Tools for drilling concrete walls?


I want to drill into my solid concrete walls in my flat so that I can fix my 17" LCD Tv onto the TV mount. I will be requiring 4 x M5*10 screws and 5 x M4*10 screws. The part of the wall where I want to insert the mount is actually the centre beam that goes all the way down through the flats, so I think there maybe a metal beam behind the wall, but not sure how far behind the wall.

What tools do I need apart from the drill?

Types of wall plugs?
Types of drill bits?

Well first off you should use a hammer drill. This will actually "hammer" while it is drilling and make it much easier to drill the holes and hammer drill bits. As for the bolts you have a couple of options. You can either predrill and use concrete screws with washers to hold the bracket on the walls or you can use expanding achors from Hilti (for example).

Also, if you are drilling into a base building structural element, I would get approval from the association before doing so. MOST likely it wont affect anything but then again thats their decisions.

As for "metal" in the wall, you will have to worry about rebar.

Put the TV on the table. Too much effort to mount it to that wall.

It can be done but if you dont have the correct tools, be prepared to rent them. With a standard drill, it will take a while to drill the holes especially if they are a decent bore size.

You could rent an SDS drill and masonry bits from HSS tool hire in Portsmouth. You will need an HSS drill bit for going through metal.
The concrete column may be steel covered with an inch or 2 of concrete for fire protection, or concrete with re bar.

Well it depends. If its a wide flange and you are drilling into the web then you will most likely have more than a couple inches to play with.

You could also try to ramset the mount to the wall. Just make sure the mount is secured well prior to putting tv on mount.

I wouldnt suggest this. Typically the holes in these mounts are 5/16" and the head of a ramset will not be big enough and you can just use a washer.

Stick with concrete screws.

Agreed, Tapcons with at least 1.25" embedment, if available. A 17" TV doesn't weigh squat.
