Passing a Cat5 cable through a wall.

[EyepodI]

Ok this should be an easy 5 minute job but it is vexing me. I've done this before for a friend with a coax cable and simply drilled from one side of the wall straight through to the other. Job done, simple.

My wall is a dry wall type (I think that's what you call it). Stud work with plaster board screwed on it. Same as the friends wall but it seems way way thicker - same builders though. Now when I tried to drill through the wall the drill bit was not long enough so didn't pass all the way through. So went to the other side of wall, measured up same point drilled that side. Intention was to pass coat hanger wire through both holes and tie the cat5 cable onto coat hanger and pull it through.

Now the thing that is baffling me is that looking at the thickness of the wall where it extends into another room it only appears to be about 40cm thick. But I am poking through over 50cm of coat hanger and still not meeting with the other hole. Coat hanger is hitting something springy in there, not sure what it is (membrane or insulation - not sure). The gap seems Tardis like

Can you even buy a drill bit diameter slightly wider than a cat5 cable and going on for 60cm in length?

I am a bit of a DIY noob but....Frustrated

The wall will be filled with insulation.

You can buy drill bits which are long, i guess if you really cannot locate the hole on the other side, use a bit similar to below, once through, release the bit, tape the cable to the bit, and pull the bit through the wall.

Thanks for replies. I think I will have to get one of those. Saves messing about.
