💡 Why do carbon brushes wear out faster than other electrical contacts in rotary tools?
These graphite contacts handle constant friction against the rotating commutator bar, which wears them down over time. Swapping them out is a handy fix that stops power loss and brings your gear back to factory output levels.
- Match original copper lead dimensions and spring tension settings before you order replacements
- Clean the commutator grooves thoroughly to prevent arcing and extend the life of the new set
- Install fresh graphite blocks evenly to maintain proper rotational balance during heavy load tasks
