Which is better for a homeowner starting out?

The DCK751P1. Seven tools cover drilling, sawing, sanding and cutting for one price, and you avoid buying each tool separately. The DCF845P1 only drives fasteners.

Which impact driver is stronger?

The DCF845P1. It delivers 1,825 in-lb versus 1,500 in-lb on the DCF787 in the combo kit, plus 3,400 RPM and 4,200 IPM.

Is the combo kit worth the extra money?

If you need three or more of its tools, yes. At $749.00 it costs about 5.5 times the $136.99 driver kit, but six extra tools would cost far more bought separately.

Do both use the same battery?

Yes. Both include the DCB205 20V MAX 5.0Ah lithium-ion battery and a charger, so batteries interchange across the 20V MAX line.

Both use brushless motors. The DCF845P1 carries a 3-year limited warranty; the combo kit's warranty is not stated in the listing. Buyers of the DCF845P1 report the grip rubber peeling over time.

Can I add the DCF845P1 to the combo kit?

Yes. It runs on the same 20V MAX battery, so it works alongside the kit's tools if you want more fastening torque later.
