What are the cutouts between the blade teeth called that allow material to be ejected during cutting?

The correct answer is that the cutouts between the blade teeth are called a gullet. Gullets are crucial features of cutting tools, particularly in saw blades and similar implements. They serve as reservoirs that collect and eject material that is being cut. This allows for more efficient cutting by providing space for chips or shavings to exit the cutting area instead of clogging the blade, which could lead to overheating or breakage.

The other terms mentioned provide context that distinguishes them from the concept of a gullet. For example, kerf refers to the width of the cut made by the blade itself, indicating how much material is removed during the cutting process. Tooth pitch outlines the distance between the individual teeth on the blade, affecting how many teeth are in contact with the material at any given time. Set, on the other hand, describes the outward bend of the teeth of a saw blade, which helps with chip removal and prevents binding of the blade in the cut. Understanding these terms enhances comprehension of how cutting tools operate effectively in aerospace manufacturing and assembly contexts.
