It's my understanding that Makita has other cordless brushless grinders that are even better than these. Would love to try one but I just can't justify it. I do trail cleanup in our national forest & a cordless angle grinder is sometimes the best tool for a job. More on garagejournal.com

If you're already invested in the Dewalt cordless system, I’d recommend checking out the DEWALT FLEXVOLT DCG414B. It's one of the more powerful cordless grinders out there and really close to a corded grinder in terms of performance. For tasks like cutting bricks, sharpening tools, or light metalwork, it handles everything with ease. Also, for more recommendations, you can check out this thread: Recommended Angle Grinders . The FLEXVOLT system is great because it gives you flexibility—you can use the same battery with both 18V and 54V tools. For heavier tasks, the 6Ah or 9Ah FLEXVOLT batteries are definitely worth considering. They provide longer runtime and handle tough jobs much better than the standard 3Ah ones. If you’re cutting through thick bricks or doing a lot of grinding, the bigger batteries will make a noticeable difference. While the DCG414B is more powerful and ideal for bigger DIY projects, the DCG405FN is still a solid choice if you’re looking for something more compact for lighter, quicker tasks. As with most cordless tools, battery life can be a concern for heavier tasks. Having a couple of batteries on hand is a good idea, so you're not stuck waiting for one to charge. If you're planning to do more extended work, consider grabbing an extra FLEXVOLT battery or a fast charger to keep things moving. In short, the DCG414B paired with FLEXVOLT batteries offers excellent performance for DIY use while keeping the convenience of your existing Dewalt ecosystem.. More on reddit.com
