75mm is very big, there is no single drill bit that is that size

what one usually do is drill a few holes alng the 75mm diameter then punch the hole using hammer & chisel

Double brick wall is about 25cm thick?
You need to buy those very long mansory drill bit to drill many small holes in a circle then slowly chisel it out.
I dug a 150mm hole on my house wall for ventilation that way.

PS: I use rotary hammer, not just drill.

That is big hole.

Forget the bosch 550gre for such a big hole.

Even my Bosch 16re 700w bore a 100mm hole on the wood, like struggling. Hole drill freaking hot. Lastly have to use the makita rotary drill to finish up the job.

You can use concrete bore hole saw. Either diamond tip or tungsten carbide teeth. Need at least Makita rotary drill minimun requirement spec.

You need to take time to bore and not hurry. Drill and stop with plenty of water to cold down the tip.
