Ryobi R18AG
Score: 72/100
Milwaukee 2880-20 4.5-inch
Score: 82/100Rankings
The Milwaukee 2880-20 is a versatile cordless angle grinder featuring a brushless motor and RAPIDSTOP brake technology for enhanced safety and performance. Its key advantage is the mobility provided by the M18 battery system, making it ideal for job sites without power outlets. However, the lack of included batteries and the smaller disc size are notable trade-offs for heavy-duty users.
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.
