Some Special Types of Carbon Laminated Brushes
Fluted Brushes
Most of the times large machines are installed with fluted brushes in order to minimize the need of getting a good brush fit and commutator film. It is not necessary that along with the replacement brushes, fluted brushes are to be installed as well. Foremost advantage of using a fluted brush for replacement is that it will decrease the probability of damaging the commutator film surface.

These brushes fit in the brush holder in order smooth out the commutator ring as the machine works. Keep in mind that these brushes does not prove to be a bottleneck for the machine because they are made up of a material which is compatible with other brushes.
