Use this 2.1 mm Maillefer slot cutter to cut grooves, small cavities, and straight-walled recesses.
The slot milling cutter has a geometry that is very different from that of a ball-end mill: its cutting edge is more cylindrical and allows the material to be machined from the sides. In jewelry making, this type of bur is used in particular to carve or grind grooves, widen an opening laterally, rework an edge, or shape a small cavity whose walls must remain relatively straight. Cutters are rotating tools that remove material, and the cylindrical slot cutter is one of the classic shapes used by jewelers. It is also primarily used for setting stones or creating clean grooves on a metal plate.
What can you do with this 2.1 mm diameter?
Its width allows you to make fairly noticeable adjustments: creating a groove in a metal piece, smoothing the inside of an opening after cutting, preparing a small notch, or adjusting a cavity before assembly. It can also be used to rework certain elements made of resin or clay, depending on your project.

The slotted bit quickly removes material from its sides; therefore, it’s best to make multiple light passes rather than trying to reach the final depth all at once. Experienced designers will particularly appreciate this shape for precise finishing and adjustments.
