DeWalt ATOMIC 20V MAX 4-Tool Combo Kit vs DeWalt 20V MAX 9-Tool Combo Kit DCK940D2

Buy the ATOMIC 4-tool kit if you want compact, brushless tools for drilling and driving, and you value a lighter bag you can carry all day. Buy the 9-tool kit if you need a saw, grinder and oscillating tool for cutting, grinding and remodeling, and you accept brushed motors and a much heavier bag. Owners rate the ATOMIC kit slightly higher (4.6 vs 4.4), but the 9-tool kit has far more ratings and covers more jobs. The ATOMIC tools are sub-compact with brushless motors; the 9-tool kit's core drill and impact driver are older brushed designs rated at 300 UWO.

  • Choose the DeWalt ATOMIC 4-tool kit if your work is mostly drilling and driving and you want compact, brushless tools in a bag you can carry easily.
  • Choose the DeWalt 9-tool kit if you need saws, a grinder and an oscillating tool for cutting, grinding and remodeling, and you don't mind the extra weight.

What reviewers say

DeWalt ATOMIC 20V MAX 4-Tool Combo Kit

  • 4.6 / 5310 ratings

Rated 4.6 out of 5 from 310 ratings, the kit is well regarded as a compact, reliable starter set. Owners like the brushless power in a small body; the main complaints center on small batteries and the bag.

What people mention
  • SizePraisedOwners say the sub-compact bodies fit into tight spots and are easy to control one-handed.
  • Battery lifeCriticisedThe 2.0 Ah packs are seen as small, draining fast during sustained drilling or driving.
  • BuildPraisedBrushless motors and DeWalt build quality are described as durable for the price.
  • PortabilityMixedThe contractor bag holds everything but is heavy and bulky to haul around.

DeWalt 20V MAX 9-Tool Combo Kit DCK940D2

  • 4.4 / 5574 ratings

Rated 4.4 out of 5 from 574 ratings, buyers call the kit good value with a useful spread of tools and strong batteries. The main complaint is that the speaker and light crowd out tools they would have preferred.

What people mention
  • PowerPraisedBuyers say the tools have more than adequate power for their jobs.
  • Battery lifePraisedOwners report good battery life and a recharge of about 20 to 30 minutes.
  • Tool selectionMixedBuyers like the assortment but some would swap the speaker and light for other tools.
  • ValuePraised

Questions and answers

Which kit is better for drilling and driving only?
The ATOMIC 4-tool kit. Its brushless drill and impact driver are compact and efficient, and you don't pay for saws you won't use.
Which kit is better for remodeling and demolition?
The 9-tool kit. It adds a reciprocating saw, circular saw, grinder and oscillating tool, which the ATOMIC kit lacks.
Which lasts longer?
The ATOMIC tools should, because brushless motors have fewer wear parts. The 9-tool kit's brushed drill and impact driver will need brushes and motor service sooner under heavy use.
Is the 9-tool kit worth stepping up to?
Only if you need cutting and grinding. If you mostly drill and drive, the ATOMIC kit is lighter, brushless and better rated by owners.
Do both kits use the same batteries?
Yes. Both are 20V MAX kits with two 2.0 Ah lithium-ion packs and a charger, so batteries and chargers interchange across the DeWalt 20V MAX line.
