Thanks for posting this! I had the same problem on my 12v DCD710. Easy to disassemble and clean. I dunked the motor in some diesel fuel, rinsed with electronic cleaner and thoroughly blew it off with compressed air. Back together and working great. Easy fix and saved me buying another one!

Sparks are from the carbon debris in between the copper poles on the commutator.This creates dead shorts and slow the motor down because you must have only a PAIR of contacts getting juice at one time.If you apply power from the brushes to three or more contacts you are effectively 'braking' the motor. That's why it slows down and smokes.So,just clean in-between the poles with a slender knife ,so gently like a surgeon,or you'll make garbage of your drill.Dressing the commutator lightly won't hurt either.Make sure neither of the brushes is chipped or squared off.Also never run a DeWalt drill on bad batteries.When voltage goes down the amps go up.And so does the heat.
Thank you for your comment. I had the same problem. The dealer told me the motor was no good and that I had to by a new one. I just cleaned in-between the poles with a knife, cleaned the commutator with sand paper and replaced the brushes just in case. The drill is runing nicely without smoke. I will not run it anymore on a bad battery, thanks for the advice, makes sense. :-)
Try spraying electronic contact cleaner in the brushes while turning by hand. It will get any grease out. Your trigger sounds fine. If you have variable speed! If really keen dip motor in water and dishwashing liquid. New brushes as well when bedding brushes in.radio control motor break in method! It will have a little more power too.
I had a Dewalt DC987 and a DC988 that did exactly the same thing. After a tear down and commutator cleaning and new brushes they both continued to smoke. I thought o myself "screw this, let's have some fun" and held the triggers in on both.. Thinking that eventually they would burn up and die altogether, I was really surprised when one threw a massive spark and then started working properly. A few seconds later the other did the same. I have never had a problem since!
The same situation I had today with my Bosch PSR 10.8. A few days ago the motor starts to behave weird, sound, smoke, sparkes. I disassembled the accu. with a thought to replace the brushes but I found out that the brushes can't be reached easily. The only suggested repair that I found on the internet was a motor replacement. Then I read your post and start the same game ;). The few full speed runs seams to burned out the dirt and dust and the motor start regular run. Thanks.
My dewalt xl was dropped then makes like an old model shop smell and also cannot engage the hammer side but your opening up side to the drill is a major help. 🙏
I had exactly the same problem with my 14.4v drill. I removed the back cover and gave the rear end a good spray with Holts electrical contact cleaner, The solvent dripped out very black and was full of heavy carbon deposits. I then let it air-dry overnight and it's been fine ever since.
My Dewalt Drill started to smoke for 2 days. Without opening up the drill I could see red sparks where the brushes are. I just blasted it with compressor air where i saw the sparks. Now it is normal again without smoke or red sparks. I am glad I did not open it up, although temped to do so.
I have a DCF887 impact driver that just started smoking after I was making 1-3/4 in holes in the 4x6. I was able to make about 20 holes before smoke started coming out. Is my impact drill ruined?
My dewalts like this used to do this and brushes were stuck in holders and armature was covered in carbon and junk. A good clean and I put fresh brushes in and away she went
get a stanley knife point or use a needle to dig into them in the between armature then sand paper the armature and scratch the carbon build up between the copper slices which causes short thus you get a smell. ..the problem will be over. (simly clean the gaps between copper slices as well as sand papering them.)
I'm having teh same problem wit the exact same drill. The brushes are use so they start to sprak on the rotor. The dust on the rotor starts to fume. Just change brushes or motor iff needed ;)
My dewalt would run, smoke, then die down. I took the back off and blew compressed air in there while running wide open. It's fine now. Hopefully for a while!
This is true to some extent, but when you upgrade to battery, there is no tangled cords, extension cables, jennies, fighting for a power outlet on sight, and every time your back is turned you are plugged out, due to outlet shortage. Charge up as many batteries as you need for a days work, and every now and then look out the window as they fight over the limited outlets, in the rain, with their taped up extension leads damaged by forklifts and diggers constantly driving over them
My DeWalt cordless drill started smoking and I threw it out. I guess I could have tried fixing it, but I had it for about fifteen years. It was getting old.
I was using my impact driver on the steel roof that we are doing and it's hot up there so my dewalt driver overheated and I had to let it cool down for a while and grab another. Mind you it is like 50 degrees and we are using them for the screws non stop.
