These are carbon brushes with manufacturer quality. These have a spring with a so-called cut-off element integrated on one side. At about 80% wear of the brush is thus achieved an automatic shutdown. If this is not done, then the brush holder can permanently damage the collector. Therefore, always make sure to purchase this spare part exclusively from the manufacturer as an original spare part.
very helpful, thanks
I disassembled my Kress FME1050, and there is a hole inside of a graphite with spring in it? I've never seen that before. Is it a wear indicator?

I thought so. Thanks
