Where Size Meets Power: DEWALT ATOMIC 20V MAX* 4-1/2 Inch Brushless Cordless Angle Grinder

Tackle demanding metalworking and masonry tasks in the most restricted spaces with the DEWALT DCG402B ATOMIC™ 20V MAX* 4-1/2 Inch Angle Grinder. Engineered for professionals who require a high-performance tool without the bulk, this compact grinder delivers an impressive 760 MWO and 11,000 RPM (no-load speed) via its high-efficiency brushless motor. Its slim, ergonomic profile and reduced gripping diameter allow for superior maneuverability and access to ultra-tight corners that traditional grinders simply cannot reach. Whether you are cutting rebar, grinding welds, or prepping surfaces at height, this tool provides the untethered productivity of the 20V MAX* system with the rugged power of a corded unit.

Safety and control are prioritized through DEWALT's advanced ANTI-ROTATION System. This innovative feature monitors wheel movement and instantly shuts down the motor if a pinch, stall, or bind-up is detected, significantly reducing reactionary torque and protecting the user. Additionally, the integrated electronic brake is designed to stop the wheel in approximately 1.25 seconds after the trigger is released, ensuring a safer workspace. With Lanyard Ready™ attachment points for safety at height and a spindle lock for rapid, wrench-free wheel changes, the DCG402B is the ultimate jobsite companion for efficiency and operator protection. **Battery and charger sold separately.

Pro-Tip: To maximize the efficiency of your ATOMIC grinder, always ensure you are using the correct guard for the task—use the Type A clip-on for cutting and the Type B for grinding. This ensures optimal debris deflection and protects the brushless motor from unnecessary dust intake, significantly extending the tool's lifespan.
