Score: 88/100Rankings

The DEWALT DCW210B is a powerful cordless orbital sander featuring a brushless motor and variable speed control for versatile sanding tasks. Its main trade-off is the tool-only format, which necessitates owning compatible 20V batteries. It is best suited for DIYers and professionals already invested in the DEWALT 20V ecosystem.
The Milwaukee Tool M12 3-Inch Random Orbital Sander is a compact, brushless 12V tool designed for fine finishing tasks, featuring a 3/32-inch orbit to minimize swirl marks. It offers variable speed control and includes dual vacuum ports for efficient dust extraction, making it ideal for automotive and woodworking applications. However, it is less suited for heavy stock removal or ultra-detailed work on tiny spots.
