DEWALT DCK277D2 Drill & Impact Driver Kit vs SKIL CB8437B-10 20V PWRCORE 20 Brushless Compact Lithium-Ion Cordless Drill Driver and Impact Driver Combo Kit

The DEWALT DCK277D2 is the safer buy for most people: two batteries, a contractor bag, and a brand with deep service and accessory coverage. The SKIL CB8437B-10 wins on raw impact torque and its light, compact feel, but it ships with one battery and no case, and owners report the direction switch is easy to bump. Buy DEWALT for a two-battery kit that covers a full day; buy SKIL if you want more torque and lighter tools and can live with one battery.

  • Choose the DEWALT DCK277D2 if you want two batteries, a bag, and a kit that covers drilling and driving without stopping to recharge.
  • Choose the SKIL CB8437B-10 if you want more impact torque and lighter tools for overhead work and already own spare 20V batteries.

Questions and answers

Which is better for driving long screws and lag bolts?
The SKIL. Its impact driver is rated at 1,800 in-lbs against 1,500 for the DEWALT, so it drives heavy fasteners with less effort.
Which kit lasts longer on a job?
The DEWALT, because it includes two batteries. The SKIL ships with one, so you recharge or buy a spare before a long day.
Do either of these drill into concrete?
No. Neither has a hammer function. For concrete and brick you need a hammer drill or rotary hammer.
Is the SKIL worth stepping up to over the DEWALT?
Only if impact torque and light weight matter more than a second battery and a bag. Otherwise the DEWALT kit is the more complete package.
Which has better owner feedback?
The SKIL holds 4.7 of 5 from 89 ratings, with praise for torque, lights and charging. The main complaint is the direction switch moving too easily. DEWALT has the larger track record and service network.
Can I share batteries between the two brands?
No. DEWALT 20V MAX and SKIL PWRCORE 20 batteries are not cross-compatible, so each brand locks you into its own packs.
