The DEWALT DCG400S2 ATOMIC™ 20V MAX* 4-Inch Angle Grinder Kit delivers professional-grade cordless performance in a remarkably compact form factor, specifically engineered for fabricators, fitters, and welders who demand high power in confined workspaces. As part of the ATOMIC™ Compact Series, this tool provides the maneuverability of a pneumatic grinder with the untethered freedom of the 20V MAX* system. Featuring a high-output brushless motor and advanced safety systems, the DCG400S2 is the ultimate solution for metal cutting, grinding, and surface preparation where precision and power are non-negotiable.
Performance Features
- Brushless Motor Excellence: Delivers 755 Max Watts Out (MWO) and 12,500 RPM for high-speed cutting and grinding in demanding industrial applications.
- Compact ATOMIC™ Design: Engineered with a slim, ergonomic barrel grip that is 13% lighter than competitive pneumatic models, providing superior access to ultra-tight spaces.
- E-Clutch® & ANTI-ROTATION System: Integrated safety sensors quickly stop the motor and wheel when a pinch or stall is detected, significantly reducing reactionary torque for the user.
- Electronic Brake: Stops the wheel in approximately 1.15 seconds after the trigger is released, enhancing jobsite safety and productivity.
- Tool-Free Guard Conversion: Easily switch between a Type B guard and a Type A guard with the included clip-on system for rapid transitions between grinding and cutting.
- Forward Exhaust: Directs air and debris away from the user to prevent motor overheating and improve operator comfort.
- XR POWERSTACK™ Integration: Included 3.5Ah batteries provide higher power output and longer cycle life in a 25% more compact footprint than standard XR® batteries.
