Cleanly round the ends of your wires with this Maillefer 1 mm-diameter steel bell cutter.
This Maillefer steel bell-shaped file, with a diameter of 1 mm, is a precision finishing tool designed to round off wire ends and achieve a clean, snag-free finish. It smooths out sharp edges after cutting with wire cutters, improving the comfort of your jewelry and enhancing its perceived quality. Its compact size and fine diameter make it particularly useful for metal wires used in jewelry making (tubes, pins, brass, copper, and silver wire, etc.), as well as for small pieces requiring a meticulous finish. You can attach it to a Dremel to increase the rotation speed and achieve a cleaner result than when working by hand.
What can you do with this bell-shaped bit?
For DIY projects, this bit is ideal for preparing posts for earrings, rounding the ends of an open bangle, or achieving a cleaner finish on handmade rings. It also helps you refine wirework elements: wire rings, filigree pendants, hooks, DIY findings, and more. By incorporating it into your routine, you’ll achieve greater consistency and a more “professional” result, especially on minimalist pieces where every detail stands out.
Tip for choosing the right size:
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’s too large will cause the tool to slip and may deform the wire.
