Score: 68/100
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 Craftsman V20 Angle Grinder offers a durable build with a cast metal gear housing and a brushless-equivalent motor, making it a reliable choice for the V20 ecosystem. However, its lower RPM and tool-only configuration make it less ideal for heavy-duty continuous use. It is best suited for users already invested in the Craftsman V20 battery system who need a portable, durable grinder.
