No, I got the rotary tool from the US. I contacted the B&D India also but they said they couldn't help me (might be because I didn't buy it here in India) and should get in touch with B&D US instead.What?
Did you get in touch with B&D US by mistake. For any repair you will probably have to go to a local B&D repair centre. That's what I had to do to get my Bosch sander repaired when it had shorted like yours' probably has. In your case, it might probably be just the carbon brushes needing change.
What do you suggest? And how much did it cost you to get it repaired?
