The scoring saw blades are used for the high-quality cutting of wood composite materials, which are enriched with melamine films, PVC films and laminates. Before the main saw blade cuts into the panel, the scoring saw blade cuts a groove, so that the tooth of the primary saw blade does not tear the lower side of the panel upon the exit. The scoring saw blade groove must be 1–2 mm deep and 0.1–0.2 mm wider than the main rip saw blade. The scoring saw blades have small diameters, and their advantage is that they rotate in the opposite direction than the primary saw blade. The diameter of the saw blades ranges from 70 to 200 mm. They are made of quality steel and hard metal.
