This bifacial drill is made from metavolcanic stone, and was recovered from the Hardaway site (31St4), Stanly County, North Carolina. The precise age of the drill is unknown, but it likely dates to the Archaic period, ca. 1000-8000 BP.
Bifacial stone drills were found in many stone toolkits in North American prehistory. Often they were made from bifaces like this one, but in many cases they were made from notched or stemmed bifaces with the same distal morphology as the points and knives in the toolkit. They were usually shaped by pressure flaking. Drills were used to perforate organic materials or to drill holes in stones.
The artefact is curated in the North Carolina Archaeological Collection, Research Laboratories of Archaeology, University of North Carolina at Chapel Hill.
