This is a 3D Printed hand drill with adjustable Chuck for drilling in PCB,Wood or any plastic surface. This slightly beefier version features an adjustable chuck that can handle bits from 5mm (3/16″) down to 1.5mm (1/16″). The end of the bit seats in the conical shaped chuck cavity, and the flexy fingers at the tip grab further up the shank. You get 2 full rotations per stroke for fast drilling. It also works as a pin vise for holding needle files.
INSTRUCTIONS TO USE:
To assemble, first push the slider onto the body. Next, put a little dab of grease on the end nub pin and click it onto the end of the drill body. It should spin freely. Finally, put a little bit of grease on the chuck threads and also on the outside of the tips of the flexy fingers and then screw on the chuck.
To use, insert your bit (1.5 to 5mm) into the chuck until the end of the bit hits the bottom of the conical chuck cavity. Then tighten the chuck just enough so you can’t rotate the bit with your fingers. Do not over-tighten – the flexy fingers will break! This drill works best with very light downward pressure and a little patience. (Tip: to drill larger holes, start by drilling a smaller pilot hole.)
