Score: 88/100Rankings

The DEWALT DCG413B is a highly portable, brushless cordless angle grinder weighing only 0.45kg. Its standout feature is the integrated Kickback Brake, enhancing safety during operation. It is best suited for professionals who need mobility and reduced fatigue without sacrificing safety features.

The Ryobi R18AG-0 is a lightweight, cordless angle grinder designed for users already invested in the Ryobi 18V ecosystem. Its key strength lies in its ergonomic GripZone+ handle and tool-less guard adjustment, which enhance usability. However, the brushed motor and lower RPM make it less suitable for heavy-duty professional tasks compared to brushless models.
