The DEWALT DCG426B 20V Max Variable Speed Die Grinder is a solid choice for both professionals and DIY enthusiasts looking for a reliable tool for grinding tasks. One of its main strengths is the DEWALT-built brushless motor, which offers efficient performance and a long runtime, making it a dependable option for various projects. The variable speed trigger allows users to reach up to 25,000 RPM, providing versatility for different grinding applications.

Ergonomically, the grinder offers multiple handle grasping options and a dual-position rocker switch, which can enhance user comfort and control during operation. This makes it suitable for extended use without causing too much strain on the hands.

On the downside, being a cordless model, it requires batteries that are not included with the purchase, which means you’ll need to invest in those separately if you don’t already own them. The battery dependency can also limit continuous use if you don’t have spares charged and ready. Additionally, some users might find the tool a bit heavier compared to other lightweight alternatives, which could affect maneuverability in tighter spaces. In terms of noise and vibration, while most users report satisfactory performance, die grinders typically produce a significant amount of both, so wearing appropriate safety gear is recommended. The product comes with a 3-year limited warranty, which adds to the value, ensuring peace of mind for users regarding its durability.

The tool includes a spindle lock for easy accessory changes and a slide switch that provides simple on/off control.

Being cordless adds to portability but it doesn’t include a battery, so you’ll need to purchase one separately if you don’t already have Milwaukee 18V batteries. This die grinder is a solid choice for professionals or serious DIYers who need a powerful, portable tool without the hassle of cords.
