What does the term "set" refer to in relation to a saw blade?

The term "set" in relation to a saw blade specifically refers to the lateral offset of the teeth. This feature is essential for the effective cutting of wood and other materials. When teeth are set, they are angled or positioned away from the blade's centerline, which allows for a wider kerf. This is crucial because it prevents the blade from binding in the material being cut and allows for smooth, efficient operation.

If the teeth were not set, the blade would create a narrower kerf, potentially leading to increased friction and a greater risk of the blade getting stuck in the material. The set helps ensure that the sides of the cut are clean and free from obstructions, which is particularly important for achieving accurate and precise cuts.

Understanding the concept of 'set' is vital when choosing the right blade for specific applications, as different materials and types of cuts may require varying amounts of set for optimal performance.
