The DeWALT DCG422B 20V MAX ATOMIC Right Angle Die Grinder with DCB240 4.0Ah Compact Battery pairs DEWALT's cordless right angle die grinder with a 20V MAX 4.0Ah compact battery. This is a die grinder designed for grinding, deburring, surface prep, and light cutting in tight metalworking spaces. Bundle Model Number: DCG422B-DCB240.

The DCG422B is a cordless replacement for many pneumatic die grinder jobs. DEWALT rates it at up to 455 MWO (maximum watts out), so you can do a lot of air-tool work without dragging a compressor hose. That matters for mobile service work, punch lists, fabrication shops, and any job where managing a hose slows you down.

The control features matter in the awkward positions a right angle grinder ends up in. The ANTI-ROTATION System quickly stops the wheel when the tool senses a pinch, stall, or bind-up, which reduces kickback torque. The electronic brake stops the wheel in less than 1 second after trigger release, so you can move between grind points without waiting for the accessory to spin down. A variable speed trigger gives you finer control on edges and light cleanup.

The grinder uses a 1/4 inch collet and a brushless motor, and its glass-filled nylon housing is built to hold up to oils and harsh solvents found in automotive shops and maintenance work. It is TOOL CONNECT Chip Ready for optional asset tracking (chip sold separately).

The included DCB240 20V MAX 4.0Ah compact battery delivers 80 watt-hours in the same size and weight as the DCB230 3.0Ah compact battery. It is lighter than the DCB204 4.0Ah battery at the same capacity. On a tool you hold up under a vehicle or inside a cabinet, the smaller pack reduces fatigue. It has a 3-LED fuel gauge so you can check charge before you start.

This bundle is for automotive techs, welders, fabricators, and maintenance crews who already own a DEWALT 20V MAX charger and want a cordless die grinder ready to run. It is not built for heavy stock removal like a full-size angle grinder. Buy it for access, control, and mobility.
