The Makita Carbon Brush Set is the authentic replacement carbon brush assembly designed for the Makita CB-303 4"In Marble Cutter and compatible Hitachi/Hikoki power tools. Carbon brushes are key wear parts that transfer electrical current from a tool’s stator to its rotating armature. Over time, these brushes wear down due to friction and electrical load, which can cause reduced power, sparking, intermittent operation, or motor issues.

Size - 15 x 11x 5MM.
Usage - used for Makita 4"In Marble Cutter.
