🔧 What it does & how to use

A pin vice like this gives fine, controlled hand-drilling for small components — perfect for watch and clock repairers, model makers and jewellery crafters working with drills up to 1mm. The spring-loaded spiral (Archimedes) mechanism converts a simple downward push into a spinning action, so you get smooth, repeatable rotation without needing a powered drill.

• Fit the bit: Insert your chosen drill (up to 1mm) into the chuck at the tip.
• Secure it: Tighten the chuck so the bit is held firmly and runs true.
• Position the work: Hold the piece steady and place the drill tip on your marked point.
• Drill: Press down on the top handle — the spiral spring will spin the chuck and bit as you push.
• Repeat the stroke: Let the spring return the handle and push down again, working the hole to depth with light, even pressure.
