Dremel 3000 trobleshooting & stator repair

- Watch me rage over the realisation that Dremels are trash. I suspect the electronics to have failed in my almost new Dremel 3000, but it proves to be the stator. Apparently a common issue.

I want to say an amazing THANK YOU!!! I’m unemployed and using my dremel for all the usual stuff like grinding dogs claws, trimming bolts off saddle fittings, renovating Microsoft Trackballs and when it died it was a massive “oh shit” moment. 20 minutes with your video and I’m up and grinding again! Thank you!!
Glad to be of service.
Same here definitely saved us some money
@@FFcossag today is December 6th 2019 watch your video tonight thanks to you I'm up and running again thank you sir
Thanks for this - My 3000 also was barely used and had the same problem. Quickely Fixed.
Exact same dremel, exact same time-frame, exact same usage, exact same problem, even the exact same pin hahaha, and very easy to follow! Thanks dude!
Hi, I have an 8200 w/2 batteries. I trim my dogs nails with it every 2 weeks on a bit over 1/2 speed. It stops and the battery lights flash. The only thing that feels remotely warm is the dremel body. Batteries are charged and feel cool. What do you think may be the issue?
You are my hero!
Got the same problem and solved it with your instruction.
Thank you!! 😊
+FFcossag Thank you so much for posting this vid. Exact same problem with my barely used Dremel 3000 VS that is now up & running. Brilliant!
Bro I've been going on 3 nights of no sleep and this video is perfect
Excellent. I repaired my stator thanks to this. Great thanks. Very instructive
Glad to be of service.
What if the wire is broken from the back part of the copper winding, cant seem to unwind the wire from behind the rest so I can extend the wire to reconnect back up.
Yep, me too. Thanks for the video, knew exactly where to look, exactly what to do and I'm back up and running.
Mine is only 3 years old, but put through hell. Saved me 70$ on a replacement.
Thanks to your video I got mine working again I had the same problem but instead of adding a wire I unwrapped it a little bit back around and cut off the excess then I soldered it good video thanks for sharing this must be a known problem for these thanks to your video you save me some money
Hi quick question. My Dremel stopped working. Is there a way to pinpoint if the problem is with the brushes or something else?
Same problem, easy fix, thanks for the vid!
This exact thing seems to happen often. When you look at the little metal clip, the enamelled wire from the field winding is pressed into a little slot of metal and when the tool vibrates, it eventually shears off. Fixed mine twice in one year of light use. Dremel should address this issue.
Really appreciate your video! I'm now on my 3rd Dremel, which failed after little use and it's just out of warranty! I'll never buy another Dremel, but am going to take mine apart now to see if it's the same issue as yours ... many thanks for your helpful video!
Does anyone know if dremel carbon brush 90930-05 works for dremel 200 and 3000 ?
Your upload fixed my problem. Thanks.
Thanks dude at first all mine looked OK then I moved one a tiny bit and fall out and did trick and works again!
Hi Thanks for this video
What are the small metal connectors called? One of mine is damaged on trying to do the repair, am I able to just get one of those small connectors from somewhere?
I have no idea.
Wire had broke like yours at the clip connector but couldn’t unwind the wire and it snapped! Had to order a new Strator
How did you get the blue switch back in? I am changing the locking pin but the switch mechanism fell out and I cannot for the life of me get it back. You don't seem to have had any trouble.
Thanks, this worked and I totally agree with your opinion of the build quality.
Advisory - Don't put the bloody stickers back on, you'll be doing this again in a few months.
I have a cheapo rotary tool that has been running for ten years. I only bought the dremel because it takes a variable chuck. Wasn't worth it.
You're a funny guy. Don't know why I watched this video. My cordless Dremel 7000 is the model that crapped out on me after just 3 uses so, I was looking on CZcams for any solutions and found your video. Well, anyhow...I got a nice laugh at the beginning. Thanks.
My Dremel is in the same condition ... almost new. But, although the motor runs the shaft does NOT. Could you give me any thoughts as to how it could be fixed? THANK YOU!
