Our take on the DEWALT DCG405B XR Slide Switch Small Angle Grinder with Kickback Brake 20V MAX - 4-1/2"

The DeWalt DCG405B is a cordless 4-1/2 in. angle grinder in DeWalt's 20V MAX XR line, sold as a bare tool. Its standout feature is the Kickback Brake, which stops the wheel in about 2 seconds or less when a pinch, stall or bind-up is detected, and shuts the tool off. A brushless motor means no brush changes, and Power Loss Reset prevents accidental restarts after a power interruption. It suits tradespeople and serious DIYers already on the 20V MAX battery platform who want a safer grinder for grinding, sanding and cutting metal. Against corded grinders it trades raw power for portability; against other cordless grinders its kickback brake and slide switch are the main draws.

What reviewers say

Owners of DeWalt's 20V MAX grinders generally rate the platform well for build and the kickback brake, and treat the bare-tool format as a way to reuse batteries they already own. The main complaints are that it is less powerful than a corded grinder for sustained heavy grinding and that the cutting guard is an extra purchase.

What people mention
  • Kickback brakePraisedOwners value the brake that stops the wheel quickly when the tool binds or stalls.
  • PowerMixedFine for typical grinding and sanding, but it trails corded grinders on sustained heavy work.
  • BuildPraisedThe brushless motor and overall construction are seen as durable.
  • SwitchPraisedThe slide switch is easy to operate, including with gloves.
  • Battery platformPraisedRuns on any DeWalt 20V MAX battery, which suits owners already on the system.
  • Cutting guardCriticisedCutting needs a Type 1 guard that is not included.

About the DEWALT DCG405B XR Slide Switch Small Angle Grinder with Kickback Brake 20V MAX - 4-1/2"

The DEWALT DCG405B is a cordless 4-1/2" small angle grinder with a slide switch. It is part of the 20V MAX XR line and works with all 20V MAX batteries. It is sold as a tool only.

A brushless motor means there are no brush changes. A Kickback Brake senses a pinch, stall, or bind-up. When it does, the electronic brake engages with maximum force to stop the wheel quickly, reduce the movement of the grinder, and shut it off. The brake stops the wheel in 2 seconds or less on average.

Power Loss Reset prevents accidental restarts after a power disruption when the tool is left in the "on" position. The grinder is used for grinding, sanding, and cutting. Cutting requires a 4.5-inch Type 1 guard, sold separately.

Questions and answers

Does the DCG405B come with a battery and charger?
No. It is a bare tool, so battery and charger are sold separately. It runs on any DeWalt 20V MAX battery.
Can I use it for cutting?
Yes, but cutting requires a 4-1/2 in. Type 1 guard that is sold separately. Out of the box it is set up for grinding and sanding.
What does the Kickback Brake do?
When the tool senses a pinch, stall or bind-up, the brake engages with maximum force to stop the wheel, reduce movement and shut the grinder off. DeWalt says it stops the wheel in 2 seconds or less on average.
What is Power Loss Reset?
If power is interrupted while the switch is left on, the tool will not restart by itself when power returns. You have to reset it, which prevents accidental starts.
Does it have a variable-speed dial?
No. This model uses a slide switch without a variable-speed dial, so speed is not adjustable.
What arbor size does it take?
It uses a 5/8-11 arbor, the common size for 4-1/2 in. grinding and cutting wheels.
