Craftsman CMCG400B
Score: 68/100Rankings
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.
The Black+Decker BDEG400 is an entry-level corded angle grinder featuring a metal housing and included grinding wheel. It lacks advanced features like overload protection or a brushless motor, which limits its performance for heavy-duty applications. It is best suited for occasional, light-duty home use.
