Brushless circular saw is a battery operated device powered by a 20-volt battery of the DEWALT system. It features a 4-1/2-inch diameter, single-blade blade, guide bar and dust extraction adapter. This makes it ideal for cutting materials on construction sites, in workshops and at home. The saw is designed to cut at 90-degree and 45-degree angles. Blade replacement is as quick as possible due to the built-in blade storage. Using the DCB205 battery, you can cut up to 369 linear feet of 3/4-inch OSB. The weight of the saw is 6.6 pounds.
