Overview
The DEWALT DCG426B is a cordless 20 volt angle grinder spinning at 25,000 RPM and weighing 3 pounds.
The B in the model number marks this as a bare tool, the motor and grinder body without a battery or charger included. That matters for anyone comparing price against kit versions that bundle a battery, since this listing is tool-only.
- 25,000 RPM
- 20V cordless, bare tool
- 3 pounds
Who it's for
Fits DEWALT 20V MAX owners who already have batteries and a charger and just need the grinder head. Buyers without existing DEWALT batteries should budget for one and a charger separately or look at a kit version instead.
Pros and cons
- 25,000 RPM handles grinding and cutting work
- Light at 3 pounds for extended one-handed use
- Cordless 20V freedom from outlets and cords
- Bare tool, no battery or charger included
- Only useful if you already have 20V MAX batteries
Performance notes
At 25,000 RPM the grinder spins fast enough for cutting, grinding and surface prep work, and the cordless 20 volt design trades outlet dependence for battery run time. At 3 pounds it stays maneuverable for one-handed use on smaller jobs.
