Our take on the DeWalt DCG402B ATOMIC 20V MAX 4-1/2 in. Angle Grinder W/ DCB204-2 4.0Ah Battery 2-Pack

The DeWalt DCG402B is a compact 20V MAX cordless angle grinder with a 4-1/2 in. wheel, built for cutting and grinding in tight spots. Its slim body and narrow grip set it apart from full-size corded grinders, and an electronic brake stops the wheel within about 1.25 seconds of releasing the trigger. This bundle adds two 20V MAX XR 4.0Ah batteries, which DeWalt rates for up to 33% longer runtime than its standard packs. It suits tradespeople and DIYers already on the 20V MAX platform who want a light, maneuverable grinder rather than maximum power.

What reviewers say

Owners of the DCG402B generally like its compact size and quick brake for one-handed work in tight spots. The main complaints center on runtime with smaller packs and the lack of a charger in bare-tool kits.

What people mention
  • Size and gripPraisedOwners say the slim body and narrow grip make it easy to use in tight spaces.
  • Electronic brakePraisedReviewers like that the wheel stops quickly after the trigger is released.
  • RuntimeMixedBattery life is fine for quick jobs but short for sustained grinding, especially on smaller packs.
  • PowerMixedIt handles light cutting and grinding well but falls short of corded grinders on heavy work.
  • Kit contentsCriticisedBuyers note the grinder ships without a charger, so one must be sourced separately.

About the DeWalt DCG402B ATOMIC 20V MAX 4-1/2 in. Angle Grinder W/ DCB204-2 4.0Ah Battery 2-Pack

This bundle pairs the DeWalt ATOMIC 20V MAX 4-1/2 in. Angle Grinder (DCG402B) with a 20V MAX XR 4.0Ah battery 2-pack (DCB204-2). The batteries power the grinder, so it is ready to run out of the box. Each item is a genuine DeWalt 20V MAX product in its original packaging.

The grinder has a slim, ergonomic body with a smaller gripping diameter for access into tight spaces. It delivers up to 760 MWO. An electronic brake is designed to stop the wheel within 1.25 seconds after the trigger is released.

The XR lithium-ion battery packs provide up to 33% longer run-time than standard 20V MAX battery packs. A 3-LED fuel gauge shows the state of charge.

Questions and answers

Does this bundle include a charger?
No. It includes the DCG402B grinder and two DCB204 4.0Ah batteries, but no charger. You need a DeWalt 20V MAX charger, which many owners already have.
What size wheel does the DCG402B take?
It uses 4-1/2 in. wheels, the common size for compact angle grinders. That covers most cutting and grinding discs.
How does it compare with a corded grinder?
It is lighter and more maneuverable and needs no outlet, but a corded grinder delivers more sustained power for heavy grinding. The DCG402B is best for light to medium work and tight spaces.
Will the included batteries fit other DeWalt tools?
Yes. The DCB204 packs use the 20V MAX system, so they work in other DeWalt 20V MAX tools and chargers.
How long do the 4.0Ah batteries last?
DeWalt rates XR 4.0Ah packs for up to 33% longer runtime than standard 20V MAX packs. Actual runtime depends on the material and the load.
Is the grinder sold as a bare tool?
Yes. The DCG402B is a bare tool; in this bundle the two batteries are the only power accessories included.
Where is the DeWalt DCG402B ATOMIC 20V MAX 4-1/2 in. Angle Grinder W/ DCB204-2 4.0Ah Battery 2-Pack cheapest?
