Score: 88/100Rankings

The DEWALT DCG408B is a lightweight, cordless 4.5-inch angle grinder featuring a brushless motor and advanced safety features like a kickback brake. Its portability and modern features make it ideal for on-site work, though it requires a separate battery and has lower power than corded models. It is best suited for professionals who value mobility and safety.

The Craftsman CMEG100 is a lightweight, corded angle grinder ideal for light-duty tasks like polishing and thin metal cutting. Its high RPM and low weight are advantages, but the lack of overload protection and lower power output make it less suitable for heavy industrial use.
