I fix cordless DeWalt drills every week!Look for two black carbon-like blocks found on either side of the commutator ( the central spindle ) they will each have one wire on the outside end attached to a spade connector so the brush can be easily removed by prying it out from beneath the spring holding the brush against the commutator.  Then the wire can be removed and the new brush installed.    Go online to http://www.toolpartsdirect.com and search for your model dewalt drill. they have an exploded diagram and parts listing for each model drill.  That will identify the brush for you if you have never seen one before.    If the drill was operating intermittently with lots of noise and usually blue sparks coming out, loss of power, increasing intermittant operation it would almost certainly benefit from replacing the brushes.   If it is simply dead, and was ever dropped.  check the battery terminals and the trigger mechanism.  Of course inspect the battery and check inside the drill for loose or broken wires and connections. I hope this is helpful. Good luck!

Brushes over time will wear down so comparing from the old to new will not look the same. If 18V brushes fit into the your drill then it should be fine.

I have two 18v DeWalt cordless drills that I have USED A LOT -- can I replace the motor pack?


If your mechanical/electrical knowledge is up to par, then yes. I'm not sure what the cost would be..but I've taken apart a few drills and replaced brushes, lubed bearings, etc.. They are fairly simple..although I know those XRPs are tanks..you must have put it through some insane force to break it. You may want to check with the warranty on them though...my friend has gotten a few, free, replacements though the depot.

Sounds like your brushes are either damaged or the armature is failing the current. Remove the brushes first and inspect them, that is where your arcing is coming from. If the brushes appear ok, your problem is in the armature itself. Regardless of low use, if you store the unit with the battery attached, there are issues with the current draw while stored.

Hi, I have a dewalt dc925 drill. When running the


They all do that a bit. The sparks when starting up and stopping are normal. If it has been used alot brushes may be a good idea but before they need to be changed it will spark quite a bit.

It will not hurt to inspect the amount of brush material remaining.

DeWalt DW972 cordless drill has intermittent variable speed trigger. (Battery is fine, recently replaced) How can I clean the variable resistor in the trigger or must replace the whole trigger module?


have to replace whole trigger assembly.

worn brushes in the motor can also cause intermittent function, if you havent already checked those. i'd replace those first if they have never been replaced or look worn, broken, cracked, or if springs seem worn.