Probably glue the shaft back to the rotor, lol. What an odd failure mode.
I repaired mine.... same snapped wire fault.... but now it will only run at full speed?? I agree that they are not well designed/built..... mine has been used but it's less than 2 years old......
Mine did the same yesterday on a Dremel with maybe an hour's worth of use. POS but fixable thnx to this vid.
Very clear video, I will give this a go tomorrow 🤞🤞🤞
Yup! Same problem on mine after not very much use. Also failed a second time so unwound one turn of the coil, and leaving adequate slack reconnected no worries. It seems that TOO much tension is put on the coil ends during manufacture and vibration and temperature rise during use takes care of the rest. Since fixing it a second time it worked fine until, after MUCH use, the bearings BOTH failed. Getting the rear one off - piece of cake. To get the front one off the collet shaft (tube on the armature shaft) is, so far impossible! I thought perhaps it was threaded onto the armature shaft so I tried my small c-spanner to turn it (both for LH and RH threads) - ZERO movement.
My gear puller can apply a LOT of force and it removed the rear bearing simple as, but there does NOT appear to be an easy way to remove this collet tube/shaft to allow the bearing to be removed! It's still there awaiting repair. Meantime bought another 3000 and that's been fine (so far, touch wood) and bearings are good, but they WILL go at some point and it would be nice to be able to repair the damned thing and not have to scrap it for sake of one tiddly bearing that would otherwise be a piece of cake to remove/replace.
Anyone know exactly how the collet tube/shaft is fitted? Interference fit or is it screwed to the armature shaft? Or is it one of these damned tools where the manufacturer decides in advance that any failure (ALWAYS out of warranty of course) will doom the machine? I HATE designs that are made to be assembled for production rather than disassembled and repaired in use. Do the latter, the former is a piece of cake. It's SUCH a waste.Companies' products should be internationally graded for their repairability and maintainability levels. Trouble is most (if not all) would FAIL epically!!
Wow, I have a Dremel Multipro made I think sometime in the 90's and the internals look nearly identical. It would randomly cut out, and the rpm would jump all over the place so I had to pull apart the variable switch and bend the spring contact as it wasn't making good enough contact with the carbon track. A common problem apparently. Stuff like this really makes a case for planned obsolescence or engineered to fail. They had decades to make a design bulletproof yet it still fails after an obscenely short amount of run time.
I had the same problem. A much simpler and less invasive fix is just to to unwind one turn from the stator winding and put it back in the IDC clip. Job done in 10 minutes. I think you are hard on the Dremel. Mine lasted 7 years before the failure, it was a simple repair requiring no new parts.
I need a instructional video from you
Did exactly this, worked. For future reference for anyone, find where the wire has broken, right by crimp. There won't be enough to put it back in the crimp, so unloop the wire back through the part one time, until you get back to where the wire broke, but now with more wire. Take the crimp out, pull the wire up into the v, replace the crimp, trim excess wire
thanks for the video
My Dremel also had maybe had around 1hrs total use. Brushes hardly worn.
It also stopped dead without warning in the middle of a job
I ended up grabbing my cheap $50 'Supatool' brand rotary tool that I forgot I had and carried on (I remember buying the Dremel because I can be a bit of brand snob and liked some of the accessories it came with)
Started pulling apart the Dremel the other day. Didn't get too far, didn't see anything obvious so was ready to bin it.
But watched this video now, so might have another go at it and see if mine has suffered from a similar problem
Or I might just stick with my $50 cheapo that seems to have lasted a lot longer than the far more expensive Dremel...
I'm sorry.why did you buy a Dremel if you already had a cheapo "supatool"?
because as said above, I forgot I had the Supatool rotary tool.
Thanks... I might have to be getting a new drill and you have tempted me not to go with Dremell...probably can't afford one anyway. My wee Colt has packed in because the plastic clutch joining the motor drive shaft to the drill ( why on earth wasn't it a single unit like yours ) has denatured and shattered. I've hardly used the rotten thing but have had it in the drawer for about 15 years. Guess I can't complain. I was wondering if I could pack the space with some gap filling glue..... could be good enough for the sort of tasks I'm likely to try.
