A set of three spindles for a bow drill. The shafts are cylindrical pieces of wood that taper towards rounded ends for fitting into drill bearings. Two of the spindles have iron bits inserted into antler socket pieces attached to the spindles and held in place with twisted sinew wrappings. The third spindle has an iron bit inserted directly into the end of the shaft, and also has a wrapping of twisted sinew. One of the spindle shafts has a lightly incised line that forms a spiral along its length.
