Effectively round the ends of your wires with this Maillefer 1.2 mm-diameter steel bell cutter.
This 1.2 mm diameter Maillefer steel bell-shaped file is designed to smooth and round off the ends of metal wires after cutting. It removes sharp edges and improves comfort when worn, while giving your jewelry a more professional finish. Its 1.2 mm diameter is suitable for medium-gauge wires, often used for the structures of rings, bangles, hooks, or decorative findings. You can use it by attaching it to a rotary tool such as a Dremel to achieve faster, more consistent rotation—ideal for batch production or repeated finishing.
What can you do with this bell-shaped drill bit?
For DIY projects, this bit is particularly well-suited for securing the ends of wire used in open bangles, handmade hoop earrings, or rigid wire rings. It’s designed for use with 1 mm diameter metal wire. By rounding off each end, you prevent snags on skin or clothing and significantly improve the perceived quality of your creations. This tool is an essential ally for minimalist jewelry and wire-wrapped pieces where precise finishes make all the difference.
Size Selection Tip:
For best results, choose a drill bit with a diameter 0.1 to 0.2 mm larger than that of your wire.
Example: For 0.8 mm wire, choose a 0.9 mm or 1.0 mm drill bit.
A drill bit the same size as the wire will prevent it from entering the bell. A drill bit that is too large will cause the tool to slip and may deform the wire.
