Dude! This helped me fix my dads angle grinder that was given to me but turned out to be broken. I used brushes from a shop vac ac motor I had lying around just cut them with a hack saw and file now I'm using my angle grinder for the first time! Thanks so much :D
Hey Jake - I feel I learned a great deal here, I appreciate you taking the time to make a well spoken video about it! Carbon is going through a bit of a "gold rush" of late, on top of being really accessible and inexpensive. I would suggest more videos along this line, and like many of your commenters, I'm interested in making my own brushes. LOL I wish I had seen this sooner! I'm staring at a vacuum motor that I desperately need to return to service and clearly is unhappy chewing on a D cell electrode :) It's unfortunate, as battery electrodes often seem a perfect fit for the round spring tunnel of many brush holders - craic on!
Thank you so much sir. Unfortunately repairing power tools takes time and with my current job i cant do both. Anyway maybe you can cut to size the carbon to fit your vacuum motor
This is a great video - Thank you - How do I actually connect a wire into a piece of carbon? What method is used for adhesion between the copper/aluminium wire and the carbon itself?
My husky air compressor C201H needs new brushes. It has been very hard to find on the market. Them has MH907 written on. What does it mean? I found some oversized brushes, but they required file them down to set up. The material of the new ones produce to much sparks, smell and got overheat quickly. Any ideas to put to work? Thanks a lot.
Anyone know about specs for carbon brushes for vacuum cleaner motor VS for power tools? One would be much higher RPM, so is there a different makeup? I tried using brushes out of an old power tool for a vacuum cleaner motor, but they smell terrible when they get hot. What specs to look for in brushes for a high speed motor? Great video! Thanks
Do you have a place to recommend where I can buy carbon brushes? I have a Greenworks Electric chainsaw, model 20332. I have looked on line everywhere, but can't find one. The old brushes or what’s left of them measures ~ 9.1mm X 11.8mm X 15.8mm long. There is a 4” copper braided lead attached to the back. There is no spring on the brush, as a "spring clamp" attached to the motor keeps the brush pressed against the commutator. Thanks.
Hi Jake I changed the carbon brushes for new when I noticed arching and slow running of the motor.. After changing and a lot of fettling it now runs But slow and still aching the brushes are made for the motor in question ? Any tips hints thanks
Good day sir Andrew, the primary reason for arching and slow spin is that either the armature or the field coils are burnt or both. I suggest to check the armature in a growler to see if its shorted. If not, then the field coil is the problem.
Hello Sir, the carbon brush is used only to connect the armature and electricity. Unfortunately having more carbon brush will not increase the voltage. Unless you will use a higher voltage in using the power tool
Hi there are several people asking how the copper wires are held in place in the carbon brush. I have some small motors where the carbon brush is held with a spring and the wire is in its turn held with the same spring in the upper part of the holder. Conclusion you only needs to hold the copper wire with the spring and make sure it is conductive.That would work I will try to see
Yes sir it only needs to conduct electricity. Either way the holder of the carbon brush is already conductive. The copper wire is not really necessary.
I agree, but only for those little motors, whose current is not so high. For bigger motors and higher currents, the springs could become hot, and easily lost their mechanical properties. And this is why they install into carbon brushes even big copper conductors ...
nice video ..my brushes are in a hand router..they have removable caps and you jsut insert the brush..my question is i cant find exact size brushes so i was going to buy slightly bigger brushes and sand them down on some sandpaper...i need 7mm x 5.5mm and can only find 6.5mmx7.5mm brushes without special ordering them....do you think it will be ok sanding down about 1mm off each brush evenly on both sides to fit? the length is fine...i think it should be ok but maybe i wrong?..there are 2 brushes and each have a spring and copper shunt on them..very common..nothing spcecial other than the odd size.
I had to jury rig something for temporary use to get a Toro 1800 snow blower working to finish the last half of the job, so I used some solder braid and pushed it into the hole on the side, and then soldered it to the original copper braid. It was able to work well enough as a stopgap to finish the job, but I have some generic brushes on the way to replace them.
Hi jake..I have an angle grinder that has carbon brush that doesnt have a wire or spring. it is a plain carbon brush. I need to replace it and i found the same size but it has wire and spring. Can i cut the wire on the carbon brush and use it on my angle grinder?
I think my carbon brushes for my compressor are seized in the holders. One of them moves a little but I cannot remove it. The other does not move at all. My compressor sparks a lot. How can I get them out without damaging them or the commutator?
Good question looks like its a trade secret as no ones commenting.I woul d imagine its set in place of mold in loose granules and then commpressed somehow with some heat maybe
@@kkooloo5781 actually you are close. The cable is placed into a slightly larger hole drilled in the carbon and a conductive powder is tamped around it to hold cable firmly Sometimes a glue is added at the top of the hole mouth for added strength
Where can I get good brushes? I just bought a few sets for my handheld grinder from Walmart online and they literally disintegrate in 5 seconds or less. I'm more pissed off than a one legged Etheopian chasing a doughnut rolling down a hill. My work has been on hold almost a week waiting for this junk.

