One of my DeWalt cordless drills, one that is by my side so much I

ServiceNet shows motor brushes as available for the drill. They are
not easily removed, so I haven't looked at them yet. I've never had
to replace brushes in a power tool, so I'm not familiar with the
symptoms bad brushes might display.

Before I tear down a working drill and order $20 worth of parts, does
it sound like I need to replace the brushes?


Yep...you have now observes the classic symptoms.

I'd recommend checking them asap if you like the drill to make sure they
aren't so worn down that the holders are eating up the armature or new
brushes won't last 'cause they'll get chewed up...
