Drilling into old VERY hard concrete - or give up and use "no nails"?
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... |

Just get yourself a SDS drill and marvel how easy it will make this job. Last year I renovated my parents old house and I remember him when he used a thump and turn chisel type bit when he tried to put anything else up when I were a lad, and in later years burning out and blunting drills etc. However with the Makita SDS it was so easy I just couldn't believe it and really it was a pleasure doing hole drilling after that!....

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. -- ..andy |

It happens that Jonathan formulated :
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? You need to look up an SDS drill and bit. Expensive for a single use though, but it is the only way. 'No Nails' will certainly _not_ support that kind of weight - fine for holding the wood batten alone, but not for anything attached to the batten. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

I wouldn't rely on glue to hold a TV bracket. As other posters have said an SDS drill will go through concrete with ease. However an ordinary hammer drill shouldn't struggle that much. Are you sure you are not drilling rebar? If you are, stop before you do structural damage. Move the hole a bit and try again. |

You might try a steel drill but be prepared to throw that away. But it will be cheaper than buying an SDS then finding you still have the problem. Where exactly is the concrete? |

Of course, that's a really bad thing to do in a lintel, where you often have only a single rebar anyway. Time for you to take your tablets, take a deep swallow of water, then a deep breath, make yourself comfortable, get yourself properly composed and mentally balanced then read the ****ing thread you dimwit. Then, who knows, you may find yourself ready to come to terms with the fact that a pneumatic hammer pushing a revolving masonry bit will not cut its way through anything. The reason they revolve is so that they can sweep away the massive quantities of dust they make pulverising the silicon crystals they are designed to punch through. |

SDS stands for the initial letters in German of (something like) Insert, Twist, Lock. It was invented by Bosch and refers to a method of fixing a drill bit or blade. The letters don't have anything to do with pnumatic hammers although we use them that way. -- Dave The Medway Handyman www.medwayhandyman.co.uk 01634 717930 07850 597257 |

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.:-) |
