So, the tv isn't THAT heavy, but the concrete is just not giving! I
drilled a smaller pilot hole (took 5 minutes to go 1" with a 5mm bit)
but when it came to the 8mm bit, really nothing was happening. I gave
up after about 15 minutes and 3mm having gone slightly deaf!
You can hire an SDS drill from a tool hire shop which should do the job.
Just checking - your drill wasn't in reverse was it?


Hire such a useful tool???. Haven't got a birthday coming up?, make an
excellent present to yourself!.



As an aside I don't have an SDS, but I have successfully drilled through
just about anything with a straight hammer drill.

One of the BIG secrets is making sure the drill is not going
backwards...on mine the reverse switch the opposite way to the cordless
screwdriver..and counrtless times I have had smoking drills and no
progress at all.:-)
