🔧 What it does & how to use

This set covers the full range of fine sizes needed for delicate drilling in metal, wood and plastic — ideal for jewellery making, model making, hobby crafts, and watch or clock repair work where standard drill bits are too large. Each bit is held securely in the case by size, from 0.3mm up to 1.5mm in small increments.

• Choose the size: pick the bit matching the hole diameter you need from the case.
• Fit the bit: insert it into a pin vice or a mini rotary tool chuck and tighten securely.
• Mark the point: use a centre punch or scribe to stop the tiny bit wandering on the surface.
• Drill gently: apply light, steady pressure at a slow, controlled speed, letting the bit do the work.
• Clear debris: withdraw periodically to clear swarf and keep the bit running true.
• Return to case: store the bit back in its labelled slot after use to keep the set organised.

⚠️ Please check these are very fine, delicate bits that can snap easily under excessive pressure or side-load — use a slow speed, light pressure, and a bit suited to the material for best results.
