YATO Circular Saw Blade is a disc consisting of teeth which can cut different materials using a spinning motion. They can be fitted to various power saws depending on the material you are looking to cut and the size of your tool. It's important to select the right bore size and diameter to suit your tool, to ensure it fits properly and for personal safety. The number of teeth the disc has helps to determine the speed, type and finish of cut. Fewer teeth will cut faster whereas more teeth give a finer finish.
