Which is better for drilling into brick or concrete?

The KC18DFX. Its DV18DFX hammer drill has a hammer mode the DS18DFX lacks. The DS18DFX is a drill driver only.

Do I need the impact driver?

If you drive long lag screws or lots of deck screws, yes. The WH18DFX puts out 1,328 in-lbs, far more than the DS18DFX's 470 in-lbs. For furniture and light assembly, the DS18DFX is enough.

Is the KC18DFX worth $70 more?

Yes if you would otherwise buy a second tool and battery. At $169.00 you get two tools and two batteries; the DS18DFX is $99.00 with one battery. If you only need one drill, the DS18DFX is the better spend.

Both carry Metabo HPT's lifetime tool body warranty and share the MultiVolt battery system. The KC18DFX has two batteries, so you cycle each less. Long-term owners of the kit report it holding up over months and years of use.

Can I use the same batteries on both?

Yes. Both use 18V MultiVolt slide packs, and both accept the 18V/36V MultiVolt battery for longer runtime. A 2.0Ah pack from either kit fits either tool.

Which is lighter to use overhead?

They tie on the drill: both bodies weigh 2.9 lbs. The KC18DFX impact driver is lighter still at 2.2 lbs. The DS18DFX kit carries less in the bag because it has one tool and one battery.
