Our take on the DEWALT 20V MAX Cordless 4 1/2 Inch Slide-Switch Power Angle Grinder, Bare Tool Only (DCG407B)

The DeWalt DCG407B is a bare-tool 4-1/2 inch angle grinder built on the 20V MAX battery platform. Its brushless motor delivers up to 850 MWO and 9,000 RPM no-load speed, and DeWalt rates it for up to 56 cuts of 1/2-inch rebar per charge. A slide switch, kickback brake and E-Clutch anti-rotation electronics put it ahead of older brushed 20V grinders on safety and runtime. At 3.55 lb bare, it suits tradespeople already on the 20V MAX line who want a light grinder for cutting and light grinding; it is not a substitute for a corded 13-amp grinder on heavy continuous work.

Pros
  • Brushless motor with 850 MWO and 9,000 RPM no-load speed
  • Kickback Brake and E-Clutch cut power on bind-up
  • Rated for up to 56 cuts of 1/2-inch rebar per charge
  • Light at 3.55 lb bare tool
  • Slide switch is easier to use with gloves than a paddle
Cons
  • Bare tool: battery and charger sold separately
  • Slide switch is easier to bump than a paddle switch
  • 4-1/2 inch wheel limits depth of cut versus larger grinders
  • Runtime depends heavily on which 20V MAX battery you use

What reviewers say

Owners of DeWalt's 20V MAX brushless grinders generally rate the platform well for cutting and light grinding, praising the power-to-weight balance and the anti-kickback electronics. Criticism tends to focus on the bare-tool packaging and on runtime with smaller batteries.

What people mention
  • PowerPraisedOwners say the brushless motor cuts rebar and steel quickly for a cordless tool.
  • WeightPraisedReviewers like the low bare-tool weight for one-handed and overhead use.
  • Safety electronicsPraisedThe kickback brake and E-Clutch are cited as real confidence boosters when a wheel binds.
  • SwitchMixedThe slide switch is easy to operate with gloves but some users find it easier to bump than a paddle.
  • Battery runtimeMixedRuntime is good with larger packs but noticeably shorter with compact batteries.
  • Bare toolCriticisedBuyers note the tool arrives without a battery or charger, adding to the real cost.

Questions and answers

Does the DCG407B come with a battery?
No. It is a bare tool, so battery and charger are sold separately. Any DeWalt 20V MAX pack works.
How does it compare with the older DCG413?
The DCG407B adds a brushless motor rated at 850 MWO and 9,000 RPM with Kickback Brake and E-Clutch, where the DCG413 is a brushed model with a paddle switch.
What size wheels does it take?
It uses 4-1/2 inch (115 mm) grinding and cutting wheels with a 7/8 inch arbor.
Is it good for cutting rebar?
Yes. DeWalt rates it for up to 56 cuts of 1/2-inch rebar per charge, though actual count depends on the battery used.
Slide switch or paddle switch?
This model has a slide switch on the side of the body, which is easier to work with gloves but can be bumped more easily than a paddle.
Can it run on any DeWalt 20V MAX battery?
Yes. It fits the 20V MAX lineup, and larger-capacity packs give longer runtime at more weight.
