Question about Dremel Tools & Hardware - Others
I was using a brand new dremel 4200 with a diamond circular saw attachment and it quit after 5 minutes after cutting about 4 inches of floor tile. The blade seemed to go through the tile easily enough and it did occasionally slow down if you applied too much pressure but i was careful about that. I was hoping maybe it overheated and had circuitry to automatically shut it down but it is not starting up again. So either it is defective or maybe i did something wrong but if that is the case I would say the design is flawed if it breaks that easily. I had dremel tools years ago that never quit like this.

No.. the issue issue is the switch inside. when your Dremel 4200 stop working, press firmly the grey area between the speed selector and the brush housing. I think this a defect in the design of the 4200.

The earlier 4200's seem to have a lot of stuck brush problems but I think they changed the housing material to at least make that less likely. If you find that one of the brushes will not come out easily, it is most likely the stuck brush problem. The tool is hard to disassemble but you can do that and clean out the brush holders. I think the problem is actually too much clearance and the brush dust causes the brush to stick. I cleaned out mine and was able to put some copper tape on two sides of the brush holder and the brushes still fit. However copper tape is not something most people have lying around.
There have also been a lot of reports of switch problems. If the brushes slide in and out easily, you probably have the switch problem.
Complain to Dremel even if your 4200 is out of warranty. They do want to make their customers happy and the 4200 is not doing that.

I have had my dremel 4200 just since Christmas 2014 (today is 07/23/15). It quit during a normal small project. Read online it might be brushes, though didn't think it should be that so soon as I am a VERY casual user. The brushes look like they are melted in there. Had to yank on the brush and it came out with nothing attached. Bought new ones but they don't seem to fit as if something is still in there. Anyway to know? Any way to clean it out?

SOURCE: Dremel motor dead.
absolutely astounding! Had my Dremmel for 10 years and abuse it and use it it has been wet and its out in the shed. Never had a days trouble.
Now when it was in the case was the case shut? My thoughts are mice piddle which if it gets inside will corrode everything. I say this because a bigger drill of mine got damaged in that way. No external signs of damage but when opened the damage was there and it could also be then smelled.
My only other thoughts on this is to get you to check the plug to see a wire has not pulled off, after that I would suspect the dremmel switch has a fault.
all shots in the dark! but have to start somewhere when you are riding blind.
Thanks for using FIXYA

Testimonial: "Great suggestions for a range of starters on troubleshooting this (would never have come up w\mouse turds!). Thank you!!"
it is the coupling inside of it called a flex coupling and it seem s like it is made of wax or something. tomorrow i will go to home depot to see if they carry metal ones that won't break.

Something amazing just happened! On my monitor screen, window popped up that said, "ASK A QUESTION - LET OUR EXPERTS SOLVE YOUR PROBLEM FOR FREE".
I couldn't resist getting expert advice for free, so I clicked on the window. I was immediately taken to a magical world where I can pay for expert advice. I opted not to pay for expert advice. The next day, I was asked if the help I received was helpful. So here I am posting this response. I haven't received any expert advice yet, but when I do....!

You can go to any repair facility and buy a replacement cord making sure of the wire guage and conductor (2 or 3) what you can do is make a wiring diagram and remove the old cord and holding the cord about 10 inches from end pull one wire at a time and if there is a break it will pull out to confirm your suspicion. Let me know if you need any more help and if I have answered your request would you please rate this response accordingly and thank you.

hello. You loosen the arbor at the base of the shaft closest to the tool. There is a tiny wrench in the kit that came with the dremel, or you can use a pair of pliers to loosen it. Joe