You're welcome sir. Unfortunately sir you cannot reattach it. It is molded together in manufacturing like a clay pot till it hardens.
Thank you. Knew nothing about carbon-brushes and their inportance. Have a good day.
You are so welcome!
thank you sir
but can tells us the best brand of carbon brushes?
its a great help. informative content.
Thank you sir 😇
Thank you, I'd never considered the differences of various sources of carbon
You're welcome Sir, thank you too for watching ☺️

Good day sir, have you tried sanding and polishing the commutator too? Rough commutator can also contribute to the sparks
Thanks
My car doesn't start after long drive. Is it the problem of carbon brush
You're welcome sir, i hope it helped 😇

Good day sir, try makita brand of carbon brushes. Proven with high quality.
Can I cut and splice the copper wire to the terminal end? My sunroof motor(brushes) are broken and I can’t remove the brushes unless I cut them off.
Yes sir you can remove it.
Do you have a place to recommend where I can buy carbon brushes? I have a Greenworks Electric chainsaw, model 20332. I have looked on line everywhere, but can't find one.

very nice info, thanks!
Thanks for the video. Can 2 pieces of carbon brushes be soldered together
Thanks sir, unfortunately no sir
@@JakeMarvinVillegas thank you for such fast response. I wonder if it can be soldered to copper plate.
You're welcome Sir, there are ways to bond carbon brushes Sir. I believe its also here in youtube
Do you k ow why all of these brushes have a California warning on them
What happens I have 2 carbon brush and I want to add 2 more to make is 4. Will it increase my voltage
Hello Sir, the carbon brush is used only to connect the armature and electricity. Unfortunately having more carbon brush will not increase the voltage. Unless you will use a higher voltage in using the power tool
@@JakeMarvinVillegas thank you for the reply. I already tried it and you are right I didn't increase voltage
Awesome info
where do you get the material for brushes, have you made brushes

The video LITERALLY says you can do that. Why would you ask a question that he already answered for you?
Is it possible to reattach the wire to the carbon brush ? Thanks
unfurtunately sir no, but it does not reduce the performance of your carbon brush as it is still conductive.
I had to jury rig something for temporary use to get a Toro 1800 snow blower working to finish the last half of the job, so I used some solder braid and pushed it into the hole on the side, and then soldered it to the original copper braid.

Thank you for valued video
My pleasure
We're do you find good brushes
On the hardware sir preferably makita brand
nice info
I live in reno Nv USA ; where can I buy good cuality carbon brushes ?
Good day sir, unfortunately I do not know of any shop in your location sir.
Quick question - If the copper wire comes out of the carbon, how to join the two once more?
Unfortunately sir there is no way to join the two again. It is put together during manufacturing.
Okay, thank you Jake.
Thank you for doing these videos. Can I ask where you can buy magnet wire and the brushes? Thanks
I usually buy from electric or hardware shop sir.
thank you for the info
Thanks didn’t know you could cut to size. Butt I have filed them. Good video
Thanks mate, it saves more money when u just cut em to size, especially if its a high quality carbon brush
Hi jake..I have an angle grinder that has carbon brush that doesnt have a wire or spring. it is a plain carbon brush. I need to replace it and i found the same size but it has wire and spring. Can i cut the wire on the carbon brush and use it on my angle grinder?
Hello Mitchell, yes you can it wont affect the performance 😇
Hmm interesting but still no information on how they work
The purpose of the Carbon brush sir is simply to let the electricity flow in the armature.
Kindly share manufacturing of carbon brushes of different grades and quality
I think my carbon brushes for my compressor are seized in the holders. One of them moves a little but I cannot remove it. The other does not move at all. My compressor sparks a lot. How can I get them out without damaging them or the commutator?
Good day sir, I recommend to disassemble the armature from its stator so you can safely remove the carbon brushes.
You sell those brushes
Good day sir, no sir 😉
Where can l find in jeddah
I'm sorry sir I am not familiar in your area
very interesting video. i'm wondering how the coper wire is held in place inside the carbon brush. anyone can help?
Good question looks like its a trade secret as no ones commenting.I woul d imagine its set in place of mold in loose granules and then commpressed somehow with some heat maybe
Yes this is most likely how they do it

Will you please let me know why flexible arm copper cut from carbon tip after 3-4 days of generator in running condition
That would probably due to vibrations sir
Dear bro 👍 nice explains 👌🇱🇰
Thanks bro
Will there be a problem if carbon brush is smaller than the original housing?
If its way to small sir that there will be wiggling there will be a problem for the commutator. It might get damage.
Carbon brushes for treadmills are extremely difficult to come by. Can anyone recommend a place where I can get these brushes?
where u from? i am in south africa
Makita brand carbon brush are really good sir
Is there any way to reattach the wire to the carbon brush
There is none sir. Think of it as clay being hardened while the copper wire is in place.
I have a problem. carbon brush is too hot and every thing around it melted what the heat 🔥 come from
Maybe from a shorted armature or field coil sir? is there sparks/arching while it runs?
Sir which carbon brush qualitie is best for a
All power tool. hard or soft ?
Should use Sir hard but not so hard that it will damage your commutator.
WHERE DO GET CARBON TO MAKE MY OWN BRUSHES
Lol tf you saying
I hope its a good quality sir
Thankyou
You’re welcome 😊
Where can we get good quality carbon brushes
I allso like to know where I can get some 17mm x 13mm x 6mm brush en eurppa
Yes sir you can sand it down
sir please which type of chemical can use to dilute the carbon
As of now i dont think there is aside from acid
How to insert wire in the carbon
There is no way to reattached it sir.
Dear friend pls help to me how to making power tool carbon brush as at small entrepreneur
I will sir, I will be uploading soon
Sir tanong lang po kya ba convert lhat ng motor na 110 to 220v
Pweding pwedi sir, increase nyu lang number of turns tapos palitan nyu ung gauge ng wire to medju mas maliit
