I Have 2 Faulty Dremel 3000s. Can We Repair Them?

- I bought a Dremel 3000 which worked fine for a while and then stopped working in the middle of a job. To get the job finished I went out and bought another - but now there is a problem with that.
Can we repair both of them or at least make one good one out of the two? Let’s see. NOTE: Please watch the whole video before pealing the stickers off the Dremel case. - วิทยาศาสตร์และเทคโนโลยี
Brilliant guide - I had exactly the same issue just now and you gave me the confidence to investigate and fix it ...... that means another piece of electrical equipment which won't have to go to the dump !!
Thanks a lot :o)
Well done. I've had quite a few comments from people who've had the same fault. Better design and manufacture would help to keep things out of the dump too!
I stumbled across this minutes before putting my Dremel in the skip. I am so glad I did ,, you have saved me buying a new one... Brilliant thanks 👍
Nice to know I helped save something from landfill.
Thank you so much for helping me fix my dremel. I have only had it for a week and just bought some new tips online when mine went dead on me. I decided to follow what you did and it was exactly the same problem. I fixed it!
Glad you found it helpful. I'm planning to make another Dremel video before too long so look out for that.
Thanks so much for posting this detailed video - I had the same issue with a detached piece of wire and fixed it as you showed by soldering some more wire to make the connection again. Delighted 😊
Good to hear. You'll be pleased to know that mine is still running.
Thanks for helping me fix my dremel, I had the same problem with the copper wire that you had.
I uncoiled it a bit to have some slack rather than adding a piece to it, but the dremel works fine again now :) I only regret now watching the entire vid before taking off the stickers, would have cut them in half like you did on the 2nd one if I had known ;)
I've updated the description so hopefully, in future, people won't peal them off like you and I did.
Thank you so much this will help me a lot in trying to fix mine.
Glad it helped
Very helpful, I will attempt to figure why mine quit! Thanks and stay safe.
Good luck. I hope you manage to repair it.
Excellent video. Just fixed mine, same thing happened. Many Thanks
Thanks for the comment. Sadly, mine has failed again so I am going to be doing another video on it soon.
Thanks for sharing the video. I had exactly this same issue in my Dremel 3000 and have seen hundreds of Dremels in the internet with this issue of broken wire. It seems to be a design issue.
Yes, it does seem to be a design issue. I've had many, many, comments to this video from people with the same problem.
Brilliant video, thank you.
Alex, Cape Town.
Glad you found it useful.
Thankyou! Same problem mine had.
(purchased brand new on Sunday, arrived yesterday!)
Glad you found it helpful.
Goodnight! Thanks for sharing your knowledge. It helped me to solve my problem.🇧🇷
Glad to have been able to help you.
Thanks for this, I had exactly the same issue as your first one "ded", soldered up a tiny piece of copper wire and got my 24ohms. 😁
It seems to be a common problem on these Dremels.
I had exactly the same problem- my trusty Dremel 300 suddenly stopped working when I was in the middle of a job, & I immediately rushed out & got a Dremel 4000 to finish it! Then later when I'd calmed down a bit, I took my 300 apart & traced the fault to a bad connection in one of the field coils. Then it developed a problem with the variable speed switch, so it needed one of those as well... So now, I've spent money buying a second Dremel plus the parts to fix the old one... Oh well, I don't mind, as I do love my Dremels. I did at least get some extra accessories when I bought the second one- so then I had to go out & buy a bigger tool box for the extra Dremel & its accessories!! 😝
I've had quite a few comments on this video from people who were, shall we say, rather disappointed with their Dremels so it's nice to hear from a fan. I did buy Demel on their reputation as a quality product and was disappointed to have has as much trouble as I have with them.
Still, I've not heard anyone recommend anything superior and they're certainly better than the cheap alternatives.
You can use a hair drier to heat the label glue to remove it. Button would still work. I would get a keyless chuck & get rid of the collet system. All my Dremels have a keyless chuck installed. My oldest Dremel is from 1981, I own 4 - 3 wall plug & 1 battery. In fact after my father tried one, I had to hide the rest. He kept taking them. I'm a model railroader so on some projects I have a couple of Dremels set up for certain repetitive tasks so not to change bits back & forth, just grab the tool set up needed.
Great idea about softening the label glue with a hair dryer - I'll remember that.
Using a keyless chuck sounds like a good idea. I use their "SpeedClic" system for little cutting disks which wear out quickly and that seems to work OK.
thanks! i repaired my dremel doing the continuity test. the enamel wirings ends seems to break easily if the the motor got stuck. unfortunaly i had to solder those wires directly to the metal connector. we have to watch out to not let solder into those 4 connectors cavities, if so, the head piece won't fit correctly.
