With a Bosch cordless circular saw, you can cut beams, planks, and wooden plates to size. Because it works on a battery, you have a lot of freedom of movement. Make sure the battery is fully charged and you won't have to mess around with extension cords. You can buy Bosch circular saws with or without a battery. So if you already have a battery at home, you can use it for your new Bosch circular saw. Make sure your battery is part of the right battery platform and voltage.
