We have bought outdoor lighting (Philips hue Turaco) for our house. Time to replace the ugly 70s lamps. There are a total of 8 lamps with two holes each to be mounted on a brick wall. What kind of drill bit and anchors should I use to prevent the brick from cracking and to ensure the lamps are securely fastened?
5.5 mm carbide drill bit that runs a little slowly and not with hammer and full speed, then it turns blue. Then red plugs and maybe stainless steel screws, so there won't be rust streaks on the facade. Assuming that pipes with cables come out that should go into the back of the fixture.
I have a different opinion. I usually use a hammer drill with medium-low speeds and then let the drill have a chance to cool after perhaps halfway through the hole.
6 mm concrete drill, 6 mm plug (the color doesn't matter but brand-name nylon plug) and 4-4.5 mm stainless steel screws.

I also say hammer drill but definitely not rotary hammer, as the brick would crack. For me, it has worked best with an 18 V cordless drill with hammer function, i.e., moderately weak one. 5.5 mm drill bit and regular red plugs. Stainless steel screws outdoors.
Have started using a drill with 4 cutting edges at the tip. Often there are only two, and I find it wobbles and strikes, making the hole uneven and slightly too large. But with 4 cutting edges, it goes much smoother and the holes become really nice! I have a package of those from 4-12mm for fine drilling ;-)
A hammer drill is perfect because it doesn't hit like a rotary hammer.
No cooling is needed, it drills quickly in brick.
Any machine should do the job, even a cheap one, but choose good drill bits, not the cheapest ones where you get a whole jar for 30, 40 kr.

It works excellently with a rotary hammer, but let the machine do the job and use carbide drills of good quality.

If it concerns regular bricks, the holes are best made with standard spiral drill bits for metal. It wears on the drill bit, of course, but you can use some cheap drill bit. A regular drill is sufficient, no hammer action needed.
