High Velocity Compact Metal Fabrication and Surface Conditioning
The DEWALT DCG400B ATOMIC 20V MAX 4-Inch Angle Grinder is a compact battery-powered metalworking tool engineered to deliver 755 MWO and a 12,500 RPM no-load speed for heavy-duty cutting and grinding. This cordless power tool features an advanced brushless motor that replaces 0.7 HP pneumatic alternatives while reducing overall tool weight to 4.34 pounds for enhanced maneuverability. The system incorporates an integrated electronic safety brake and an anti-rotation mechanism to protect operators from reactionary torque during wheel pinches or stalls in confined spaces.
**Battery and charger sold separately.
Best Used For:
- Structural Metal Cutting: Slicing through structural steel angles, rebar, threaded rods, and sheet metal panels with high-speed precision.
- Industrial Weld Grinding: Smoothing heavy weld beads, removing slag, and beveling pipe edges prior to structural joining.
- Surface Prep Conditioning: Stripping rust, scale, and paint from metal plates using standard wire cups or abrasive flap discs.
Key Performance & Safety Features
- Anti-Rotation Safety System: Sensors detect aggressive wheel binding or pinching to immediately cut power, minimizing tool twist.
- Rapid Electronic Brake: Automatic braking assembly forces the abrasive wheel to a complete stop in less than 1.15 seconds upon trigger release.
- Convertible Guarding System: Includes a Type B grinding guard alongside a tool-free Type A clip-on guard for rapid cutting transitions.
- Paddle Switch Architecture: Ergonomic paddle trigger integrates a safety lock-off mechanism without a lock-on option to prevent accidental startup.
- Forward Exhaust Porting: Vent paths route spent internal cooling airflow and structural debris entirely away from the operator's face.
