Contractors wanted a fast and portable metal cutting solution. Makita answered with the 18V LXT Lithium-Ion Cordless 5-3/8" Metal Cutting Saw (BCS550).
The BCS550 is a jobsite favorite for a range of metal cutting applications -- without the cord. It's part of Makita's 40+ tool line-up powered by ONE 18V Lithium-Ion battery.
