Overview
The DCG418B is DeWalt's 60-volt cordless grinder, running at 9000 RPM. The listed item weight is 454 grams, though DeWalt's 60V grinders in this class typically weigh close to a couple of kilograms bare, so that figure may reflect a component rather than the full tool.
60-volt cordless grinders like this one target jobs that would otherwise need a corded angle grinder, trading a cord for battery power at DeWalt's higher voltage tier. No seller description is provided, and the weight figure listed looks low next to DeWalt's published specs for this model, so treat it cautiously.

Who it's for
Fits users on DeWalt's 60V FlexVolt battery system who want a cordless grinder for cutting, grinding, or surface prep. Not for anyone outside the DeWalt 60V ecosystem, since battery compatibility is specific to that platform.
Strengths and trade-offs
Drawn from this product's published specifications.
- 60-volt FlexVolt power for cordless grinding
- 9000 RPM matches corded grinder speeds
- Listed weight looks inconsistent with typical specs for this model
- Battery not included in this listing
Performance notes
9000 RPM at 60 volts puts this in line with corded angle grinder speeds, suited to cutting and grinding metal or masonry. As with any bare cordless tool, real world runtime depends on the battery used, which is not part of this listing.
