The answer to this question depends on three factors: the motor power, the characteristics of a blade, and the density of wood (it is easier to work with soft types). The more powerful your device is, the deeper the cut it can make. Also, this indicator is influenced by the blade length and the number of teeth per inch (the fewer there are, the thicker the material you can cut). To roughly determine the thickness of wood your saw can cut, subtract one inch from the length of your blade. You can also process thicker materials, but it will have to be done in several steps.
