Discussion for the Dremel 780 (F013780000) Cordless Multi-Tool
I like the tool being cordless but I have found that is not always the best way to go. I am having a problem keeping the tool operating. In my opinion the speed control board is faulty. I think next time I will go with the corded version.
I also have had problems with the speed control board. Then the motor quit running. I got another one to replace my old one. The control board quit then the motor. I think I'll buy the corded version.
