Which is better for drilling concrete?

The DCD1007. Its 38,250 BPM, 2,000 RPM, and 2,100 in-lbs of torque make faster work of concrete and masonry than the DCD798B's 28,050 BPM and 330 in-lbs.

Which is better for overhead work and tight spaces?

The DCD798B. It weighs 2.49 lbs bare against 4.1 lbs, and its head is 6.93 in against 7.5 in, so it is easier to hold up and fit between studs.

Is the DCD1007 worth about $75 more?

Yes if you drill concrete or large holes often. The extra torque, third speed, and anti-rotation safety are real gains. For light home drilling, the DCD798B covers it for less.

Do either come with a battery?

The DCD798B listing is tool only, with no battery or charger. The DCD1007 listing includes a battery and charger, so check which version you are buying before comparing prices.

The DCD1007 is built for heavier duty, with an all-metal 3-speed transmission and a nitro-carburized chuck with carbide inserts. The DCD798B is a lighter-duty tool, so heavy concrete work will wear it faster.

Can the DCD798B handle masonry?

Yes, in hammer mode at up to 28,050 BPM, but it is best for small holes and occasional anchors. Large-diameter concrete drilling is the DCD1007's job.