My older model 395 Dremel's have never had such a problem. They must've still been built a bit more patiently back then. 2 dremel's, and a Craftsman that's the exact same tool with different stickers. I had to fix the swipe switch on and replace a bearing on another.
There was a time dremel tools were made down the road from me in Kenosha or Racine Wisconsin it's a pity that the quality control is not better
You could say it's gone south.
The fact that it didn't chooch is more a result of it going east I think.
Gone Pacific rim.
MIM. Like others made in China. Trash stuff. In Brazil we've got nothing that worths too. Foredom motors, USA made. Only thing we can rely.
It looks wire breakage at the termination point is a very common problem. The weakest point is where the wire bends into the plastic slot to be clamped into contact. The wire bend is under stress, and when the Dremel is spinning at high speed, there is constant vibration, which translates into cyclic stress at the bend. Over time, the wire breaks due to fatigue. To overcome this, I potted a little but of adhesive just before the bend to fix the wire to the wall. This will cut down vibration and therefore cyclic stress at the wire bend.
I own the same Dremel. Is that a design defect or production failure of your unit? As preventitive maintenance, do you think it is worth the effort to take it apart and bolster those clips and apply some silicone to keep those wires secure?
If you search for "Dremel 3000 problem", it seems to be a VERY common issue.
design defect, I just checked my local auction site and there are two dremels 3000 listed with this very fault (broken stator connection)
I had the same problem .It must be a fault with the 3000 as I have been using Dremels for many years.I was going to bin the 3000, but after watching your video I pulled mine apart and the fault was the same as yours.............Thanks mine is now working fine
Hi. thanks for the video. I was able to repair my Dremel. Too bad, I threw a stator some time ago. I could also have repaired it. it is the weakness of this technique of contact of the file, it is not welded, pinched by small knives, it is the place which acts like a fuse. delicate but repairable. Lionel
Thank you so much I just about had the same problem with a dremel of the same age I agree very shoddy assembly
Unwind one turn of the coil, then resolder then trim the rest.
........ Well done Mate, I have this model , my previous Dremel died of 'Rotor winding subdural thrombosis ' and I was silly enough to give them more money . P.S. Dremel impersonation was 9/10.
On my Dremel 300, the stator has a rubber pad on one side. This has to go on the opposite side to the switch lever.
thank you, thank you! very well explained
I know this is 5yrs old.
My Dremel just locked up, couldn't turn the shaft at all.
Turned out it was the impeller had moved and was jammed against the inner body.
2 minutes and we were up and running.
I have a Dremel 300 which had very little use. It smoked years ago (and didn't spin) and I have left it until today. Just checked the brushes and they're fine (about the same length as yours). Not done any further investigation. I'm only 3 min into your video so will see if it can help...
...oh, and my commutator has even less wear than yours. I can still see gold on it!
Well for me it's a different problem to yours. The wires on the stator are ok. Your rotor slipped nicely out of the stator I see. I had to force mine out and now it won't go back in without a fight.
linky that accessory kit , also what was that other tool you used at the end ?
I don't know what the kit is, on account of having bought it at Clas Ohlsson in 2012. The tool is some kind of flexy spinny thing that I got with the Dremel, it's probably not worth buying separately.
Basically, the dremel wrote "I AM TRASH" on itself.
There's been more than just a few of these incidents, all with the same problem. Mine hasn't failed yet, but before it does, I'm thinking of getting some polyimide tape and tape down the ends of the enamelled copper wire to that white insulation card. This, so that it doesn't vibrate when the motor is running. Vibration is likely causing work-hardening in the copper, then it fractures. The stator is loosely coiled which is disappointing.
I am on my second Dremel now. The first one died for no apparent reason, and I was not able to repair it. No problems with the second Dremel so far, but I think it's the same model you have.
Might be worth to pre-emptively goop that stator up.
@@FFcossag 🤔 What goop do you recommend?
What type of white insulation did you use? Special type of silicone, RTV or something?
I just used Fujik brand solid settling thermal compound.
