Overview
The DCG413FB is a cordless angle grinder from DEWALT's 20V Max line, built around an 800 watt motor that spins the wheel at 9000 RPM. At 4.61 pounds it sits in the lighter end of the battery grinder class, suited to trim and cleanup work rather than continuous heavy grinding.
Battery power removes the cord from a job where sparks and metal dust are already a hazard, at the cost of runtime tied to whatever battery pack is paired with it. DEWALT sells many 20V Max tools as bare units, so check whether a battery and charger are included before ordering. The 9000 RPM top speed is on par with corded grinders in this wheel size.
- 20 volt battery powered motor
- 9000 RPM no load speed
- 800 watt motor output
- 4.61 pound tool weight
Who it's for
Fits tradespeople who already carry 20V Max DEWALT batteries and want one more tool on the same platform, or anyone doing occasional metal cutting and deburring around a shop or job site. It is not sized for grinding jobs that run for hours without a battery swap.
Pros and cons
- Cordless operation on the 20V Max platform
- 9000 RPM matches corded grinder speeds
- Light enough at 4.61 pounds for one handed control
- Runtime depends on a separately sold battery pack
- 800 watts is modest for heavy stock removal
Performance notes
The 800 watt motor and 9000 RPM speed put this in line with typical 4.5 to 5 inch angle grinders, delivering enough speed for cutting, grinding and deburring metal. Because it runs on battery rather than a cord, actual working time depends on the amp hour rating of the pack used, which is not specified in this listing.
