Part of DEWALT's PERFORM & PROTECT line, the DCG405B is a brushless small angle grinder that stops the wheel in 2 seconds or less when a pinch, stall, or bind-up is detected. The brushless motor requires no brush changes and offers a longer life. Power Loss Reset prevents accidental restart after a power disruption.
No. The DCG405B is designed for 4-1/2-inch (115mm) Type 27 wheels. Using a 5-inch wheel can exceed the guard's capacity and create an unsafe condition. Stick with 4-1/2-inch wheels for proper fit and safety.
The Kickback Brake is designed to engage when the grinder detects a pinch, stall, or bind-up. If it engages frequently, check for a damaged or worn wheel, excessive side pressure, or a partially discharged battery. Always use a sharp wheel and let the grinder do the work.
This tool-only package includes (1) DCG405 grinder, (1) side handle, (1) hex key, (1) inner and outer flange, and (1) 4.5-inch Type 27 guard.
The brushless motor eliminates brush replacement and improves runtime. The kickback brake brings the wheel to a stop quickly, improving control and safety.

The DCG405B is designed to help you stay productive and safe. The Kickback Brake is a game changer for anyone who has fought a runaway grinder.
An internal sensor detects when the wheel is pinched or stalled. Within milliseconds, the brake applies maximum stopping force to stop the wheel and reduce the grinder's movement. This helps you keep control.
For cutting, use a thin cut-off wheel. For grinding, use a thicker grinding wheel. Always match the wheel to the tool's RPM rating and size.
Keep the spindle threads clean and check the guard regularly. Replace worn flanges and ensure the brushless motor has good airflow.
No, the DCG405B is designed for 4-1/2-inch wheels only. Using a larger wheel can be dangerous and may damage the tool.
This indicates the grinder detected a bind-up. Check for a pinched or damaged wheel, reduce pressure, and ensure the battery is fully charged. If it continues, contact support.
The maximum recommended wheel size is 4-1/2 inches (115mm).
No, it's sold as tool only. Use any DEWALT 20V MAX battery.
This grinder is a beast. The kickback brake gives me confidence. Highly recommend.
I'm a beginner and this grinder is so easy to use. It stops quickly if it kicks. Love it!
It's a solid machine but takes a bit to get used to the brake.
The kickback brake is the reason I bought this. It's prevented a couple of accidents already. The power is great for cutting metal.
Does the job.
It eats batteries, but the tool itself is fine.
I've been in construction my whole life. This grinder is as good as any corded one. The brake is a smart addition.
I used it to cut rebar and it went through like butter. The brake is a lifesaver.
It's a well-built grinder, but it's a bit heavy for one-handed use.
I'm a hobbyist and this is my first angle grinder. The brake makes me feel safe. It's also very smooth.
I don't use it often but it works when I need it.
This is a great grinder. The power is consistent and the brake is instant. I've used other brands but this one is my favorite. It's worth the premium.
