Archimedes would have been truly proud of this tool. The mechanism consists of a central helical shaft and a spring-loaded sliding collar. Moving the collar up and down causes the shaft to rotate approximately one and a quarter times. The drill will hold bits up to 1.0mm diameter in a collet at the head of the drill. At the other end is a swivelling finger rest. Small but effective and well made. Overall length 110mm.
