The ultimate hand-cranked drill?
Posted: Wed Jun 26, 2019 6:21 pm
My son got this drill from somebody online. It has a two-position lever and a five-position slider.
The lever switches between low-speed gearing and high-speed gearing.
The slider has these functions:
1 "Normal" behavior. Chuck turrns clockwise when handle turned CW, chuck turns CCW when handle turned CCW.
2 Ratchets when handle turned CW; turns CCW when handle turned CCW.
3 Turns CW when handle tuirmed CW; ratchets when handle turned CCW.
4 Turns CW when handle turned CW or CCW.
5 Locks mechanism; won't turn at at all. (For tightening or loosening chuck.)
And each of those works at high speed or low speed gearing.
I especially like #4.
