The DEWALT DCG413FB 20V MAX XR angle grinder is a 5-inch cordless model designed with an electronic brake and a flathead paddle switch. Its brushless motor requires no brush changes and delivers the runtime and power needed for cutting, grinding, and surface prep. The brake stops the wheel in 2 seconds or less on average, and the Kickback Brake engages maximum force to stop the wheel if it detects a pinch, stall, or bind-up. This is a tool-only package for users who already own 20V MAX batteries.
The two-stage trigger requires two actions to activate, which helps prevent accidental starts. The flathead paddle switch is comfortable to use in different orientations. With no brushes to replace, this grinder reduces routine maintenance costs.
If the brake seems weak or is not stopping the wheel quickly, start by checking the battery voltage—a low battery can slow the brake response. Next, inspect the paddle switch for debris or incomplete engagement; a stuck or dirty switch may prevent the brake circuit from activating. If the switch cycles correctly but the wheel still coasts, the electronic brake module may need replacement. Because this is a safety-related component, we recommend contacting Workbench World support for warranty or repair guidance.
Remove the battery, blow out the switch area with compressed air, and check that the two-stage trigger moves freely. Do not force the trigger. If it still sticks, the switch assembly may need service. This can often be fixed with a clean, but if it's damaged, replacement is the safe route.

The DCG413FB's electric brake is not just a convenience. It reduces coast-down time after you release the trigger, helping you place the tool down sooner. The Kickback Brake adds a second line of defense when a wheel binds.
No carbon brushes to replace, less heat build-up, and more runtime per charge. That makes the tool lighter in your hands and cheaper to maintain over time.
5-inch wheels give you more cutting depth and a larger grinding surface than 4-1/2-inch wheels, but with a bigger footprint. The 20V MAX XR brushless motor keeps up with those larger wheels in most shop and site work.
Start by checking battery charge and the trigger switch. If both are fine, the electronic brake may need service. Do not use the grinder until the brake is reliable.
It is designed for 5 in wheels; using smaller wheels requires a different guard and is not recommended.
No, this is tool only. You need a DEWALT 20V MAX battery and charger.
Remove the battery, blow out debris with compressed air, and test the trigger. If it remains sticky, contact support.
It requires two motions to start the grinder, which reduces the chance of accidental start-up.
The brushless motor gives plenty of power and the brake stops the wheel almost instantly. It's cordless, so I can move around the shop. The battery fits my other Dewalt tools. The 5-inch wheel size is versatile. I use it for cutting and grinding. The brake is a huge safety feature. Highly recommend.
It's lightweight and easy to handle. The brake works well. I just wish the battery was included.
I have a lot of Dewalt tools and this grinder is among the best. The brushless motor is efficient. The brake stops the wheel in under 2 seconds as advertised. The grip is comfortable. It's well balanced. It makes quick work of rust and welds.
I use this on my job sites. The power is comparable to corded. The battery drains fast but I have spares. The brake is handy.
Works fine.
I used it to cut tile and it did great. It's a bit heavy, but manageable. The brake is a nice feature.
I've been a handyman for years and this is the best cordless grinder I've owned. The brake gives instant stop, which is great for safety. The brushless motor runs cool. It fits my Dewalt batteries perfectly. The trigger switch is smooth. It's a bit pricey but worth it.
It has great power, but it eats batteries. I need two 5Ah to get through a day. But it's a cordless, so that's expected.
