roughly US$40,000 above the standard GM-1-5AX. Extraction and vacuum fixturing for composite work are additional.
02
Only if your parts need it. The XT adds 21 inches of X and nothing else. Measure your longest component against the 121-inch standard machine first, because that's the entire decision.
03
Composites, aluminium sheet and panel, tooling board, foam and patterns. The 24,000 RPM spindle produces 11 ft-lbf, which is a high-speed light-cutting arrangement rather than a metal-removal one.
04
For composite and tooling-board work, effectively yes. Machining carbon fibre and board produces abrasive dust that damages ways and bearings without proper extraction, and most installations budget for it from the start.
