You can saw curves and straight lines in wood, plastic, and metal with a Bosch Professional cordless jigsaw. The machine works on a battery, so you're not bothered by a cord. Keep the cutting depth in mind, because it determines how thick the material you saw can be. Bosch Blue jigsaws are part of the Bosch Professional 18V System battery platform. You can use a battery from this platform on other Bosch Professional (garden) tools with the same voltage.
