Your augur tool was used to penetrate a rubber automobile tire -- making a larger hole than the object that caused the tire to go flat. A second tool with a key-slot on the end was inserted into the newly drilled hole -- only after a nylon piece of cord that was knotted on one end and was coated with a resin. The cord and tool was inserted and withdrawn quickly and hopefully the tag end of the cord was pulled back through the drilled hold so the person fixing the tire could grab it with a pair of pliers. Once grabbed, the tag end was pulled until the knotted end was drawn up in the hole until it reached the inner tire wall. The tag end was then placed on fire with a cigarette lighter and allowed to draw a bead in the thread. Quickly extinguished, a glob of cord was embedded in the tire's thread. Put tire back on rim, fill with air pressure, and tubeless tire was repaired. That is an old tool -- my dad taught me how to use it in 1970 when he was 70-years-old. Worked pretty good for the DIY tire mechanic. Roger, thanks for the memory, and I am glad I could share what my dad taught me so many years ago. And, yes he was born in 1900.
