Score: 72/100
DeWalt DWE402
Score: 72/100Rankings

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.

The DEWALT DWE402 is a powerful corded angle grinder featuring a robust 11-amp motor and 11,000 RPM speed. Its main trade-off is the lack of modern safety features like kickback control and soft start. It is best suited for users who prioritize raw power and durability in a corded tool.
