The main purpose of a gullet is to provide clearance for the material being removed. The design of the gullet must be done keeping in mind such factors as material being cut, type of cut (rip or crosscut and smooth or rough), speed of the cut, type of tooth design and pitch or hook angle of the teeth. For example, a Rip saw blade is designed to cut very quickly along the grain of the wood. It has fewer teeth and a large gullet to aid in the removal of sawdust. By contrast, a Crosscut blade will have a smoother, slower cut against the grain, therefore having more teeth and a smaller gullet design. The major issue to consider in design is to have no sharp or square corners as they will lend themselves as a natural stress or fault line in the saw blade. The gullet is a relief area cut in front of the tooth which provides a temporary place to store the material cut away by the tooth on each revolution of the blade.
