How to Drill a Curved Hole

By Andrew Liszewski on at

Even if your carpentry skills aren’t much more than having watched a few episodes of Home Improvement, it’s still pretty common knowledge that a drill only works in a straight line. Or does it? Woodshop hacker Izzy Swan created a custom rig that can actually drill a curved hole instead.

By welding a drill bit onto the end of a flex shaft attached to a curved rig, Swan’s unorthodox creation allows a standard power drill to bore holes through wood that curve in any direction he needs. It’s useful for running wires and cables through inside corners of a new home under construction, but also because the idea will also melt your brain a little. [YouTube via Core77]
