There are several types of tooth configurations for circular saw blades, including Alternate top bevels (ATB), Triple-chip grind (TCG), flat teeth (FZ), etc. It is mainly based on the character of raw materials to be processed. ATB teeth are done for slitting and cross-cutting all kinds of soft, hard, and particleboard, it is equipped with anti-rebound protection teeth that are suitable for longitudinal cutting many types of materials. ATB saw blades with negative front angles are usually used for sawing veneers due to their sharp teeth and extraordinary quality.
Flat teeth are mainly applicated in processing common wood. The cost of this type is low, but the cutting edge is rough. A combination of trapezoidal teeth and flat teeth also can obtain higher sawing quality without grooving the saw blade, so veneer cracking will not occur during processing. It is fit for processing various double-faced wood-based panels.