FFcossag thanks
Don't use compressed air on anything that has bearings or is rotary. All you will do is jam up the unit. If anything vacuum the unit out. they are not trash. They just need to be well maintained. My company has 11 dremel units that are as old as the hills and they all still run fine. I don't know if Dremel has a maintenance video but they should for the people that don't understand how to maintain their tools. It isn't a hammer.
"11 dremel units that are as old as the hills", yes the old models of dremel is so good, but the new models, this case dremel 3000, is a piece of shit. I have one and sure about that!
UHM, those are "quick" connect style connectors. As they are slid into place they cut into the copper part and connect that way. just how they are.
Also, i have one of these with flex shaft connected to my 3D printer as a cnc PCB drill
That's what they're supposed to do, however Dremel did not install them correctly.
Mine had just done the same. The connectors are terrible
Exactly same problem ! Used once, put away for months and then "tried" to use again and it gave up !!! Will have an in depth look at the "piece of trash" ;=(
Same thing happened to mine after similar usage. Fixed it like you did, now it's stopped again a year later and this time it's something else. Tested everything and still can't work out where the problem is. Coils still good but no action. It just stopped. What at piece of poorly-made rubbish.
My Dremel sounds like an angry demon baby, I mean if I had to guess what that sounds like it’s my Dremel.
Good video
Time was Dremel was quality. Naturally that didn't last. Just had a 1 year old Dremel crap out. I'm not even betting. I'm sure the trash has the same issue. Definitely buying another type rotary tool next time.
I didn't extend my copper wire. Instead I just unwound one winding of the coil. Gave me enough wire to put it back in the connector :)
This guy is an idiot. That's why. You've got common sense.
I'm considering this, but don't know enough about motors and have a question: would that make the motor go out of phas, don't they need an exact amount of wraps of the copper or something..? How would it affect it?
@@ToninFightsEntropy You don't need an exact amount of windings. What Stephan Berger did was exactly what dremel expected people to do, they designed it that way. It is actually a really smart design but the video guy doesn't recognise it. Source: I am an electrical engineer.
Lol. Just came here to see if I can fix my dremel and now I've subscribed. You're funny and informative. Thanks. Although I have a different problem. The variable speed control is fucked. It's either off (0) or on full power (1--10)
Thanks, that's probably a shorted triac.
Same here. A technician I am not, but refuse to give in-FFcossag mentioned a shorter trial!?
@@FFcossag what is a triac? Cheers
thumbs up for the intro
Such a common problem with the dremel but an easy fix once you know where the problem lies. 😉
I had the same issue... about one hour of run time anddddd... dead.
i hear you bro i had my dremel 300 for a month and it died i changed brushes and cleaned it but its dead...Dremel has to learn how to make proper tools
i have the 4200 and it works very welll...
Thanks for this, I hope it will resurrect my Dremel which broke in 3 hours, two days after I took the second broken one back for a replacement - after the third broke I gave up and it got demoted to the back of a drawer. I was fairly impressed with the last one however, as it did manage almost 3 hours, the previous 2 didn't even cope for an hour.
The issue I see with them is that they simply shake themselves apart. If you try and use a 2mm drill through a 0.5mm sheet, the final hole size is almost 4mm. It makes accurate drilling not possible as you can't even centre the drill. Why they bother having a pillar mount (which I bought too) when it's this useless is completely beyond me. Waste of material, resource and consumers money.
I guess you can only use this for light finishing and cutting. Anything which requires accuracy.... forget it.
The moral of this story, don't bother with DREMEL, they are incompetent at both design and manufacture!
My locking button broke..only used the thing like 3 times...bullshit dremel...I expected better...
I've seen the same issue in another "broken dremel 3000" vid. Seems they "over engineered" it to last past the warranty period.😂 Just bought one and exchanged it for a second one because it would'nt even turn on speeds 1-3 and 4-7 had not power enough to grind a potatoe. Thinking this model is a fail for dremel. Looks nice thats all.
