"Aliens" by William McFee
Muttering to himself, he next took a powerful ratchet drill, and for a long time worked with it on the mine, boring a tiny but deep hole.
"Signal in the Dark" by Mildred A. Wirt
The drill-bar is rotated by means of a ratchet operated by a spiral groove in the shield of the machine.
