DeWalt DWE402
Score: 72/100
Black+Decker BDEG400
Score: 65/100Rankings

The DEWALT DWE402 is a powerful corded angle grinder featuring a robust 11-amp motor and 11,000 RPM speed. Its main trade-off is the lack of modern safety features like kickback control and soft start. It is best suited for users who prioritize raw power and durability in a corded tool.

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.
