🔧 What it does & how to use

These fine twist bits are made for drilling tiny, precise holes in jewellery, watch and clock components, and other small craft materials — ideal for hobbyists and jewellery makers who need a range of small diameters on hand.

• Select the bit: choose the size that matches the hole you need, from 0.30mm up to 1mm.
• Fit the bit: insert it into a pin vise or the chuck of a mini/hand drill and tighten securely.
• Secure the workpiece: hold or clamp the material steadily to keep it from shifting while drilling.
• Drill gently: apply light, even pressure and let the bit cut — these are fine HSS bits and can snap under heavy force.
• Clear debris: withdraw periodically to clear swarf and keep the hole clean, especially on deeper drilling.
