Thank you so much for the very helpful video. I used your suggestion to tighten up the caps for the brushes, and my Dremel came back to life! I have now ordered the brushes. Thanks again and best wishes
Thank you for this timely video! Mine was running rough, making horrible sounds at higher speeds. I have a 4000. I took it apart, thinking it might be dusty, loose parts, etc but it was amazingly clean. Almost no dust inside. Oiled the shaft, checked the carbon brushes and reassembled. The brushes do have a small furrow inside like a gentle concave dip but look fairly new otherwise. Not sure if this is the issue, but I did tighten them up a little bit to see if that helped. I will order directly from Dremel. The cheap replacements on Amazon are filled with complaints of bad fit and quality, not worth the hassle. Thank you!
Had my dremel for 20 + years and never broken down. Never changed brush . I’ll take it out tomorrow and see what it looks like and see about getting the right brush for this one. I’ve used this thing so much. Can’t believe how well it still works. I mean, I bought it in like 2001 or so. I didn’t know about the brushes until saw bought a flex shaft and others. I’ve been wondering what they are. Lol. … going to buy the 8260 cordless as I use the dremel lite so much more just because I don’t have to plug it in. Love Dremel quality. Just need a foredom next too .. :)
Thank you so much! When I took my brushes out of the Dremel, I thought the curved part of the brush was normal until I watched your video. My dremel has been losing power, just as you describe. I would have to tap it on something to get it to turn back on. Problem solved thanks to your video. Thanks again~
Oh this has answered my problem with my 4000... yes I ordered some off the internet! Bought 3 set's of them to save time in the future... they weren't the correct size or fitting! I tried emailing Dremel but had no reply as yet but I'm expecting one now the CHRISTMAS HOLIDAYS are over! Thanks for a great video.... 👍😉👍
Thanks! I appreciate what you said and your replies. Both sides did not come out easily. The person who recommended breaking up the carbon was good. I did not know how much I could mess with it!
My Dremel 4000 stopped working altogether and I couldn't figure out why. After watching this video and a couple of others, I got curious. I opened up those little caps and sure enough, the brushes are worn. I'm going to order a set and hopefully that gets me up and running again.
Bought a new 4300. Only used it for light/moderate work a few times before it stopped. I noticed that when I pressed on the brush cap on the tools underside, it would run until I let off the pressure I was putting on the cap with my finger. Next, I took a look at the brushes. The brushes looked good but I replaced both anyway with new Bosch brushes. Same thing, it didn't run unless I applied pressure with my finger. I cleaned the small silver contact located on the side of the brush chamber with a bit of alcohol on a q-tip, still no change. I even added a rubber "spacer" I cut to fit inside the cap to apply more pressure on the bush spring against the silver contact as I screwed the cap back on. No change. Still didn't run unless I applied a little pressure with my finger to the cap on the underside (the side opposite of the on/off switch) after the cap was tightly back on. Anybody have an idea of what direction to go next?
The brushes won't be making sufficient contact with the Commutator bar. The metal inside the brush holders are most probably dirty and have carbon deposits on them. So even though the brushes drop into the holders, the carbon/dirt will be preventing them from making proper contact. Eg. they are getting stuck. When you apply pressure it will be enough to push them down and make some contact with the commutator. Then when you stop pushing on the cap, one or both brushes are pushed back up into the holder again with the rotation of the motor. So look inside the brush holders to identify any black carbon deposits or dirt. Clean it off to allow the brushes to smoothly be pushed down with the spring. It only requires a small amount of carbon/dirt for this to happen. The spring is weak, so does not exert much pressure in pushing the brushes down, any small resistance is enough for them to get stuck at a certain point. Adding any spacer to the inside of the cap won't really solve the problem.
@@SCRnflz No problem.. I realise your comment was a year ago. But thought I would reply, even if it helped somebody else with the same issue. I only really know because exactly the same thing happened to me. Tbh I also tried inserting a spacer on the inside of the screw caps. It didn't work for me either. 😆 They can collect a lot of dust that gets inside the casing. So worth cleaning them out once in a while. Even a blast with some compressed air. Great tools though and thanks for your reply. 👍
I can see half of the brush is still there. Stupid question, noob here. if I wanted to wait a little longer, is it safe to pull the springs to elongate them or put a wedge behind them to build back enough pressure so it will continue working?
Done. Thank you much! This helps me actually. I had a dremel die and I'm sure the brushes are done. Now to find the right brushes and get them ordered.
My 4200 dremel appears to need new brushes as you described. However, it acts difficult to pull the old brushes out. The spring simply begins to strechntightly. Do I just stretch the truth spring until the brushes come loose?
Excellent vid and info. EXACTLY what I needed to know. I'm not a skull fan but will be starting a new hobby of using a Dremel to carve wood. Looking forward to learning from you. Sub'd.
Thank you for the video and the dremel phone number. I got right through to customer service and for around $10 shipped, got my brushes on the way. I did notice that when I pulled the springs out of my dremel that no brush came with it. So I'll have to get those out of there another way. Will keep you posted once I have time to do the "operation".
