The grinder’s safety mechanisms impressed us, especially the kickback Brake system that activates immediately during pinch or stall events, stopping the wheel in less than two seconds to minimize potential injury.

Key Features That Make This Grinder Stand Out
One of the most impressive aspects of this grinder is its brushless motor, which eliminates the need for brush changes and significantly extends the tool’s motor life. This not only reduces maintenance but also ensures consistent power and efficiency during use. Safety is a major focus here,with a Kickback Brake system that quickly stops the wheel in 2 seconds or less whenever a pinch,stall,or bind-up is detected. This feature drastically reduces the chance of sudden tool movement and helps protect us from potential injury by shutting the grinder off instantly during these events.
Additional safety and usability enhancements include the E-Switch Protection, which prevents the tool from restarting automatically after a power outage, requiring us to cycle the trigger to reactivate. The two-stage trigger adds another layer of user control, demanding two separate actions to start the grinder, so accidental activations are minimized. Compact and lightweight, this 4 1/2 inch cordless tool offers an ideal balance of power, maneuverability, and advanced safety features that enhance our everyday grinding tasks.
| Feature | Benefit |
|---|---|
| Brushless Motor | Longer motor life, less maintenance |
| Kickback Brake | Stops wheel in under 2 seconds, reduces kickback |
| E-Switch Protection | Prevents auto-restart after power failure |
| Two-Stage Trigger | Prevents accidental starts |
in-Depth Look at Performance and Usability
One of the standout features is the brushless motor, which not only extends the tool’s lifespan but also boosts efficiency by eliminating the need for brush replacements. This means less downtime and more consistent power delivery during heavy-duty tasks. We also appreciated the paddle switch with E-Switch Protection, designed to prevent accidental startups by requiring a two-stage action to engage. In practice, this adds an important layer of safety, especially on busy job sites or in unpredictable work environments.
safety remains a priority thanks to the innovative Kickback Brake system. When the grinder detects a pinch, stall, or bind-up, it quickly applies maximum force to halt the wheel in under two seconds. This rapid response not only reduces the risk of injury but also helps protect the tool from damage. Additionally, the device shuts off automatically in such events, offering peace of mind while pushing the grinder hard. Below is a quick snapshot of key performance and safety specs:
| Feature | Benefit |
|---|---|
| Brushless Motor | Longer motor life, maintenance-free operation |
| Kickback Brake | Stops wheel within 2 seconds, reduces kickback |
| E-Switch Protection | Prevents accidental starts with two-step activation |
| Automatic Shutoff | Enhances user safety during stalls or binds |

Our Recommendations for Getting the Most out of This Tool
To maximize performance and safety, always ensure you’re using the correct, fully charged battery compatible with the grinder, as the tool is sold without one. Take advantage of the brushless motor’s maintenance-free design by focusing your efforts on keeping the grinding wheel clean and sharp. Remember, the electronic kickback brake is an essential safety feature that reacts instantly during pinch or stall events-this means staying alert to changes in wheel movement is crucial. Additionally, the two-stage paddle switch with E-Switch protection requires a deliberate two-step activation, which helps prevent accidental starts, so make a habit of mastering this control for safer and more efficient operation.
For prolonged tool life and effectiveness,follow these simple best practices:
- Check the brake function regularly: Confirm the wheel stops within 2 seconds after releasing the switch.
- Use the correct guard and wheel size: Always fit a 4 1/2 inch grinding wheel and appropriate safety guard to prevent debris and injury.
- Cycle the trigger switch after power interruptions: This ensures safe restart due to the no-volt release function.
- apply consistent pressure: Avoid forcing the tool, letting the motor and brake system handle any bind-ups or stalls.
| Tip | Benefit |
|---|---|
| Use Paddle Switch Carefully | Prevents accidental startups |
| Allow Brake to Engage | Ensures quick wheel stop & user safety |
| Cycle Trigger After Outages | Maintains tool’s electronic protection |

Q&A
Q&A: Your Questions About the DEWALT 20V MAX Brushless Angle Grinder Answered
Q1: What makes the DEWALT 20V MAX Brushless Angle Grinder different from other cordless grinders?
We love that this grinder features a brushless motor, which means you don’t have to worry about replacing brushes over time. This not only extends the motor life but also improves overall efficiency and run time. Plus, it has advanced safety features like the Kickback Brake, which stops the wheel in 2 seconds or less during a pinch or bind-up, helping to protect us from sudden kickbacks.
Q2: Is the battery included with this angle grinder?
No, the DEWALT 20V MAX Brushless Angle Grinder (model DCG413B) is sold as a tool-only unit. That means the battery and charger are sold separately. If you already have other DEWALT 20V MAX tools, you can use the same batteries, which is really convenient for us who already own DEWALT cordless tools.
Q3: How does the Kickback Brake work and how effective is it?
The Kickback Brake is a standout feature for us. If the grinder senses a pinch,stall,or bind-up event – situations where the wheel could suddenly stop and cause the tool to kick back – the electronic brake activates with maximum force. It stops the wheel quickly, reduces the grinder’s movement, and shuts the tool off, significantly enhancing user safety.
Q4: What is the paddle switch and two-stage trigger, and how do they affect usage?
The paddle switch offers an ergonomic and easy-to-use design, requiring two separate actions to activate the tool. This two-stage trigger setup, along with E-Switch Protection, makes the grinder safer because it prevents accidental startups. Such as, if there is a power outage or the battery gets disconnected, the tool will require you to cycle the trigger off and on again before restarting, removing unexpected start hazards.

Because it’s cordless and powered by DEWALT’s 20V MAX battery system, it’s incredibly portable. We don’t have to worry about cords getting in the way or finding power outlets on the job site. The compact 4 1/2 inch wheel size is versatile and well-suited for a variety of cutting and grinding applications, making it a reliable tool for professionals and DIY enthusiasts alike.
Q6: Can we use this grinder for heavy-duty tasks?
While this grinder is powerful and equipped with a brushless motor, it’s designed for general-purpose grinding and cutting using a 4 1/2 inch wheel size. For extremely heavy-duty or industrial tasks, larger grinders might be more suitable, but for most of our everyday grinding, cutting, and metalwork needs, this tool performs excellently.
Q7: How durable is this grinder? Can it take the rigors of job site use?
Absolutely. DEWALT tools are known for their durability, and the DCG413B is no exception. The brushless motor requires less maintenance,and the robust housing along with advanced braking features ensures it withstands tough conditions. The quick brake feature also protects the internal components by stopping the wheel fast, which is a big plus for longevity.
Q8: Would this be a good choice for beginners?
Yes! The safety features like the Kickback brake, two-stage trigger, and E-Switch Protection make this grinder a great choice for users who might be new to angle grinders.
