I find myself needing to do more and more stucco and concrete chipping work that is suitable for purchasing a rotary hammer. Can anyone here tell me if such tools can entirely replace a normal drill? On paper, it seems like they can; they can do pure drilling, hammer drilling, or non-rotating chipping. I'm an efficiency-minded kind of guy, so if it's possible to replace my drill with a high-quality do-it-all machine, I'd really like to. Off the top of my head, I can imagine two drawbacks to using a rotary hammer for everything:

1. They are heavier than regular drills.
2. You need to use an adapter to use regular non-SDS drill bits, further increasing the weight, and there's more slop since the adapter will slide up and down a bit.

Are there more downsides? Is it indeed feasible to use a rotary hammer for everything?
