The design is fairly compact with dimensions of 12.2 inches in length, 4.7 inches in width, and 6 inches in height, and it weighs 3.75 pounds, making it relatively lightweight and easy to handle. Ergonomically, it includes features like a two-stage trigger to reduce the risk of accidental activation and improve user safety. Safety features are a strong point of this model, with a brake that stops the wheel in 2 seconds or less and a kickback brake that engages in the event of a pinch or stall, reducing potential hazards. Additionally, the E-Switch Protection ensures that the tool won't unexpectedly restart after a power interruption.

One downside is the absence of included batteries, which could be inconvenient for users without compatible ones. The build quality is robust, using plastic and metal materials, and it comes with a 3-year limited warranty.

With an 18-volt battery power source and a maximum rotational speed of 8500 RPM, it's built to deliver strong performance. The 4-1/2 and 5-inch disc compatibility means it’s versatile for various grinding tasks. A significant strength is its battery life, especially considering it's compatible with all M18 batteries, making it convenient for users already invested in Milwaukee's M18 system.

Additionally, the anti-vibration side handle and electronic clutch for kickback protection are notable safety and comfort features, enhancing user comfort and safety during prolonged use. However, it is important to note that the tool does not come with the battery, which is an added expense for new users. At 4.99 pounds, it strikes a good balance between being lightweight and sturdy, but some users might still find it slightly heavy for extended use.

The overload protection feature aims to maximize motor life, making it durable and reliable.

The grinder accommodates disc sizes from 4-1/2 inches to 5 inches, providing flexibility for different tasks.

Additionally, the E-Switch Protection adds another layer of safety by requiring a manual restart after power interruptions.

Despite the high-performance features, the grinder remains relatively lightweight at 1 pound, which should help reduce fatigue during extended use. The ergonomic design further enhances user comfort, though some might find the paddle switch less convenient compared to traditional trigger switches. This model doesn't include the batteries, which could make it less appealing for those new to the DEWALT battery system. In addition, while its power and safety features are commendable, the added cost of acquiring FLEXVOLT batteries might be a consideration for budget-conscious users.
