Churn drill

The churn drill is a large drilling machine that bores large diameter holes in the ground. In mining, they were used to drill into the soft carbonate rocks of lead and zinc hosted regions to extract bulk samples of the ore. They were common in the Tri-State areas during the lead and zinc mining in Missouri, Oklahoma, and Kansas.

There is an example of one of these machines at the Northern Life Museum in Fort Smith, Northwest Territories, Canada. It was used in 1929-1930 at the Pine Point lead and zinc mine in the Northwest Territories.
