You can use a Bosch Professional cordless circular saw for long work pieces. You can easily and quickly saw straight lines in wood, sheet material, or plastic. For example, you can cut planks or saw large sheets to size. The battery allows you to work anywhere without being restricted by a cord. Bosch Blue circular saws are part of the Bosch Professional 18V System battery platform. You can also use a battery from this platform on other Bosch Professional (garden) tools with the same voltage. This allows you to perform multiple jobs in a row.
