The Milwaukee M18 Fuel Metal Cutting Circular Saw is a compact, cordless brushless saw designed for fast, burr-free cuts in ferrous metals like EMT conduit and sheet metal.

The tool is optimized for electricians and HVAC technicians needing portable, high-volume cutting capabilities in tight spaces.
The Milwaukee 2732-20 is a heavy-duty, brushless cordless circular saw designed for professional framing, delivering power equivalent to a 15A corded saw.

It is best suited for professional framers and carpenters who need cordless power rivaling corded tools for all-day jobsite use.
