The Milwaukee 2785-20 M18 FUEL 9-inch Angle Grinder stands out with its impressive power comparable to 15-amp corded models, making it suitable for heavy-duty grinding and cutting tasks. This tool is capable of delivering up to 6,600 RPM, ensuring efficient performance even under load. The large 9-inch disc size enhances its capability to handle substantial materials quickly. Its brushless motor contributes to higher efficiency and longer lifespan, ideal for prolonged use.

The weight and dimensions are relatively standard, ensuring it’s manageable for most users. The handle design, including a dual action trigger, is thoughtfully engineered to prevent accidental activation, adding a layer of safety. The grinder also features tool-free accessory changes and guard adjustments, which simplify the process of switching tasks and enhance user convenience. Constructed with a metal housing and gearing system, it promises durability and robust performance over time.

However, it’s worth noting that this model is tool-only, meaning the battery and charger are sold separately, which could be a potential drawback for some buyers who do not already own compatible Milwaukee batteries. Additionally, the grinder’s size and power might be overkill for casual users or lighter tasks, making it best suited for professionals or those with demanding projects.

The DEWALT Angle Grinder Tool (D28499X) is a powerful option in the 9-inch angle grinder category, boasting a 5.3 HP motor that operates at 6,000 RPM. This makes it suitable for heavy-duty grinding and cutting tasks, especially in metalworking. The grinder's power source is corded electric, ensuring consistent performance without battery interruptions. The 9-inch disc size is ideal for large-scale jobs, allowing for efficient material removal.

At 16.37 pounds, it is on the heavier side, which may cause fatigue during extended use. The rotating rear handle and 5-position side handle are designed to improve ergonomics, providing some flexibility and comfort during operation. Safety features include automatic turn-off brushes to prevent tool damage, and a keyless adjustable guard for quick adjustments without needing extra tools.

Durability is a strong point, with the tool featuring an epoxy-coated field and armature to protect against abrasion from airborne debris. The 2-wire double insulated 'S' jacket rubber cord also enhances its longevity in various climates. On the downside, its weight could be a drawback for those needing to handle the tool for prolonged periods. Additionally, as a corded model, it requires proximity to a power source, which can limit mobility. This grinder is best suited for professional use and heavy-duty applications where power and durability are prioritized over portability and lightweight handling.

The grinder's durability is enhanced by its German engineering, Metabo Longlife Motor, and features like dust protection and auto-stop carbon brushes that prevent motor damage.

Weighing 14.54 pounds, it may be on the heavier side, but this is counterbalanced by the ergonomic design, including a rotating back and side handle that can be set in three positions for optimal control. The tool-free adjustable guard and anti-vibration side handle add to user comfort and safety, making it easier to use for extended periods without hand fatigue. Safety is further addressed with the Metabo S-automatic mechanical safety slip clutch, which reduces the risk of kickback.

However, at 14.54 pounds, it might be cumbersome for some users, especially for prolonged use. The grinder’s build quality and high performance come at a price, making it more suitable for professional users rather than DIY enthusiasts. With a warranty of three years, it promises reliability and peace of mind. This grinder is an excellent choice for professionals who need a powerful, durable, and safe tool for tough jobs.