I smoked mine last summer drilling concrete. It did not smoke until nine holes and two batteries later. I let it set for an hour to cool off. Came back and motor worked about half a hole smoked and shut down for good. It smelled of burnt plastic. I figured the motor is toast.
Smoke means something is burning. If it smokes when it is switched on, it is because of dirt build-up in the motor. Just clean the commutator, brushes, and armature.
SIMPLE FIX: 1. Remove cover. 2. Remove motor assembly (easily lifts out). 3. Remove just one of the brush assemblies by prying just like in this vid. 4. Now, with wooden toothpick and Contact Cleaner spray, remove debris in the grooves around commutator (sray,scrape,spray, scrape, etc). 5. Clean also the commutator as you rotate it to get to the grooves. 6. Reassemble.
Hi there 👋 Thanks for the advice! It worked great! Yes! It was the grooves! I cleaned the commutator with sandpaper before, but ass soon as I ran the drill, it smoked and turned black again! But when I cleaned the groves with toothpick and removed tar inside, it ran without smoke and copper stay clean now! 😉 Thanks man! All Best to You! 👍🏻
Carby cleaner would work. But electronic contact cleaner is half the price of carby cleaner. In saying that if all you have is carby cleaner? Yes it will clean like new. You can use methylated spirits in a spray bottle too. Same as basically carby cleaner! Cheap!
Drilled concrete today motor only works in forward gear. Nasty smell from the battery, which was very hot for over an hour. Had the xrp for 7 years, been like a brother to me. Gutted.
Sounds like the switch is bad. Mine only works on full throttle but smokes immediately. Sometimes it will work on half throttle but temperamental. I suspect the switch and transistor soldered to the switch. I'm gonna swap with 18 volt Makita switch.cheers 👍
Typowy problem w tych Dewaltach. Należy wyczyścić komutator i udrożnić nacięcia na komutatorze bo są zalepione pyłem ze szczotek. Dodatkowo przeczyściłem szczotki. Wszystko czyściłem zwykłym break cleaninerem (odtłuszczaczem do tarcz hamulcowych). Po całym zabiegu zero objawów dymiącego silnika i zamulonych obrotów. Wymiana szczotek nie jest konieczna i sama wymiana szczotek na nowe nie pomoże pozbyć się objawów. Musi być wyczyszczony komutator i udrożnione nacięcia. (posiadam Dewalt DW988)
The Commutator on the Armature looked pretty black in the Video. After using Contact Cleaner on the Commutator to clean it and left to dry, I would have reassembled and tried it. If the problem persisted, I would replace the Motor and install a new set of Brushes to.
I have the same drill... one day I tried to use it and when I put the battery on it it make a weird noise then the battery got really hot so I remove it. since then I haven use it. any ideas what might be wrong with it?
Ana Hg well if you're in the states DeWalt how to recall of a few models you can look it up on their website something with the trigger and overheating and smoking I had the same model but mine was a DC 930 it's pretty interesting looking xrp drill
How did you make out? I wonder if the motor was the issue?. Seems to bog out and that causes the brushes to smoke?. Try contacting Dewalt online& mabe they would help. :) Luv my Milwaukee!.
If it is giving a smell I wonder if it is the windings. They have a light insulation when it melts it can give a smell and smoke. How it is melting I don't know if it were me I would take it apart and check it out.
Just pulled mine open, and the brushes were fine. I cleaned everything out, still smoked and would only turn for a few seconds at a time. The windows did have a green/white haze on one side, so I think you're right.
this method fixed my 18v xrt drill it was litterly BILLOWLING out smoke, like if i held on the trigger for 10 seconds the room would be filled with smoke and the chuck was barely turning, took it apart and cleaned the whole motor from gunk with brake clean. worked PERFECT, but unlike this hammer drill my GEARS ALL fell out and it was VERY hard to put back together. so word of caution watch the gears if you dont know what u are doing they will fall out and if you dont know how to fix shit, YOUR FUCKED. trust me this is a pretty hard fix, i would say you have to have a high skill level of fixing things if the gears fall out.
Except for the opening comments spoken directly to the camera, the rest of the video is almost unintelligible. Useful to see the disassembly process though.
It is the motor itself, on some you can replace the brushes but that doesn't seem to be the problem here, your best bet it to replace the entire motor.
Replace the motor, the armature is done... If you can take it apart completely and replace the armature, this would be another way to fix it. Alternatively you can boil the armature in oil for like 30 minutes and it may restore it, but chances are slim. I would not even bother playing with it, it is waste of time. This is old technology with NiCD batteries... not worth the effort...
I've run the shit out of my 18v DeWalt DW995 1/2" for over 25 yeas on the job as a carpenter and it has never failed me once! And it's a refurbished model.

