DEWALT DCK277D2 Drill & Impact Driver Kit vs DeWalt DCK299M2 Hammer Drill and Impact Driver Kit

Buy the DCK299M2 if you drill masonry, drive long fasteners or want the most torque and runtime. Its DCD996 hammer drill adds a hammer mode, a 3-speed all-metal transmission and 0-38,250 BPM, and its DCF887 impact driver delivers 1,825 in-lbs versus 1,500 on the DCK277D2. The DCK277D2 is the lighter, simpler kit: a 340 UWO drill/driver and a 2.0 lb impact driver that fit tight spaces, with 2.0 Ah batteries that suit light to medium work. Reviewers of the DCK299M2 praise the power and battery life but note the hammer drill's 4.7 lb weight; owners of the DCK277D2 like the compact size and call the 2.0 Ah packs the main limit.

  • Choose the DEWALT DCK277D2 if you mostly drill wood and metal, drive screws, and want a compact, light kit that is easy to carry and store.
  • Choose the DEWALT DCK299M2 if you drill concrete or brick, drive large fasteners, or want maximum torque and longer runtime from 4.0 Ah batteries.

What reviewers say

DEWALT DCK277D2 Drill & Impact Driver Kit

Reviewers who are happy with the kit praise its power, smooth triggers, long battery life and LED lights, and several call it good value for beginners and general jobs. A minority report quality-control problems, including a dead battery or broken driver out of the box, and one buyer says the included batteries differ from the product description.

What people mention
  • PowerPraisedOwners say both tools drive screws and bore holes with little effort for their size.
  • Trigger feelPraisedReviewers describe the variable-speed triggers as smooth and easy to control.
  • Battery lifePraisedHappy owners report the 20V batteries lasting through long jobs.
  • Out-of-box faultsCriticisedSome buyers received a dead battery or a broken driver in the kit.

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 concrete?
The DCK299M2. Its DCD996 hammer drill has a hammer mode with 0-38,250 BPM. The DCK277D2 drill/driver has no hammer function and is not meant for masonry.
Which has more power?
The DCK299M2. Its impact driver makes 1,825 in-lbs versus 1,500 on the DCK277D2, and its hammer drill has a 3-speed all-metal transmission.
Which is lighter to carry around?
The DCK277D2. Its impact driver weighs 2.0 lb and its drill is 7.52 in long, against 3.4 lb and 4.7 lb tools in the DCK299M2.
Is the DCK299M2 worth stepping up to?
Yes if you drill masonry, drive large fasteners or work all day. The 4.0 Ah batteries and hammer mode do more. For light home drilling and screwdriving, the DCK277D2 covers it in a smaller package.
Do both kits include batteries and a charger?
Yes. The DCK277D2 includes two 2.0 Ah batteries, a charger and a contractor bag. The DCK299M2 includes two 4.0 Ah batteries, a charger and a hard case.
Which lasts longer on a charge?
The DCK299M2, because its 4.0 Ah packs hold twice the capacity of the 2.0 Ah packs in the DCK277D2. Both use brushless motors.
