Uolor 3-Speed Cordless Mini Drill Pen 30 min

The Uolor cordless mini drill pen is a compact rechargeable tool for delicate DIY tasks such as jewellery making and resin keychains. It combines portability with adjustable speed so you can work on small materials with control and minimal fuss.

Key features

This lightweight pen-style drill offers three adjustable speed levels from 5 000 to 18 000 r/min, letting you match power to the material. It charges by USB and provides about 30 minutes of cordless use after a full charge, which is handy for short sessions away from a mains socket. The set includes ten small drill bits with diameters from 0.6 mm to 2.2 mm, covering common micro drilling needs. It has built-in overload protection and a safety circuit to cut power if resistance becomes excessive, according to the manufacturer.

Getting the most from it

Use lower speeds for delicate materials like resin, shell or thin plastic and increase speed for harder surfaces such as ceramic or wood. Keep bits clean and change them gently to avoid wobble. If you prioritise portability and precision over long runtime, this is a compact option to consider. It’s a good fit if you make small batches of jewellery or repair keychains and want a lightweight, easy to carry tool.

Care & maintenance

Store the drill and bits in a dry case and charge before long periods of storage to preserve battery health. Avoid forcing the tool through dense material, as the overload protection can cut power during heavy use. Clean bits after use to maintain cutting performance.
