Cole drill handle

thingiverse

The hex of the feed screw on the Cole ratcheting drill is a bit uncomfortable to use. It has sharp edges that can start to cut into the hand while turning. I made a handle that slides over the hex. It's a little bit bigger and rounded so it's easier to turn. The ratcheting assembly unscrews from the shaft. Clamp the sprocket in a vice and turn the chuck. The handle slides on and then the ratchet keeps it in place. The shaft is has 1/2-13 threads. I screwed on a coupling nut and used a socket in a drill to drive it. It makes drilling faster and easier. I've included the Fusion 360 model.
