- Is this kit worth it over a cheaper brushed combo?
- Yes for regular use. Brushless motors last longer and run more efficiently, and both tools share the 20V MAX platform, so later bare tools fit the same batteries.
- How long do the 2.0Ah batteries last?
- Expect short runtime under continuous load, such as driving long deck screws. For heavy days, plan on 4.0Ah or 5.0Ah packs, which fit the same tools.
- Can the impact driver drill holes?
- Only with hex-shank bits. For round-shank drill bits and precise hole sizes, use the drill/driver with its keyless chuck.
- Does it work with other DeWalt 20V batteries?
- Yes. Any DeWalt 20V MAX pack fits both tools, including the larger capacity packs sold separately.
- What is in the box?
- The kit includes the drill/driver, the impact driver, two 2.0Ah batteries and a charger. Confirm whether a case or bag is included before buying.
- Is it good for masonry or concrete?
- No. Neither tool has a hammer mode; for concrete you need a rotary hammer.
- Where is the Dewalt DCK661D1M1 (2x2.0Ah) cheapest?
- At The Home Depot, for $799.00, as of our latest check.
