My wife gave me a Dremel XPR400 tool with a great deal of accesseries for Christmas last year. I was using same tool with a carbine cutting wheel to cut fin slots into 7.5 diameter phenolic tubes for my L3 project. I was almost finished when the tool got very hot and began to emit smoke from the ventilation port. I shut it down and let it cool. After a while I turned it on again. But, there was very little power and the motor sounded as if it was arcing. I checked the brushes. But, looked ok. I even cleaned them a bit and tried it again. Same thing. SO, I wrote up a letter explaining what happened and shipped it to Dremel for warranty service.
I've never had any problems with Dremel products until now. Now I'm waiting to see how the warranty department handles it. Anyone else had any problems with their Dremels?
