Comparisons
CNC router comparisons, decided by material
Choose by material. A CNC router shapes wood, plastics and soft metals like aluminium. A laser excels at fine cutting and engraving of thin materials, plasma cuts thick metal fast, and a mill removes more metal with higher rigidity. The right pick is the machine matched to your main material and tolerances.
Most comparison content is written by sellers of one machine. These are decided by material and use, not by what we want to sell.
Router versus other machines
A router versus a mill comes down to rigidity and RPM: routers commonly spin 9,000 to 24,000 RPM and hold a few thousandths to a couple hundredths of an inch, while a mill runs a slower 3,000 to 10,000 RPM but its heavier frame routinely holds tolerances in the thousandths, the difference between furniture-grade work and parts that need to fit. A router versus a thickness planer is not really a rivalry at all: a planer thicknesses a board in seconds per pass, while a router can flatten a slab too, just an hour or more slower, using a wide surfacing bit and a flattening jig. Against a laser or plasma cutter, the deciding factor is thickness and material: lasers excel at fine cutting and engraving thin sheet, plasma cuts thick metal fast and roughly, and a router remains the only one of the three that carves, pockets and cuts joinery in wood and plastic.
Brand against brand
We also line up the specific machines buyers shortlist against each other, spindle for spindle and dollar for dollar, rather than repeating a spec sheet. When you have a winner, see real pricing in our cost guides, or check what to look for before buying.

FAQ
Frequently asked questions
- Should I buy a CNC router or a laser?
- A router suits three dimensional cutting and carving in wood, plastic and aluminium. A laser suits flat cutting and engraving, and only cuts metal at high cost. If you shape solid material, choose a router; if you engrave or cut thin sheet, a laser fits better.
- What is the difference between a CNC router and a mill?
- A router spins fast and is built for large, softer sheet work. A mill is heavier and more rigid for removing metal with tight tolerances. Routers cut aluminium with care, but sustained hard metal work calls for a mill.
