The Bosch GKM18V-20 18V Metal-Cutting Circular Saw is a tough cordless circular saw that was engineered specifically to cut through various metals found on the jobsite such as conduit, Unistrut, steel studs, copper piping and threaded rod. The saw delivers cold- metal cutting while leaving a burr-free edge. It has an integrated chip collector for metal shavings during cutting for faster cleanup on the jobsite. This saw delivers 0-4,250 no-load rpm for an outstanding performance-to-weight ratio. It features an LED light that illuminates the cut line in dark work areas, plus it has an impact-resistant clear window, which aids cutting visibility.
