This. Even on my top of the range Makita combi, I'll almost always grab the SDS to drill into masonry, unless its incredibly soft material.

I drilled into engineering bric, topping my front wall, with my Makita, about 2" deep. Took 10 minutes for each hole I reckon and Christ the noise...

I dont have this issue with the milwaukee's, apart from they deafen you with how loud they are.
We use them all the time on brick and some of it is as hard as fuck.

The hammer drill action on a combi drill is never any good. The way it works on a combi drill is there are two serrated plates that engage and as the chuck turns these are pushed together which in turn pushes the bit into the wall. Doing it this way generates more noise than forward motion and the noise made is of a frequency that means it travels pretty well through solid walls so you'll be pissing off the neighbours.
An sds on the other hand has two motors one turning the Chuck and bit, the other turning a cam which drives the bit forward. It's more efficient, drills a lot quicker - especially in stone walls and makes much less noise.
If I owned a flat in a building like yours my first DIY purchase would be an sds and some quality bits to go with it.
This is a good buy and if used for DIY will likely out-live you.
