Universal Key Cutting Machine (Defu)

These machines are designed to duplicate keys for a variety of applications, including residential doors, padlocks, and automotive keys (depending on the model). They work by tracing the pattern of an original key and milling the copy. Many units feature manual controls for feed and speed, dual-sided clamps, and operate on 110V/220V power. They are known for being relatively compact, portable, and a cost-effective choice for key copying.
