Carbon Brush Set for Dremel Model 398 / 400 2610907940

Carbon Brush Set to suit Dremel Models 398 / 400 - Dremel Part # 2610907940 

They go under the brush cap and rest on the armature, providing the electrical connection to keep the tool running. These easily replaceable accessories also help extend the life of the tool.

You should check both motor brushes after every 50-60 hours of use. Simply unplug the tool, open the brush caps and remove the carbon piece from the holder. If there is less than 3.2mm of carbon left on either brush, they both should be replaced.

You may need to pry these out with either the collet spanner or a thin blunt screwdriver. No force is needed when doing this and they should just pop out.
