Which kit is better for framing and deck building?

The XR kit. Its 7-1/4 in. circular saw cuts 2-9/16 in. deep at 90 degrees, and the 5.0Ah batteries keep it running through repeated cuts. The DCK620D2's 6-1/2 in. saw and 2.0Ah packs are fine for trim and occasional boards.

Do the batteries interchange between the two kits?

Yes. Both use the DeWalt 20V MAX battery system, so packs and chargers work across both kits and other 20V MAX tools.

Is the XR kit worth the extra money?

For daily trade use, yes. Brushless motors, 5.0Ah batteries, a hammer drill and a multi-tool are worth more than the roughly $50 gap between $599.99 and $650.00 at eBay as of November 4, 2026. For occasional home repairs, the DCK620D2 is enough.

Which has better runtime on the saws?

The XR kit. Its brushless circular saw and recip saw paired with 5.0Ah packs run longer than the brushed DCS393 and DCS381 on 2.0Ah packs.

Can the DCK620D2 drill into concrete?

No. The DCD780 is a drill/driver with no hammer mode. The XR kit's DCD996 hammer drill handles light masonry with the right bit.

Which kit is better for a homeowner starting out?

The DCK620D2. It costs less, covers drilling, driving and cutting, and the lighter 2.0Ah batteries are easier to handle. Add a 5.0Ah pack later if runtime becomes a problem.
