VEVOR CNC 3018 Pro CNC Router 300×180×45 mm CNC Machine 2.5W GRBL Control Mini Laser Engraver with Offline Controller 3 Axis Laser Engraving Machine for Carving Milling Plastic, Acrylic, PVC, Wood

I can see the Positioning Accuracy is quite sufficient: 0.003"-0.004" / 0.08-0.1 mm. However, is operating accuracy is the same? Will I be able to engrave/drill 2mm wide letters on a 1mm thick copper sheet? More than one pass is quite alright for me, I am just wondering if I can go through 1mm thick copper in a small space.

Does this CNC takes drills and chisels so it can penetrate wood? Or it’s just the laser ? Thank you
