These five drills were part of a large collection of lithic material from a camp site in Allen County that was occupied periodically from the Archaic to the Early Ceramic Periods. They were donated to the Kansas Historical Society in 2015. Drills were used to bore holes in softer material than the drill itself, such as hides, shell, wood, or soft stone. The drill on the far left was possibly modified (reworked) from a Dalton projectile point. The drill on the far right was reworked from a corner notched dart point.
