The Dremel 7120 is an oval disc diamond abrasive bit designed for Dremel-type rotary tools, specifically for engraving, shaping and removing material on hard or fragile surfaces. It is particularly suitable when precision work is needed on resistant materials such as glass, ceramic or hardened metal, where a traditional cutter would perform less well or wear out quickly.
