Which is better for driving screws?

The combo kit. Its impact driver puts out 1,700 in-lbs, far more than the DCD793D1 drill's 404 UWO. The drill can drive screws, but the impact driver does it faster and with less wrist strain.

Is the DCD793D1 worth it if I already have DEWALT 20V batteries?

Yes, if you only need a drill. It is $99 at Lowe's as of November 4, 2026, and both tools use the same 20V MAX batteries and chargers.

The DCD793D1 should, because brushless motors have no brushes to wear out. The combo kit's brushed motors are proven but need more maintenance over years of heavy use.

Do I need both tools?

Only if you fasten often. For drilling holes and occasional screws, the DCD793D1 covers it. For decking, framing or lots of screws, the impact driver in the combo kit saves time.

Which is the better deal right now?

The DCD793D1 at $99.00 at Lowe's as of November 4, 2026 is the lower price. The combo kit at $129.00 at Amazon as of November 4, 2026 gives you a second tool and a second battery for $30 more.
