The million of these units in use speak for themselves: they are a joy to use!

With a diameter of only 35mm it is unsurpassed easy to manage. Besides the weight of only approx. 230g, the effortless drive via balanced motor with ground spindle and collar bearing allows for quiet run with a pleasing sound to the ear. The high-quality MICROMOT steel collets ensure accurate clamping of the cutters, without rattling or vibrating of bits and cutters. The size of the machine dictates a 12V drive system, use of a mains adapter of at least 1.0A is thus required. We recommend MICROMOT mains adapters NG 2/S, NG 2/E or NG 5/E.

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).

Mill/drill unit MICROMOT 50

Without electronic speed control (continuously 20,000rpm).
Other technical specifications and design as the above mentioned MICROMOT 50/E.
