Ideal for model builders, woodcarvers, jewelers, opticians, artists, dental technicians, tool and die makers, etc. Note: A mains adapter is required to operate the MICROMOT 60 devices. We recommend the PROXXON mains adapter NG 2/S. The speed control of our 12 volt devices only works when operated via nonstabilised power supply units (e.g. all MICROMOT mains adapters). Connection to stabilised power supply units is possible. However, the devices will then operate with maximum rotational speeds (also applies to operation with batteries).
