The Xtool F1 Ultra: When a Dual-Laser Makes Sense (And When It Doesn't)

So you're looking at the Xtool F1 Ultra. Maybe you've seen the videos of it cutting thin steel, or engraving a Yeti cup. That's what caught my eye too. But as someone who manages purchasing for a small metal fabrication shop—roughly $80k annually across 15 vendors—I've learned the hard way that marketing demos are not the same as a production workflow.

I'm going to skip the sales pitch. Instead, let's talk about what this machine actually is, what it isn't, and where it fits in a real workshop. Because if you're thinking about using an Xtool F1 Ultra to cut metal, or you're confused about the laser type, or you're comparing it to a pulse laser cleaner for welding steel, you need straight answers.

The Machine: What It Is, and What It Isn't

The Xtool F1 Ultra is not a 400W fiber laser. It's a 20W Fiber & Diode dual laser. That's its core advantage: one laser source for metals (the 20W fiber laser) and one for organics (the 20W diode laser).

What it does well:

• Engraving on metals: steel, aluminum, stainless steel. The fiber laser part handles this nicely.
• Cutting thin materials: paper, cardboard, wood, acrylic up to a few mm. The diode laser is for this.
• Cutting very thin metal: think 0.5mm steel or aluminum. It's not fast, but it works.
• Engraving curved surfaces: the included rotary attachment is a genuine time-saver.

What it is not:

• A pulse laser cleaner for removing rust or paint from thick steel. That's a different tool.
• A laser welder for joining steel plates. That's a completely different class of machine.
• A production-level laser for cutting 3mm steel. You'd be disappointed.

I didn't always understand these limitations. When I first saw the marketing—"laser engraver and cutter for metal"—I thought, "Great, we can replace our plasma cutter for small bracket work." That was a mistake.

When I compared the Xtool F1 Ultra side by side with a piece of 2mm steel, I finally understood why the details matter so much. The machine could engrave it beautifully. It could not cut it. Not in any reasonable timeframe. That's not a flaw; it's physics. A 20W fiber laser simply doesn't have the power to melt through thick steel.

The Laser Type: Why It Matters

The Xtool F1 Ultra uses a 20W fiber laser and a 20W diode laser. This is important because many people ask, "Does a pulse laser cleaner work for cutting metal?" No. A pulse laser cleaner is for surface cleaning, not cutting. This machine is for engraving and light cutting.

If your primary need is to cut thick steel or join steel via welding, you don't want a laser engraver. You want a laser welder or a plasma cutter. But if you need to mark batch numbers on steel handles, engrave logos on aluminum parts, or cut custom gaskets from thin rubber, this machine is a good fit.

I only believed this distinction after a painful experience. A vendor recommended a "laser cleaner" for our rust removal needs on structural beams. It was a different machine entirely—a handheld pulse laser. I didn't listen. I thought, "A laser is a laser." The machine we bought was the wrong tool, and it ended up costing us $2,400 in wasted time and return shipping.

How It Compares to a Pulse Laser Cleaner or Welder

These are different tools for different jobs. Let's make it clear:

• Xtool F1 Ultra: For engraving and cutting thin metals and organics. Fine detail. Desktop footprint.
• Pulse Laser Cleaner: For removing rust, paint, or coatings from thick metal surfaces. Handheld. No cutting ability.
• Laser Welder: For joining metals. Powerful. Joins plates. Not for engraving.

They are not interchangeable. If you need to weld steel, does plasma cutter need gas? Yes, a plasma cutter uses compressed gas (usually air) to cut. A laser welder typically doesn't need assist gas in the same way, but it's a different process altogether.

I've made the mistake of trying to use one tool for everything. In 2023, I consolidated all our cutting needs into a single CO2 laser machine. It was a disaster. The laser couldn't touch steel, and I had to buy a plasma cutter anyway. The lesson: choose the right tool for the job.

For the Xtool F1 Ultra, the job is precision marking and light cutting of small metal parts, plus engraving on wood and acrylic. It's a versatile secondary tool, not a primary production machine for heavy metalwork.

Should You Buy the Xtool F1 Ultra?

I recommend the Xtool F1 Ultra if:

• You need to engrave serial numbers or logos on metal parts—steel, aluminum, stainless steel.
• You want to cut custom shapes from thin brass, aluminum, or steel sheets (think 0.5mm or less).
• You need a dual-purpose machine that handles both metal and organic materials without swapping heads.
• You value a compact, integrated design with features like air assist and a rotary attachment built-in.

I do not recommend it if:

• Your primary need is cutting thick steel (1mm+). Get a plasma cutter or a higher-power fiber laser.
• You need to weld steel. Get a laser welder or a traditional TIG welder.
• You want to remove rust or clean surfaces. Get a pulse laser cleaner.
• You need high-volume production cutting of any material. This is a batch or prototype tool.

There's no one-size-fits-all. This machine works for a specific set of problems: small-scale, mixed-material, precision work. If that's your workflow, it's excellent. If you're the other 20% of use cases—heavy metal cutting, welding, or surface cleaning—look elsewhere.

If you want to know more about how it handles a specific material, drop a comment. I've probably tested it—or made the mistake of not testing it first.
