Porter-Cable PC750AG 4-inch
Score: 75/100
Craftsman CMCG400B
Score: 68/100Rankings
The Porter-Cable PC750AG is a lightweight, entry-level angle grinder suitable for occasional home use. Its main advantages are its low weight and comfortable soft-grip handle. However, it lacks advanced safety features like soft start or overload protection, limiting its suitability for heavy-duty professional work.
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.
