Score: 72/100
Makita XAG04Z
Score: 85/100Rankings

The Makita XAG04Z is a versatile cordless angle grinder featuring a brushless motor and advanced safety technologies like Bind-Up Control. Its key strength lies in its portability and intelligent motor management, which extends battery life. The lower RPM and need to purchase batteries separately are notable considerations for buyers.

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.
