DeWalt DCK277D2 Drill/Impact Combo Kit vs DeWalt DCK299M2 Hammer Drill and Impact Driver Kit

The DCK299M2 is the stronger kit. Its hammer drill adds masonry drilling, its impact driver delivers more torque, and the 4.0Ah batteries run longer between charges. The DCK277D2 is lighter and more compact, which suits overhead work and tight cabinets. Owners of both kits praise the brushless motors and the 3-year warranty; the main complaint about the smaller kit is battery runtime on big jobs.

  • Choose the DCK277D2 if you want a light, compact drill and impact driver for home repairs, cabinet work and overhead fastening, and you rarely drill concrete.
  • Choose the DCK299M2 if you drill masonry, drive long screws all day, or want the extra torque and runtime a pro job site demands.

What reviewers say

DeWalt DCK277D2 Drill/Impact Combo Kit

  • 4.8 / 592 ratings

Rated 4.8 out of 5 from 92 ratings, the kit is well received as a compact, light two-tool set on the 20V MAX platform. Owners value the brushless motors, the impact driver's torque and the tight-space handling.

What people mention
  • Size and weightPraisedOwners like how compact and light both tools feel, especially in tight spaces.
  • Impact torquePraisedThe impact driver's 1,500 in-lbs is seen as strong for a kit this size.
  • Battery run timeCriticisedThe 2.0Ah packs are called small for sustained drilling and driving.
  • Build and gripPraisedThe ergonomic grip and balance get good marks for control.

DeWalt DCK299M2 Hammer Drill and Impact Driver Kit

Owners of the DCD996 and DCF887 pair generally rate it highly for power, speed and build, and many call it a step up from older DeWalt kits. Complaints center on weight and on the drill's appetite for battery charge under heavy hammer use.

What people mention
  • PowerPraisedOwners say the impact driver drives long fasteners without bogging down.
  • BuildPraisedThe all-metal transmission and chuck are described as holding up to daily job-site use.
  • WeightMixedThe drill is compact but at 4.7 lb it tires arms during long overhead sessions.
  • BatteryMixedThe 4.0Ah packs last well in the driver, but hammer drilling drains them quickly.

Questions and answers

Which kit is better for drilling into concrete?
The DCK299M2. Its DCD996 hammer drill has a hammer mode with up to 38,250 BPM. The DCK277D2 drill has no hammer function and will struggle in masonry.
Which has more power?
The DCK299M2. Its impact driver makes 1,825 in-lbs against 1,500 in-lbs, and its hammer drill runs a 3-speed all-metal transmission.
Which is easier to use overhead?
The DCK277D2. Its drill weighs 2.6 lb and measures 7.6 in front to back, against 4.7 lb and 8.4 in for the hammer drill.
How much longer do the 4.0Ah batteries last?
Roughly twice as long as the 2.0Ah packs in the DCK277D2, since capacity is doubled. Expect fewer battery swaps on long drilling and fastening jobs.
Is the DCK299M2 worth stepping up to?
Yes if you drill masonry or drive screws all day. The hammer mode, extra torque, bigger batteries and hard case matter on job sites. For light home work the smaller kit is enough.
Do both kits use the same 20V MAX batteries?
Yes. Both run on DeWalt 20V MAX lithium-ion packs, so batteries and chargers work across either kit.
