Which is better for drilling into concrete?

The KC18DFX. Its hammer drill has a hammer mode the Sub-Compact drill lacks. The Sub-Compact is a drill/driver only.

Is the KC18DFX worth $70 more?

Yes if you need an impact driver or hammer drilling. You get a second tool, 1,328 in-lbs of driving torque and larger 2.0Ah batteries. For light assembly work, the $99 kit covers it.

Which is lighter to use overhead?

The Sub-Compact at 2.7 lbs with battery. The KC18DFX drill body alone is 2.9 lbs, and its impact driver is 2.2 lbs.

Do both use the same batteries?

Yes. Both are part of the Metabo HPT MultiVolt system, so 18V batteries interchange, and the KC18DFX tools also accept the 18V/36V MultiVolt battery.

Which has better runtime per charge?

The KC18DFX, with 2.0Ah batteries versus 1.5Ah in the Sub-Compact kit. The Sub-Compact charger refills a battery in about 40 minutes.

The KC18DFX carries a lifetime tool body warranty on both tools, and owners report long-term reliability. The Sub-Compact kit's warranty terms are not stated in its listing.
