ship auger

I can recall no life-affirming lessons, however, from the ship auger bit that I discovered the other day in a crowded bin.

Also available: 16mm x 770mm STAR M Ship Augers are hardened, greatly increasing bit life and time between sharpening.

He combined these ideas by building the Turtle which was designed to attack ships by attaching a time bomb to their hulls, while using a hand powered drill and ship auger bit to penetrate the hulls.
