tooljoe Posted November 27, 2011 Report Share Posted November 27, 2011 after a while of using your power tool, the commutator might need a little resurfacing to bring it back to it's best original performance. now that power tools are coming out with out canned motors, it is way easier to maintain the commutator/motor. so here are the basics of how a commutator should look and not look... anyways, this is how i resurface the commutator to one of my dewalt drills... just apply slight pressure with the filler while turning by hand. the same process can be similar to the other power tools... just sharing.
