This Archimedes spiral push drill by Horotec is a simple yet useful tool for drilling by hand when you require a more precise application.  An Archimedean drill can be used in the same way as a pin vice, for holding small drill bits and hand-drilling holes. 

Use one-handed by simply pushing down on the top with your forefinger while working the central spiral up and down with your thumb and middle finger. This causes the drill to turn. Ideal when you need to drill delicate holes.

• Will hold drill bits up to and including 1.0mm
