Porter-Cable PC750AG 4-inch vs Milwaukee 2880-20 4.5-inch

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 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.
