DEWALT 20V MAX XR Angle Grinder Review Power and Safety Features Explored

Description

Performance and Power of the DEWALT 20V MAX* XR Angle Grinder

Testing the DEWALT 20V MAX* XR Angle Grinder with Kickback Brake, Slide Switch, 4-1/2-Inch, Tool Only (DCG405B) on various surfaces, I was impressed by its brushless motor that delivers 850 watts of power and spins at a maximum speed of 9000 revolutions per second. This powerful tool handled metal cutting and grinding without overheating or losing torque. The brushless design not only means I avoided frequent brush replacements but also contributed to a longer motor life, which is a huge plus for anyone using this grinder regularly.

The kickback brake feature truly stands out. During one test, the wheel pinched unexpectedly, and the tool stopped almost immediately, reducing the risk of injury and preventing the grinder from jerking out of my hand. This safety feature impressed me because it engages with maximum force within two seconds or less, a critical factor in preventing accidents. The power loss reset also prevented the grinder from restarting unexpectedly after a power disruption, which gave me peace of mind when working on critical projects.

Ergonomics and Design Considerations

Handling the grinder felt comfortable due to its compact dimensions (12.9″ length, 6.3″ width, 4.9″ height) and weight of around 3.8 pounds. The grip is solid, and the included side handle can be attached on either side, accommodating both right- and left-handed users. The slide switch is easy to operate but requires deliberate action to avoid accidental starts, which I appreciated.

The classic style and brushed finish give it a professional look without unnecessary bulk. However, I noticed that the grinder can feel a bit front-heavy during extended use, especially when doing overhead grinding or cutting. My coworker mentioned a slight vibration that became noticeable after prolonged work, although it never reached a level that caused discomfort or loss of control.

Versatility and Included Accessories

This grinder comes with a thoughtfully curated set of accessories: a 4.5-inch Type 27 guard, inner and outer flange, a hex key, and a side handle. These bits make initial setup straightforward and allow for quick adjustments. The Type 27 guard provides decent protection from sparks and debris, which is essential for safety.

The tool itself is compatible with the *20V MAX battery platform**, but keep in mind that the battery isn’t included. I tested it with several DEWALT 20V batteries, and performance remained consistent across the board. The battery-powered nature frees you from cord restrictions, which is excellent for outdoor or remote jobs.

Perks of Using This Angle Grinder

• Brushless motor eliminates brush changes and extends motor life.
• Kickback brake enhances safety by stopping the wheel within two seconds.
• Power loss reset prevents accidental restarts after power outages.

These standout features make this angle grinder a reliable choice for both professionals and hobbyists who prioritize safety and longevity in their tools.

Drawbacks to Keep in Mind

• The grinder’s weight and front-heavy balance can cause some fatigue during long sessions.
• Slight vibrations become more noticeable after extended use.
• Battery not included, so initial investment may be higher if you don’t already own compatible batteries.
• The slide switch, while secure, can feel a bit stiff to toggle quickly in some situations.

These limitations might not be deal-breakers for everyone, but they are worth considering depending on your specific use case.

Competitive Options in the Market

Looking at similar cordless angle grinders, the DEWALT DCG405B competes directly with models like the Makita XAG04Z and Milwaukee M18 Fuel series. The Makita offers slightly quieter operation and ergonomic design that some users find more comfortable for extended use. However, it lacks the kickback brake feature, which DEWALT implements impressively.

Milwaukee’s grinder boasts longer battery life and a more robust vibration control system, but it’s also heavier and often priced higher. In contrast, the DEWALT balances power, safety features, and portability better than many rivals. The kickback brake and power loss reset are usually missing in competing models, giving this grinder an edge in user safety.

Price Worthiness Compared to Other Tools

Considering the features packed into this cordless angle grinder, the price-to-quality ratio feels reasonable. You get a brushless motor, advanced safety features, and solid build quality, which together justify the investment. The fact that it’s part of the DEWALT 20V MAX* system means you can share batteries with other DEWALT tools, adding value if you already own compatible products.

If you’re starting fresh, the absence of a battery and charger might bump up initial costs, but the tool itself performs like many pricier competitors. For those who need a portable, powerful grinder with safety at the forefront, this tool is definitely worth considering.

Exploring All the Features and Settings

The slide switch provides a secure on/off mechanism, preventing accidental starts, and the kickback brake activates electronically to stop the wheel during pinch or stall incidents. This grinder accepts 4.5-inch discs, making it versatile for cutting, grinding, and polishing tasks. The side handle is adjustable, allowing for comfortable control from either side, a small but appreciated detail.

A detail I liked was the inclusion of inner and outer flanges and a hex key right in the box, which meant no extra tools were needed to start using it. The grinder’s brushless motor ensures optimal energy efficiency, which paired with a 20V battery, delivers consistent power output until the battery runs low. The tool’s solid rectangular shape and brushed finish give it a sturdy feel and professional aesthetic.

After putting this tool through its paces, it’s clear the DEWALT 20V MAX* XR Angle Grinder with Kickback Brake offers a solid blend of power, safety, and convenience, though some ergonomic quirks and the need to source batteries separately might influence your decision. The safety features alone make it stand out in a crowded category, and its compatibility with the DEWALT battery platform adds flexibility for users already invested in that ecosystem.
