Trying to help a friend with a sprained neck mount a 14" tv on a bracket in
a 70's flat with internal concrete walls using a standard hammer drill
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!

Do I: Drive all the way to B&Q and see if there is some super drill bit for
ridiculously tough concrete (is there?) , OR, use a good splurge of "no
nails" to glue a square of wood into the wall, and then drill into that?

Only problem with that would be how she removes said square of wood when
bracket isn't needed or when she moves out and the landlord comes to not
paying the deposit...


Neither. Invest in an SDS drill - either Bosch or DeWalt (cost
£80-90). This will allow you to drill into the concrete like butter.
However, do make sure that you give the impression to the lady that it
is taking considerable effort so that she will think that you are a
real he-man. Hopefully, she will be very grateful.

No-More-Nails is not safely adequate for a job like this.
