STEPCRAFT CNC systems are multifunction! Equipped with the right CNC tool, you can use your CNC machine for milling, engraving, 3D printing, CNC cutting and many more. The CNC tools can be easily exchanged which takes no time at all. Just loosen the quick release lever on the 43 mm tool holder, mount a new CNC tool and tighten the lever. This allows you to use your CNC router to create wood deco and personalized key rings, cut leather, engrave pendants, 3d print boats or make a cardboard box house.
