Score: 88/100
DeWalt DCS578B
Score: 92/100Rankings

The DeWalt DCS578 is a 60V MAX* brushless cordless 7-1/4-inch circular saw designed to deliver corded-level power with 2456W output. It features an electric brake and a 57-degree bevel capacity, making it a high-performance tool for professional framing. While it offers exceptional power and portability, the lack of included batteries and variable speed control are notable trade-offs.
The Milwaukee 2732-20 is a heavy-duty, brushless cordless circular saw designed for professional framing, delivering power equivalent to a 15A corded saw. Its main trade-off is its significant weight and bulk, which can cause fatigue and reduce maneuverability in tight spaces. It is best suited for professional framers and carpenters who need cordless power rivaling corded tools for all-day jobsite use.