I was making rings and HAVE to get these orders out YESTERDAY!!!! I believe we ALL have had the same problem FFcossag. The problem is, is that Dremel is using Aluminum connectors with the copper wire in the "Stator"!! Aluminum and copper DO NOT play well together!! Mine was only bout 6 months old and in great condition! Why don't they use copper connectors?? IDK. Plus the engineering of the stator is made TO FAIL. Thanks for the info FFcossag. Every video I see where the Dremel just STOPS, it has always been the stator and faulty copper wires breaking or connectors dislodging. Fuck, for the price we pay you'd think they would design a better product!! Does anyone out there have any suggestions FOR A BETTER SIMILAR TOOL???? Thank you!!
Reason they don't use copper connectors is because they can save maybe $0.02 on each unit. But that adds up. Same thing for the brush housing. If they made that part out of something other than plastic, then I wouldn't've melted my brushes into the casing last night.
😕
It's all about saving every single stinking fragment of a penny that they can so they can sell at exorbitant prices for sky high profit.
Mine lasted three years and had the same problem
Mine lasted 7 years with extensive use. Just crapped out the other day.
Sorted my dremel......many thanks
*engrave it into the skin so it KNOWS it's trash.*
kinky.
It is better to be feared than to be loved. By your power tools, anyway.
Exactly. @@FFcossag
to be honnest, that dremel sounded like dying one even after you got it going again. Not even half the rpm it should do, and static sound pushing tru aswell.
That's because I only put it on low.
I have this problem after 2 TIMES OF USING IT!!!!! Dremel gave me a lifetime warranty with a lot of small letters i actually skipped them and repaired it myself since i can't wait everytime this thing blows.... I bought a dremel bc it seemed to be a Quality tool... What was i wrong!!
Same problem with mine. Disgusted. The second one I have bought! Stupid me!!
gracias por vídeo, pero te faltó una cosa por hacer, en tu vídeo se ve que las delgas están negras del desgaste de las escobillas, para una reparación al 100% habría que lijar las delgas y dejarlas de color cobre en lugar de negras que las dejaste.
In English :
thanks for video, but you missed something to do, in your video you see that the delgas are black from the brushes, for a 100% repair would have to sand the delgas and leave them copper color instead of black that the you left
It's perfectly normal for brushes to leave black marks. Graphite lubricates the commutator and makes it last longer.
am i the only one seeing this: right after the "taking apart" the dremel, the blue wire was on the right side, once he assembles the dremel again the blue wire is left?
Doesn't matter because it's alternating current. If it was direct current it would matter but only to the point that the rotation would be reversed. However, unless one is quite observant & very particular, they might not even notice.
But again, with AC current, the rotation will remain unchanged regardless of how which wire is connected to which input.
After having written all of that, a very easy example of why it doesn't matter just came to mind. Assuming you're in the USA, many electrically powered devices now come standard with the plugs on their power cords made to fit only one way into wall receptacles. You know, one blade is wider than the other...
Well, it used to be that this wasn't the case & that's because single or "split" phase AC current works irrespective of polarity.
The idea behind the blade size difference is so that the neutral connection from the device will end up connected to the neutral side of the receptacle & the hot to the hot.
Still, in the grand scheme of things it doesn't matter because if an untrained or lazy person wired the wall receptacle you're using "backwards", then you're in essence, swapping the blue wire with the white at the source (receptacle) rather than at the connection point in the video when you plug it in.
I hope this makes sense but if not, I'll try giving a different example.
👌🏻
Good video, Yr right these aren't ay better than the one's you can get for 20 quid. I got a used Clarke of eBay for £6.50 hardly used and defo as good as the Dremel.
I have a 20 years old cheap B&Q multitool that is in constant use, excellent low speed control, and rock solid reliable. My Dremel is way too fast, and blew that wire after an hours intermittent low speed use. Never again will I buy one of these.
for the first 5 seconds i thought its actually working until i noticed there is no debris flying to buttFuckEverywhere ......
This has happened to me too. Dremel quality is VERY low. Junk, basically. You are better off search ebay for "rotary tool" and buying the cheapest no-name brand unit.
