That is called a Brace and Bits… the older ones are superior to anything made today. The bits are called auger bits and range in size from tiny 1/8″ inch all the way up to massive 3″ wide augers. They make short work of drilling through wood. They are more than worth the money spent on buying a pristine example. The Stanley Braces had a ratchet in them. The bits came in a fitted wooden box, with each bit’s place marked.
The wicked flee when none pursueth..." - Proverbs 28:1