My drill only smokes after it’s been drinking

Thanks. I used your procedure (without the cleaning fluid) and the smoke is gone. Very helpful.

You soak it in a container of thinner for a hour then let it dry for 2 hours or even overnight it cleans the motor inside motors like brandnew
This worked for me
Paint thinner ?

50° isnt that hot, bro lol

Check the armature for pitting also check brushes and make sure there is no oil or debris in the motor.
Smoke means something is burning. If it smokes when it is switched on, it is because of dirt build-up in the motor. Just clean the commutator, brushes, and armature.
You can try cleaning out the poles what the poles are touching could be its hitting up the oil or whatever liquid in there
SIMPLE FIX:
1. Remove cover.
2. Remove motor assembly (easily lifts out).
3. Remove just one of the brush assemblies by prying just like in this vid.
4. Now, with wooden toothpick and Contact Cleaner spray, remove debris in the grooves around commutator (sray,scrape,spray, scrape, etc).

worked like a charm!! I used some 600 grit paper as well.
Hi there 👋
Thanks for the advice!
It worked great!
Yes! It was the grooves! I cleaned the commutator with sandpaper before, but ass soon as I ran the drill, it smoked and turned black again! But when I cleaned the groves with toothpick and removed tar inside, it ran without smoke and copper stay clean now!

would carb cleaner work or hurt?

What did you use to clean / wash it? Sorry, I am a non english speaker so I could not understand what product you used.
Compressed air to clean dust off, then alcohol/brake cleaner to get grease of and regrease it again

Replace the motor brushes. Clean the commutator too and it should run like a dream again.

The drill is still working perfectly; as you can see in the more recent videos relating to door and window installation.
Didn't they issue a recall on this
If it is giving a smell I wonder if it is the windings. They have a light insulation when it melts it can give a smell and smoke. How it is melting I don't know if it were me I would take it apart and check it out.

it sounds like a short, but I am not a machine tool expert at all it is just a guess

Ditry armature and get new brushes if wirn to be on the safe side
I replaced the brushes and the smoke is gone.
oh i have a solution. .. put a Milwaukee motor on it. . problem solve
Same issue
Except for the opening comments spoken directly to the camera, the rest of the video is almost unintelligible. Useful to see the disassembly process though.
Change the brushes
Why didn't you use the drill gun to take the screws off......the....drill gun.....Oooooooo
It is the motor itself, on some you can replace the brushes but that doesn't seem to be the problem here, your best bet it to replace the entire motor.
I fixed mine by putting it under water
It tis a balaney stone.
Needs brushes cleaned and or replaced
what is the size of motor and kind?
Crackin' .
title says repair, i don't see any repair at all
That's what you get from American made tools. Milwaukee all the way
Always buy a corded hammer drill for heavy concrete drilling. They are cheaper anyways.
Replace the motor, the armature is done... If you can take it apart completely and replace the armature, this would be another way to fix it. Alternatively you can boil the armature in oil for like 30 minutes and it may restore it, but chances are slim. I would not even bother playing with it, it is waste of time. This is old technology with NiCD batteries... not worth the effort...
can somebody plz do did assembly of Eastwood contour tool??
can you repeat what you are saying?
My motor burnt out after 3 months of use of my DeWalt drill very disappointed never buy DeWalt again . it was smoking like a bitch
My drill sparks lol wtf
12v 18v battery
охуительно
Go get a new DeWalt brushless hammer drill xr lithium problem solved will last forever
like 200 good video(Y)
And I bet you wish you'd got the makita instead
Dewalt are better
Keelin Black Ive had them both. I believe its a 3 way tie between Makita, Milwaukee, and Dewalt..
Hitachis are probably the best.
I've run the shit out of my 18v DeWalt DW995 1/2" for over 25 yeas on the job as a carpenter and it has never failed me once! And it's a refurbished model.
Makita tools are great, but the batteries are shit!!
Same shit :)
that's one ugly drill lol
Just Another User your moms an ugly drill
