Score: 88/100Rankings
The Festool RO 90 DX is a compact, professional-grade multi-mode sander that combines rotary, orbital, and delta sanding in one tool. It excels in versatility and dust extraction but is limited by its corded design and higher weight compared to entry-level models. Ideal for professionals needing precision in tight spaces and aggressive material removal.
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.
