[Shop-talk] Dead Dremel -- suggestions?

[Matt Trebelhorn]

Any suggestions on repairing a year-old dremel that suddently started  
billowing smoke and died?

400 Series XPR, I think.

Brushes look okay.

Haven't opened up the case yet -- didn't have my TORX drivers handy.

Rotating bits spin but feel a little 'notchy,' if that makes sense.

I was using the cut-off wheel to cut out a broken stud, white smoke  
started pouring out the front of the tool.  I shut it off -- it was  
still operating -- and now it's dead.