I guess they're like most things these days - not really designed to be repaired.
It's always good to check ourselves tools when they stop working, sometimes we are able to fix them and save some money instead taking that tool to the technician 😊😊. About Dremel number 2, you can make a drill on the metal button, and put a screw in it, give shape to screw's head with a file so it fits into shaft's holes. This way moto tool ends almost like brand made, and tools can be changed as it's meant tio be. Well, that's what I thought to fix it and leave it as original as it can be.
Sounds like a great idea. I'll try it sometime - perhaps make a 2nd little Dremel video.
Interesting video and channel content!
Thanks. Glad you found it useful.
I also have two, a 300 & a 4000. The 300 id my favourite!
Glad to hear you like yours. From the comments I've had quite a lot of people aren't too impressed with them.
@@TripplikitElectronics I can't imagine why, it's lightweight & powerful with a good range of speeds. On the down side, they do go wrong perhaps more than most. I have had at least 2 faults with mine, like a cut field coil connection & faulty speed control.
Put the multichuck from the fully working one on the other one with the faulty locking button?
I actually use the one with the faulty locking button for mini cutting wheels which is what I use the Dremel most for (cutting off small screws etc). I use the other one for all the other odd tasks where the Dremel is useful.
Could you possibly drill through the shaft to make tightening and loosening better ?
This might be quite difficult to do - I suspect the shaft will be hardened.
This is the second video showing the same problem as the Dremel 3000, it happened to me exactly the same. Thanks for your instructions. But is it possible that the exact same problem happens in three cases and maybe also to others ?!
I guess if one fails in a certain way it could be a weakness in the design so many of them will fail like that.
i bought mine in juli hardly used it because of corona now i got 2 jabs there deciding to have a lockdown i got the mini router not a proper router but i think i must of pressed the button on chuck by mistake and now the chuck wont come undone my friend has a 800 battery model he use cable crimpers to unlock it i ordered two new springs with bolt but your idea better probaly to drill a new hole in it then push a nail threw it would be a idea
I still haven't got round to doing another Dremel video and trying this idea out - must make it a priority.
I think you can get a small chuck to fit a Dremel. Ideal for one with the shaft locking pin failure. Alternatively make a short pin tool that’s easy to hold against the tool in the palm of your hand. Thanks for the really useful video. 👍
PS, use some nail varnish to lacquer the bare wire. You can buy enamelled wire of course. An insulation check would be a good idea after that sort of work.
Since you mention it I might have a small chuck for a Dremel somewhere - I'll have to look for it. Not sure how reliable nail varnish would be as an insulator in applications like a high speed motor where it is subject to vibration and high acceleration.
Yes, I agree I should have done an insulation test - I'll do it the next time I use the Dremels.
I was given the same model to repair. The same fault was discovered. I didn't extend the wire, but simply...well 'almost' simply...unravelled one loop that left me with enough to terminate it with the press in connector.
I guess this problem is fracture caused by vibration of the core. I added a couple drops of cyano to the wire, and the same for the other three.
This does seem to be quite a common problem which probably does result from vibration. Un-looping one turn of wire, as you have done, will affect the performance of the motor but probably not enough to notice. The second repair on mine is still holding up.
great video a multi metre would be handy time to learn
RATHER THAN JUST REPLACE PARTS to use one THANKS FOR SHARING
Thanks for the comment.
The Armature and Stator of Dremel Model 395 and Dremel 3000 the same size? it is possible can fit this armature and stator into Dremel 395? thank you.
Sorry I don't know the 395 so I can't really help you.
drill a small hole through the shaft leave the button and retainer out then put back together and use a rod to run thru the shaft to lock the shaft.
That's what I ended up doing. I used a drill bit with tape wrapped round it as a "rod".
I have a 3000 model, and have this strange problem. Last week ran great, i did some work with it, and today, i wanted to cut something with it. It worked like a minute, than it started going really slow. If i trey higher speed, it will go a bit faster with each speed, but still going slow and it’s impossible to cut anything. I tryed the brushes first, but they seem fine. Any idea on what might be wrong ?
There's not a lot to them really. If it's not the brushes, is there a problem with one of the bearings? Is something catching against the armature? You should be able to spot either of these because it'll make a graunching noise when running. Also when you turn it by hand you'll feel some resistance.
If it's spinning freely I would suspect a problem with the controller electronics but I've never had reason to look into the electronics.
@@TripplikitElectronics no resistence, spinning by hand is normal, no out of the ordinary sounds as well, i took it apart, bearings are intact
As I can't solder. Could I just uncoil some wire and feed it through?
