Has your Dremel 3000 / 395 stopped working? New brushes not fixed it? Let’s have a look inside and find an inherent design flaw, and make it better than new :)
This was the problem with my 3000 as well, thanks for this video. I originally thought it was the broken armature winding connection being shown in several videos here on RUclips because when I banged in on the side it would work briefly. Also, if I put a clamp across either side of it to apply some pressure it would work. But those connections were good and there was continuity through both windings. So after coming across your video I took it back apart and started looking at the spade/lug terminals between the switch housing and the stator housing. Sure enough, they also showed signs of arcing, and on one of them the receptacle was very loose, one half of it was a bit bent and deformed and it was quite dark from arcing. In my case I was able to take a micro sized jewellers screwdriver and bend the deformed half of that receptacle into a position that tightened up the connection and it works fine for now. BTW... while mine is about 6 years old, it has been used very lightly and infrequently and has never been used for the the type of stuff you used it for. I therefore think that your heavy use was not the problem, it's a design flaw. The heavy use would surely cause the failure to occur sooner though for all the reasons you mention.
Nice fix! You were definitely asking a bit much of that poor little Dremel tool by grinding on lug nuts with it for three hours, I'm not surprised it started protesting.

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.
