Who Should Buy This
This DEWALT 20V MAX* Angle Grinder is perfect for DIY enthusiasts and professionals who need a reliable, cordless tool. If you work on metal, masonry, or construction projects, this grinder will make your job easier. Its brushless motor offers more power and longer runtime. The paddle switch and kickback brake add safety, making it great for both beginners and experienced users.
If you only do very light or occasional grinding, this tool might be more than you need. Also, since this is a “tool only” product, you need to have a DEWALT 20V battery and charger already.

Our Testing Experience
First Impressions
When I first took the DEWALT 20V MAX* Angle Grinder out of the box, I was impressed by how solid and well-built it felt despite being cordless. The size was just right for my hands—compact at 6.0 x 4.7 x 12.2 inches, making it easy to hold and control. I charged the battery and got straight to work, curious to see how the brushless motor would perform without the usual noise and maintenance of brushes.
Daily Use
Using this grinder every day on different metal projects quickly showed me how convenient the paddle switch is. It felt natural to turn on and off without fumbling around. During a tough job where the wheel got pinched a couple of times, the kickback brake kicked in immediately. It stopped the wheel in less than two seconds, which honestly made me feel safer and more confident while working. It really helped reduce the jerky movements that usually come with a stuck grinder.
Key Features in Action
The brushless motor stood out the most for me. I noticed the grinder stayed cooler and ran smoother than other models I’ve used in the past. No brush changes needed meant less downtime and hassle. The kickback brake was a game changer—once it sensed any bind-up, it stopped the wheel fast and shut the tool off, which gave me peace of mind. This feature alone makes it worth the investment if you’re worried about safety.
Long-Term Performance
After several weeks of regular use, the DEWALT angle grinder kept performing like new. The battery life held up well, and I didn’t experience any drop in power or speed. The brake system remained reliable every time I needed it, and the tool’s overall durability impressed me. It’s clear this grinder is built to last and handle heavy-duty tasks without wearing out quickly.
