What does "tooth set" refer to in the context of band saw blades?

Tooth set refers specifically to the degree to which the teeth of a band saw blade are bent outward from the body of the blade. This design is crucial for creating a wider kerf, which is the groove cut by the saw. The outward bending of the teeth allows for the removal of material and helps prevent tooth binding during cutting, as it provides space for the material being cut. This characteristic is essential for the blade’s performance, particularly when making cuts in various materials, as it can enhance cutting efficiency and help manage waste.

The other choices focus on different aspects of the teeth that do not specifically define tooth set. For instance, the degree of teeth spacing relates to how far apart the teeth are from each other but does not address their angle or bend. The angle of the teeth influences cutting ability and blade performance, while the overall shape pertains to the design profile of the teeth, neither of which directly represents the concept of "tooth set." Understanding tooth set is important for selecting the appropriate saw blade for specific cutting applications and materials.