I've had enough of this expensive brand bollocks. Damned if you do, damned if buy cheap. My latest Dremel is a Lidl. Let's see what happens. Cheers, Ian, Birmingham UK
Good luck. Lidl products tend to be pretty decent.
Lol - mine was from Aldi - it has lasted longer than my dremel
I have the ALDI one too. Probably made in the same factory as this and just rebranded.
kafkaian 8
Ah my copper wire is too far apart to resolder 🤬
Same here. Had it for two years....finally had a project....then it died half way through first project. Unreal. Not happy with Dremel.
I hate when you try to do a 5 min job and it ends up being 10x longer because you have to repair something. I kind-of expect it with cheap stuff, even though that still annoys me, but for expensive stuff I would have got as annoyed as you.
SidneyCritic ComedyHound exactly what’s just happened to me 🤬
Same issue on mine. Piece of junk not worth my time to fix it.
Shame you didn't show us how you fixed it!!
Mine hadnt even dust in it, it just died.
Yes they are my friend any company that releases a piece like a dremal should be closed . They make money in replacement not fixing.
I had 4 Dremel's the last 2 years. They all crashed. Dremel is crap. I will buy something else this time.
I used mine twice before it quit. Not made well at all.
LOL, funny!
my clips also failed after being used 5 times,..in all,about an hour of runtime,
I have had a Dremal hand tool and used it for 20 years with no problems every day. The problem is in modern teaching. The engineers are colleges are turning out have no real training in the knowledge in, or of the reliability of the materials they are designing in the products they hope to make. Any tool made of plastic is made for a short life. Plastic , (all kinds) is garbage. If they were educated right they would know this and maybe we could bring back the quality this country once was noted for. To make my point.... My Ford Model "A" 90 years old car, still can be fixed and is still running. Put that in your pipe and smoke it. Nothing made today with plastic will last 10 years You can make book on that.
Any tool that isn't used often still needs to be maintained. I have had Dremels for decades that still work well.
You have become a dremel lol :-D
I have a very cheap version of that dremel, it has effectively a lighting dimmer circuit for the speed, triac/diac some caps and resistors, and a bridge rectifier to drive the motor with d.c.
Works very well really, but even with the speed set to lowest its still a bit too fast.
Your dremel wasnt assembled correctly, blame whoever taught the assemblers.
If i was to buy one i would fully agree with you, but the cheap one i have was a present, that was 6 years ago and its still working :-).
I thought he did an excellent impression of a dremel :-D
I'm blaming Dremel corporate for not speccing a decent support for the winding wires. Silicon would have made this a non-issue.
Yes that would have been better.
The motor itself looks good enough for the task.
Do you often do impressions of power tools lol :-D
hey if anyone you know has a model **Micro 8050** they should check this recall list out

I have had 2 of these dremels in the space of 12 months ..it is always the same issue snapped coil the clips are a pain in the ass to get out the last one i fixed the end of the coil that snapped was from the start of the coil so couldn't be unwound i had to strip a piece of computer wire to get a length of copper wire from it to solder onto the the snapped coil absolute nightmare
Mexicans do a half ass job assembling these dremels
Thanks for tip. Mine stopped working too , and exact same problem. One very thin copper wire just hanging there. Not going to bother fixing it. It's going straight into the recycle. DON'T BUY DREMEL !!
That seems a bit wasteful.
Have to agree with the complete utter piece of shit and trash part..my button wore out after 2 or 3 uses..about 5 minutes each..now the crap won't even turn on...F--- Dremel..good video though :)

My Dremel 3000 is just 3 years old and have come to a final stop, even though three years it is hardly ever used
Not to impressed
Go Proxxon. A lot better
Gary Price Agreed! I've followed the advice I read somewhere: use a Proxxon machine with Dremel bits. I've got a Proxon IBS/E and it's awesome. Wanna get the MB 200 drill press stand for it.
Oh really? Thanks. Was googling tools that are better than dremel but they didn't come up. Just been on their website. Seem like an ACTUAL tool company rather than dremel.
It's like they give a shit about precision
