Makita XAG04Z
Score: 85/100Rankings

The Makita XAG04Z is a versatile cordless angle grinder featuring a brushless motor and advanced safety technologies like Bind-Up Control. Its key strength lies in its portability and intelligent motor management, which extends battery life. The lower RPM and need to purchase batteries separately are notable considerations for buyers.

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.