Hey Steve! Glad to hear you were able to order some. So funny thing more than a few people have told me this has happened to them with the old brush sticking in there. I will look into this more and see if there is an easy way to get it out.
@@usskullhunter I was able to get the old brushes out by taking a small flat screw driver and wiggling the pieces. All while tapping on the side. Eventually they popped out. Works like new again.
I just had the same thing happen on my old 395 Dremel... I just took a small pointed nail, place in the center, and gently hammered it to break it into pieces... the carbon is very brittle, so this is easily done... then broke the pieces up with the nail while using my shop vac to suck out all the dust and pieces... shining a flashlight into the brush chamber helps you see if it is all out or not. Had to do the same to the other side, installed new brushes (last pair I had on hand (#90030). It started up, after I turned the one brush cover that was on kind of cock-eyed... don't over tighten the brush caps!
@@usskullhunter removing a frozen brush was the main problem... glad I figured it out... and just ordered some new brushes... makes me wonder how the cordless Dremels work... my 8220 doesn't have the "brush" replacement access like the corded one... ?
Hey Amy! So I have heard this happening to others but never had it happen personally. I think you just have to use something like a knife to try and insert between the brush and dislodge it and then turn the Dremel over and lightly tap to try and get it to fall out.
My brand new dremel 4000 semms ti have non removable caps to replace brushes. The caps are little different from those in the video: can't be screwed with a flat screwdriver. What should i do in the need of replacing brushes?
Hey! Sorry for the delayed response. Ok so the best action would be to simply call Dremel up like I said in the video and telling them what you have and they can set you up with the correct brushes.
my dremal is quite new but its been cutting out, working one minute and then given up the ghost the nxt, going to change the brushes and see if that works
Try screwing in the tabs that hold the brushes in place. If the problem are the brushes this should make it run again momentarily, if not, than it's probably another issue.
Hey Sue! Sorry for the late reply. So you just have to use something thin and try and dislodge it and then turn the Dremel over and lightly tap to get it to fall out.
This video is hands, feet, and balls (...wait for it...) above the competition. I watched four “How to Repair Your Broken Dremel” before I found you. Excellent vid, bro!!! You’re calm and concise, it seemed like you knew your stuff, and had a game plan going in. You had everything in frame, weren’t stuttering and wheezing between every word, or even digressing into which stores sell the best Dremel accessories, seemingly forgetting altogether that you were making a RUclips How-To video. All jokes aside, I MOSTLY appreciate how you stated and showed your scientific method. “WHAT is the problem? Is THIS the reason for the problem? Here’s WHY it is possibly the problem. Let’s TEST. Yup, that was the problem. Dang rotary brushes just too baby. Nice!!! Oh, and hey, I get it, man. Your rotary tool just went out in the middle of you adding custom-truck-nuts to your LEGO monster-truck... ...no judgement... ...a little judgment, BUT here’s something you can do in a pinch to finish that “project” before your “parts” come in...” lol Thanks again, bro. Definite “Like and Subscribe”
Hey man! HAha well i gotta say that is the most thorough review of a video ever! I am glad I can help out in any way and it's good to hear that the video was well received :) Thanks for watching!
My Dremel 8100 was cutting out more and more, and now doesn't turn at all. But it doesn't have the easy remove caps, I'm not sure its motor has any brushes
You know, I don't have an answer for that. I looked all around and couldn't find anything about where they are. I feel like it should still have them though.
@@usskullhunter I managed to disassemble the case and it looks like my 8100 has a brushless motor. Dremel won't accept it for mail-in service because it was discontinued in 2016; instead they offered to replace it with a refurbished 8240 for $75.
Hi, do you have any advice for wobbling with the Dremel after use? I am absolutely amazed that I have looked all over the internet and yet to find a single person discussing the increasing wobble in a Dremel. There are a million discussions on when it stops working and none concerning the increasing wobble. To me it is a huge issue. Thanks
@@usskullhunter Well the entire thing starts wobbling. It is the Dremel itself because it does it regardless of the bit connected. Straight bits that would not even cause any wobble themselves do it and are really unusable. If I use a straight drill bit it wobbles so bad you can't really use it because it won't create a clean straight hole. Things like router bits that are basically straight as well are useless because the tip is all over the place. If you turn it up past 4 with something straight like a drill bit it wobbles so bad you can can see it visually create that image that looks like the bit is much larger then it is because the radius of the wobble at the tip of the bit. If I use anything like sanding bands and even place the bit as far in as it will go, it still removes all of the grit in one spot. I have to sand a few minutes, unlock the bit and slightly rotate it, lock back in place, then start again and so on every couple of minutes.
@@bzavala123 It MAY be that the Rubber mount of the rear bearing could just degrade and disintegrate, leaving the rear bearing too loose in its support... Open the halves and check for that rubber circular "cushion" that keeps the rear bearing centered and isolates its vibration. Best luck.
