Milwaukee 2880-20 4.5-inch
Score: 82/100Rankings

The Milwaukee 2880-20 is a versatile cordless angle grinder featuring a brushless motor and RAPIDSTOP brake technology for enhanced safety and performance. Its key advantage is the mobility provided by the M18 battery system, making it ideal for job sites without power outlets. However, the lack of included batteries and the smaller disc size are notable trade-offs for heavy-duty users.

The DEWALT DCG412B is a lightweight, cordless 4-1/2 inch angle grinder designed for portability and ease of use. It features tool-free adjustments and a 2-finger trigger, making it convenient for cutting and grinding tasks. However, it lacks advanced safety features like kickback control and requires a separate battery purchase.
