Quick Answer: ComMarker makes nothing but fiber and UV lasers, so every model — like the B6 20W (about $1,599) — is a dedicated, no-compromise metal marker for jewelry, tumblers, and tool tags. xTool builds diode, CO2, and fiber machines, and only its dual-laser F1 Ultra (~$1,999) can touch bare metal at all, but that same machine also carries a 20W diode for wood, acrylic, and leather. ComMarker wins on price and focus if metal is your whole business; xTool wins if you need metal marking alongside general crafts in a single machine.

ComMarker and xTool rarely compete for the same buyer directly, because they’re built around different bets: ComMarker bets everything on metal, xTool spreads its lineup across materials. This guide puts ComMarker’s fiber specialists against xTool’s broader range — and the one xTool model that actually overlaps with ComMarker’s territory — so you know which brand fits the jobs you actually have.

ComMarker vs xTool by the numbers

Metal marking: ComMarker’s whole business, xTool’s one model

If bare metal is the job, ComMarker is the more dedicated tool. Every model it sells — the compact B6 20W (~$1,599) up through the production-grade B4 100W MOPA (about $6,299) — is a fiber or UV laser built around nothing else, with touchscreen auto-focus, up to 15,000mm/s marking speed, and a roughly 100,000-hour rated laser life. We rank the full lineup in our best ComMarker laser engraver guide.

xTool’s answer is narrower: only the F1 Ultra (20W fiber + 20W diode, ~$1,999) can touch bare metal at all. Every other xTool — the S1, F1, P2S, M1 Ultra, and the discontinued D1 Pro — is diode or CO2 and can only mark coated or anodized metal with a spray, not engrave bare steel or brass directly. The F1 Ultra costs about $400 more than ComMarker’s entry B6, but that premium buys a second, fully independent diode laser in the same enclosure — not just a faster or more precise fiber source.

Everything else: xTool covers it, ComMarker doesn’t

Flip the question to wood, acrylic, or leather, and the lineup reverses completely. xTool’s diode machines — the S1, F1, and M1 Ultra — cut and engrave those materials natively, and even the metal-capable F1 Ultra carries its own 20W diode for exactly that purpose. Need serious cutting depth on thick stock? The 55W P2S CO2 handles that too, something no ComMarker model attempts. See our best xTool laser engraver guide for the full range.

ComMarker has no answer here at all. A fiber beam leaves a shallow surface mark on wood or leather but can’t cut through it, and does nothing useful on clear acrylic — ComMarker’s own documentation is upfront that its lineup is metal-only. A shop running wood signs alongside metal tags needs a diode brand in addition to a ComMarker, not instead of one.

Best ComMarker: the dedicated metal specialist

ComMarker B6 20W

Best ComMarker for metal marking · ~$1,599
  • 20W fiber (1064nm), 150mm x 150mm work area, touchscreen auto-focus.

If you already run an engraving business, a free Amazon Business account unlocks quantity discounts and tax-exempt purchasing on the marking spray, blanks, and lens caps either brand’s fiber laser goes through fast.

The B6 20W is the machine to buy if metal marking is the whole job, no exceptions. It’s genuinely compact for an industrial-grade fiber laser, and its dual LightBurn/EZCad2 support means you’re not locked into one control app. See our full ComMarker B6 vs B4 ranking if you need the handheld B4 instead, or higher MOPA wattage for color-marking.

Best xTool: the dual-laser generalist

xTool F1 Ultra (20W Fiber + 20W Diode)

Best xTool that also marks metal · ~$1,999
  • Only xTool with a fiber laser — deep-engraves bare stainless, brass, gold.
  • Second, independent 20W diode handles wood, acrylic, and leather.
  • Galvo speed up to 10,000mm/s (per xTool); compact enclosed body with auto-focus camera.

The F1 Ultra is the only xTool worth cross-shopping against ComMarker directly, because it’s the only one that competes on the same bare-metal turf. The roughly $400 premium over the ComMarker B6 buys a second laser, not just a different fiber source — if your catalog mixes metal tags with wood or acrylic items, this is the machine that replaces two single-purpose lasers with one. For materials other than bare metal, our full xTool laser engraver ranking covers the diode-only S1, portable F1, and CO2 P2S, none of which compete with ComMarker at all.

How to choose between ComMarker and xTool

The bottom line

ComMarker and xTool aren’t really fighting for the same buyer most of the time — ComMarker’s entire catalog bets on being the best dedicated metal marker, while xTool spreads its lineup across diode, CO2, and one dual-laser fiber machine. If bare metal is your whole business, ComMarker’s B6 20W is about $400 cheaper than the only xTool that can do the same job. If your catalog mixes metal with wood, acrylic, or leather, the xTool F1 Ultra is the one machine on either side built to cover all of it at once. New to the category?
