The Archimedian Push Drill with Spring is an indispensable bench tool for jewelers and metalsmiths who need precise, controlled drilling with small twist drills. Designed around the ancient Archimedian screw principle, this hand-powered drill lets you start and drill holes with far greater accuracy than motor-driven tools — making it ideal for delicate work where a wandering bit or broken drill would be costly.
To use, place one thumb and finger on the swivel top while the other hand slides the knurled rotating rod up and down the twisted shaft. This push-and-release motion spins the bit at a speed entirely under your control, dramatically reducing the risk of drill breakage or drift from your center punch mark. The return spring automatically resets the rod for the next stroke, keeping your workflow smooth and efficient.
