Our take on the DEWALT DCG407B 20V MAX XR Brushless Cordless 4-1/2"–5" Angle Grinder with Kickback Brake and E-Clutch, Tool Only

The DeWalt DCG407B is a 20V MAX XR brushless angle grinder that runs 4-1/2 to 5 inch wheels at up to 9,000 RPM and 850 MWO. It carries DeWalt's Kickback Brake and E-Clutch, which cut power and stop the wheel in a bind-up, plus an electronic brake. It is a bare tool, so batteries and charger are sold separately. At $115 at eBay as of November 5, 2026, it sits at the low end of its recent range across the four stores listing it new.

Pros
  • Brushless motor rated up to 850 MWO and 9,000 RPM
  • Kickback Brake and E-Clutch reduce injury risk in a stall
  • Electronic brake stops the wheel quickly after release
  • Runs 4-1/2 and 5 inch wheels, so one tool covers both
  • Slide switch with lock-on for long grinding passes
  • DeWalt claims up to 56 cuts of 1/2 inch rebar per charge
Cons
  • Bare tool: no battery or charger in the box
  • Barrel grip and slide switch suit some hands better than a paddle switch
  • Cordless runtime depends on which 20V pack you own
  • Heavier than a corded 4-1/2 inch grinder with a small pack

What reviewers say

Reception is thin: the listing shows a single 1-star rating, too little to judge the tool. DeWalt's cordless grinders with Kickback Brake generally draw praise for safety electronics and power, with runtime and bare-tool pricing as the usual complaints.

Pros
  • Kickback Brake and E-Clutch seen as real safety gains
  • Brushless motor holds speed under load
  • Tool-free guard and wheel changes
Cons
  • Short runtime on small batteries
  • Bare-tool price adds up once batteries are bought
  • Vibration over long grinding sessions

About the DEWALT DCG407B 20V MAX XR Brushless Cordless 4-1/2"–5" Angle Grinder with Kickback Brake and E-Clutch, Tool Only

Questions and answers

Is the DCG407B worth it over a corded grinder?
If you work on jobsites without power or move between locations, yes. A corded 4-1/2 inch grinder costs less and never runs out of power, so shop and garage users may not gain much.
What comes in the box?
The bare tool only: the grinder, a side handle and a wrench. No battery, charger or case, and no wheel.
Does it take 5 inch wheels?
Yes. It accepts 4-1/2 and 5 inch wheels with the standard 7/8 inch arbor, and the guard adjusts tool-free.
How long does it run on a battery?
DeWalt rates it at up to 56 cuts of 1/2 inch rebar. Real runtime depends on the pack: a 5.0Ah 20V MAX battery lasts far longer than a 2.0Ah compact.
What is the difference from the DCG405?
The DCG407B adds the E-Clutch and Kickback Brake electronics and a slide switch. The DCG405 is the older, simpler model without those safety features.
When is it cheapest?
Bare-tool prices swing with promotions. The $115 at eBay as of November 5, 2026 is near the bottom of the range across the four stores listing it new, so it is a fair time to buy.
Where is the DEWALT DCG407B 20V MAX XR Brushless Cordless 4-1/2"–5" Angle Grinder with Kickback Brake and E-Clutch, Tool Only cheapest?
At eBay, for $115.00, 36% under what the other stores charge, as of our latest check.
