Ryobi R18AG
Score: 72/100
Craftsman CMCG400B
Score: 68/100Rankings
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 Craftsman V20 Angle Grinder offers a durable build with a cast metal gear housing and a brushless-equivalent motor, making it a reliable choice for the V20 ecosystem. However, its lower RPM and tool-only configuration make it less ideal for heavy-duty continuous use. It is best suited for users already invested in the Craftsman V20 battery system who need a portable, durable grinder.