That should work. Worth a try if you're not into soldering. I'm really used to soldering so that was my first option.
@@TripplikitElectronics Please tell me why you say different things, here is what you said above this comment... Un-looping one turn of wire, as you have done, will affect the performance of the motor but probably not enough to notice
At least you didn't have the hated 4200 model, with the quick change chuck that NEVER worked. The 3000 is the update of my 395VX. That stator winding must have been nicked during assembly and broke due to vibration. That shaft lock, looks like an interference fit on the main shaft, rather than all one piece. Wonder if that can be replaced.
I did look at obtaining parts and I could find the whole shaft assembly for sale but not the shaft lock. As an interference fit I imagine it would not be easy to get off and on. I agree with you on the reason for failure - just a shame the can't be assembled with a bit more care.
@@TripplikitElectronics After watching a couple of videos on the stator winding problem, it all breaks the same way. I have the 4000 as well as the 395VX. As a preventative measure, I have decided to take them apart and put polyimide tape along the wire so that is does not vibrate when the motor is running. Thinking about it a bit more, work hardening is probably the cause of the wire becoming brittle, then snapping, rather than assembly damage.
@@TripplikitElectronics An you're right, it is sloppy production quality by Dremel.
Has anyone noticed that the speed/power switch is slightly erratic at lower speeds (between 2 & 4)? Mine occasionally won't even start spinning. I have to go back to "power off" and again to 2. Also, once the selector is at 2, the speed seems to change on its own over time. Not by a lot, nevertheless, it's inconsistent, and it keeps increasing on its own. It's my second Dremel. I sent the first one back for exactly that reason. Is that anyone else's experience? Thanks
To be honest I'm a bit of a hooligan and always use mine at maximum speed. It sounds like the speed control is some kind of a potentiometer with a bad contact. Maybe try squirting some contact cleaner into the switch / speed control.
If I have either of mine apart again I'll have a look at how the controller works - just out of interest.
dremel didnt think about quality when producing it
I've had the 3000 and it died on me while it was still new, Dremel makes sluppy job manufacturing those stators.
Going by the comments I've had on this video, it seems that they do.
Well the rotary multi-tool from Dremel it's expensive and furthermore, it's
single use I have also a rotary multi-tool but from Skil and I have no problems with that tool until now!
I thought Dremel was the best available but perhaps that is just good marketing on their part. Maybe it is time I looked into alternatives and treated myself to a new one.
The plastic nose cap went lose ( thread) . Is ther any way i can fix it please?
I presume you mean the grey thing that screws on to the business end. As I recall, I took mine off at some point and never bothered putting it back on.
@@TripplikitElectronics do you suggest i just break that part in two ( slice ) so i can put other accesories like the router guide ? Thats what i have ( desperately) in mind
Thread went loose, and i cant remove /unscrew it.
@@TripplikitElectronics same here. It's useless, and I can see the drill / screw tip better without it
Dremel supply the collet locking ring and pin as a spare part for about £5
The problem isn't the pin but the hole in the shaft getting egged out. I would have to replace the whole armature / shaft assembly which is expensive.
Find a drill bit that will fit in the hole in the shaft.. less chance of slipping out of the hole.
Yes. That's what I did in the end.
I had a 4000, minimal use, it just stopped working, my pal has one he said he's used it twice, tops, I used it maybe 3 or 4 times and that's stopped too.... Now I see theres Stacks of people who's dremels just stop working..... I bet an Aldi Special would of lasted longer.... Bad tool... Bad company !
Sad to say I think you're right. I bought the Dremel because they were the original and I imagined they were producing a quality product to protect their name. It seems not. I think next time Aldi have them in, I'll grab one and see how it matches up.
This English demo is a breath of fresh air those Americans need to watch and learn how to educate properly. Stop rabbiting on and show us what to do as in demonstrating and less chit chat and defo NO ROCK MUSIC
Couldn’t agree more Jack. Could have done with some potters wheel music for the rebuild though!
"dead" 🤣
Put it on a flexi shaft problem solved
Thanks for reminding me. I keep meaning to get one of those.
Punch that rod, my machine has the same problem as you, and I punctured the rod
I'm planning another Dremel video so I'm going to have a go at doing what you suggest.
Need to check the brushes first
Since they'd had so little use, I assumed the brushes were OK. I guess if I hadn't found any other fault I would have looked into the brushes.
i won,t buy another one.
I don't think I will either!
awful, losing the will to live
These are garbage, terrible design/build quality, buy a different make
I wouldn't say they were terrible compared to say a £15 unbranded one of eBay. However, I have been pretty disappointed in the quality of a product that is supposed to be the market leader.