It is about 2 years old. It has caps where the brushes are but they are flanged and not threaded, the 2 halves have to be parted to release the caps. Probably a European modification just to annoy me.
and if you have a Dremel 400XPR like me you cant hardly find brushes for your Dremel tool, and its way more involved doing a brush replacement so good luck with that
DREMEL 3000 manual Follow these steps to check/change the rotary tool brushes: 1. With the power cord unplugged, place the tool on a clean surface. Use the tool wrench as a screwdriver to remove the brush caps in a counter-clockwise direction 2. Remove the brushes from the tool by pulling on the spring that is attached to the carbon brush. If the brush is less than 1/8" long and the end surface of the brush that contacts the commutator is rough and/or pitted, they should be replaced. Check both brushes (Figure D). Usually the brushes will not wear out simul- taneously. If one brush is worn out, replace both brushes. Make sure the brushes are installed as illustrated. The curved surface of the brush must match the curvature of the commutator. 3. After replacing brushes the tool should be run at no-load; place it on a clean surface and run it freely at FULL SPEED for 5 minutes before loading (or using) the tool. This will allow the brushes to “seat” properly and will give you more hours of life from each set of brushes. This will also extend the total life of your tool since the commutator surface will “wear” longer. BEARINGS Models 100, 200 & 3000 have double ball bearing construction. Under normal use they will not require lubrication. Part #s: 90827, 90929, 90930, My Dremel 3000 takes the 90930 which are rectangular and the slots they go into the Dremel are rectangul-ish ie the brushes can go in the wrong way because of the tolerances or gaps between the sides and the brushes. These carbon brushes (old and new) are not square blocks exactly. The side opposite the spring has a groove carved out for the Dremel motor housing which is cylindrical and remain in contact via the spring pressure. The carbon motor brushes need to be replaced a certain way or the surface area of the brush will not be ideal in fact only the tips on the far sides of the brushes would make contact - possibly not enough to allow the Dremel to spin - the brushes carry a charge and contact with the cylinder is mandatory for use. Hence the Dremel shorts out when the brush contact diminishes. Having said that it looks like the brushes can only be placed in rectangular ports of the Dremel. Knowing human nature, someones gonna force it but I guess they were always doing dumb stuff and that's nobody's fault but theirs.

It is about 2 years old. It has caps where the brushes are but they are flanged and not threaded, the 2 halves have to be parted to release the caps. Probably a European modification just to annoy me.
@@JimsonMakes ahh haha sorry about that man! Well you probably know your way around a Dremel better because of it lol
hey guy, you can export this brush cap to Brazil, the bosh in brasil changed this cap for one cap unopened!
Ah dang! Sorry to hear that Marcelo

Done! Shared the how to rust a skull with someone who may be able to help me pull it off 😍
Ah sweeet Aubrey!
Done! Thanks Hunter!
You bet, thank you Hagen!
and if you have a Dremel 400XPR like me you cant hardly find brushes for your Dremel tool, and its way more involved doing a brush replacement so good luck with that
I want to remove my brushes and just the springs came out.
Done! Ceramic skull video :D
Awesome, thanks Wynona!
DREMEL 3000 manual
Follow these steps to check/change the rotary tool brushes:
1. With the power cord unplugged, place the
tool on a clean surface. Use the tool
wrench as a screwdriver to remove the
brush caps in a counter-clockwise direction
2. Remove the brushes from the tool by
pulling on the spring that is attached to the
carbon brush. If the brush is less than 1/8"
long and the end surface of the brush that
contacts the commutator is rough and/or
pitted, they should be replaced. Check both
brushes (Figure D).
Usually the brushes will not wear out simul-
taneously. If one brush is worn out, replace
both brushes. Make sure the brushes are
installed as illustrated. The curved surface
of the brush must match the curvature of
the commutator.
3. After replacing brushes the tool should be
run at no-load; place it on a clean surface
and run it freely at FULL SPEED for 5 minutes
before loading (or using) the tool. This will
allow the brushes to “seat” properly and will
give you more hours of life from each set of
brushes. This will also extend the total life of
your tool since the commutator surface will
“wear” longer.
BEARINGS
Models 100, 200 & 3000 have double ball
bearing construction. Under normal use they
will not require lubrication.
Part #s: 90827, 90929, 90930,
My Dremel 3000 takes the 90930 which are rectangular and the slots they go into the Dremel are rectangul-ish ie the brushes can go in the wrong way because of the tolerances or gaps between the sides and the brushes. These carbon brushes (old and new) are not square blocks exactly. The side opposite the spring has a groove carved out for the Dremel motor housing which is cylindrical and remain in contact via the spring pressure. The carbon motor brushes need to be replaced a certain way or the surface area of the brush will not be ideal in fact only the tips on the far sides of the brushes would make contact - possibly not enough to allow the Dremel to spin - the brushes carry a charge and contact with the cylinder is mandatory for use. Hence the Dremel shorts out when the brush contact diminishes.
Having said that it looks like the brushes can only be placed in rectangular ports of the Dremel. Knowing human nature, someones gonna force it but I guess they were always doing dumb stuff and that's nobody's fault but theirs.
Thanks for all the info!!
