The affordable Foredom® H.20D is ideal for close-in, precision jewelry work such as prong-setting or seat-cutting. Designed with an ergonomic, slim grip for comfortable handling, the tapered sides give users an easy-to-control, almost pencil-like hold. Change out burs in seconds by swinging the release lever 90°, removing and replacing the bur, and then swinging the lever backward or forward to secure the new bur. Factory-installed collet holds and 3/32" shank.
