Our take on the Milwaukee 2786-22HD M18 FUEL 9" Cut-Off Saw w/ ONE-KEY

The Milwaukee 2786-22HD is a cordless 9-inch cut-off saw built on the M18 FUEL platform. It runs on REDLITHIUM HIGH OUTPUT batteries instead of gas, so it starts instantly, makes no fumes and needs no gas-oil mixing or engine maintenance. Milwaukee says it cuts reinforced concrete, metal and masonry while being up to 50% lighter than gas saws. It suits contractors and remodelers who cut masonry or metal indoors or in spaces where a gas saw is impractical, and it shares batteries with Milwaukee's 200+ M18 tools. ONE-KEY adds wireless tool tracking and management. The trade-off against gas saws is runtime and battery dependence, and against smaller cordless saws it is heavier and more expensive to run.
