Another version of the spiral point plug tap is the spiral flute tap, whose flutes resemble those of a twist drill ...
The slip rings are attached to one part of the machine, and a set of fine metal brushes are attached to the other part. The brushes are kept in sliding contact with the slip rings, providing an electrical path between the two parts while allowing the parts to rotate about each other.
