Drilling a c. 15mm hole in a supporting wall 'should' be ok right? I mean, you drill holes for pipes etc. much larger than that in external walls. Will line with conduit.

Just planning out where all the electronics run in the lounge renovation, so it will hopefully be a lot neater than current. I can't figure out a better way of getting a HDMI cable from one side to the other. Concrete floors so can't go under.

You are going to use ascending diameter drill bits, yeah?
6,8,10,12, 15mm for example.

Your drill will thank you,
and if you have to use the Hammer function,
you'll do less damage to the wall.

I probably wouldn't have thought it, so cheers for that.

If you are pilot drilling like that you should use bigger steps up. Too small change in diameter with a masonry bit you run the risk of the bit catching and being very difficult to remove.
