Note this tool takes specialized SDS-Plus drill bits, concrete bits for normal drills and SDS Max bits are not compatible.
I'd use that for anything under half an inch. After that, I'll just pull out the SDS Max.
As for 3" holes with an SDS-Plus, not in my experience. I suppose it depends on the concrete, but I hammered away on old concrete for five minutes and got all of a quarter inch in. It was before I had the SDS Max, and it was easier to just break that section of the walkway and pour new concrete around the hole I needed. I ran four 1 3/4" holes through similarly aged walkways, and it took a good 5 minutes each with SDS-Max.

No idea why it was on clearance at some Lowe's stores when it wasn't discontinued but I found out from SlickDeals.

Making larger holes with a core bit (concrete hole saw) for things like conduit or a drainage pipe through cinder block is where you'll definitely want an SDS+ instead, but you also get to use the hammer part for breaking up rocks, removing tile, and so many other non-drill tasks. Heck, SDS Max is even used for driving ground rods deep in the ground! Closest thing to a cordless air hammer.

SDS Plus rotary hammers slot right in there where you could use it for a lot of the same things you'd use a traditional hammer drill for but you won't be driving 12' ground rods into the ground with them like you might with an SDS Max. The DCH133 is also kinda long to use for some of the things you'd use a traditional drill for. Like, I wouldn't use it for framing or working under the kitchen sink.They do make shorter SDS Plus rotary hammers with shock absorption. They are more expensive even though the DCH133 often outperforms them. This guy does a lot of comparisons and he really likes it:
