Hello!
I am looking for tips/things to consider for drilling a fairly large (30-50 mm diameter) hole through a load-bearing interior wall for pipes. The wall is made of "stone," I'm unsure about the exact material. It could be brick with plaster, not sure.
I'm planning to insert a pipe (like a VP pipe or similar) and run an antenna/HDMI cable through it.
I can't upload images here, not sure why (the "upload" button does nothing).
Therefore, here are images:

What should I think about?
Is there any risk of the wall cracking? Other risks?
Thankful for answers!
Regards, /marcus

Agree with the previous speaker's reasoning. Shouldn't be a problem at all. I myself drilled a large hole about 120mm through a stone wall and well, it's still holding 
But can't you run the cable along the wall to avoid drilling and then hide the cable behind moldings?

First drilled with a small universal drill. It was porous.
Then drilled with a cheap long drill for masonry. Could then measure how deep the wall was.
Turned out to be much thinner than I thought.
Took wires to Hornbach (where they have VP pipes up to 32 mm). Turned out that 25 mm was enough for the wires I needed to pass through.
Bought a hole saw there for brick wall and lightweight concrete (wolfcraft) 25 mm, which could drill about 63 mm deep.
Since I had a small hole right through the wall, I could drill a little from both sides, looked neat.
Sawed the VP pipe to size and placed it inside.
Turned out really well.
