Which is better for drilling concrete?

The DCD1007B. It delivers up to 2,100 in-lbs of max torque and 38,250 BPM, well above the DCD798D1's 404 unit watts out and 28,050 BPM. For occasional small anchor holes, the kit is enough.

Is the DCD1007B worth the extra money?

Only if you already own 20V MAX batteries. Its $145.00 price at Walmart as of November 4, 2026 does not include a battery or charger, so the real cost is higher than the DCD798D1 kit at $115.59 at eBay.

Which one is lighter to use overhead?

The DCD798D1 at 2.49 lb and 6.93 in. The DCD1007B weighs 4.1 lb and is 7.6 in long, which is noticeable on ladders and ceilings.

Do both use the same batteries?

Yes. Both run on DEWALT 20V MAX lithium-ion packs, so batteries are interchangeable. The kit ships with one 2.0 Ah battery and a charger; the DCD1007B ships with neither.

Which has better kickback protection?

The DCD1007B. Its PERFORM & PROTECT system senses rotation from a bind-up and shuts the tool down. The DCD798D1 has no listed anti-rotation feature.

Both use brushless motors. The DCD1007B adds an all-metal transmission for heavy use, but the lighter DCD798D1 sees less strain in light drilling, so lifespan depends on the work.
