1/4 Drive Chuck with Collets

thingiverse

I designed this little drill bit holder for small drill bits. It features interchangeable collets that fit various sizes: 1/32, 1/16, 1/8, 1/4, and 3/8 (mainly for fun, since the 3/8 size might be too large). Each collet has a label to identify it easily. A handle is also included as an alternative way to hold drill bits by hand. It fits perfectly in my battery-powered bit driver. To use, find the collet that matches your drill bit and insert it into the holder. Then screw the parts together until they grip the drill bit securely. With this tool, you can drill freely, but be aware that high-torque drilling might not work well due to its plastic construction.
