DEWALT DCK299D1W1 Drill Combo Kit vs DeWalt DCK2100P2 20V MAX Combo Kit

Buy the DCK299D1W1 if you want the most powerful drill in the box today. Its DCD998 hammer drill with the included 8.0Ah battery delivers more torque than the DCD999 on any 20V pack, and the kit ships with a big battery plus a compact one. The DCK2100P2 is the better long-term pick if you plan to add FLEXVOLT batteries: the DCD999 then out-powers the DCD998, and two 5.0Ah packs suit all-day driving. Both kits share the same DCF887 impact driver, so the drill and batteries decide it. Owners rate the DeWalt 20V XR line highly for brushless motors and metal chucks; the trade-off is weight, since the 8.0Ah pack makes the DCD998 noticeably heavier.

• Choose the DCK299D1W1 if you want maximum drill power out of the box and a mix of one high-capacity and one compact battery.
• Choose the DCK2100P2 if you already own or plan to buy FLEXVOLT batteries and want two matched 5.0Ah packs.
