Hi.
Whilst working in my own garage I was drilling a hole in the exposed brick wall joint. Solid construction bare brick, 1920s, no plaster.
About 50mm into the brick joint there is a fairly loud bang and a flash which I think came from the bit end - which is now bright gold colour, but not burned or with missing chunks. The drill is a 6yr old infrequently used Bosch SDS and a rusty long (700mm) 10mm drill. It took out the 20A circuit breaker but not the RCD or the 10A plug fuse. I know there are no cables or metalwork in the wall, but the wall is damp as the drill 'dust' was gooey and steaming and the drill was finding it heavy going. I reset the MCB and was unable to see anything remotely significant so I continued drilling with no further incident.
Should I be worried? What could have caused this?
Thanks.
