What is the primary purpose of tooth set in band saws?

The primary purpose of tooth set in band saws is to widen cuts and prevent binding. The tooth set refers to the slight outward bending of the teeth on a saw blade. This design allows the blade to create a kerf, which is the width of the cut made by the blade, that is wider than the blade itself.

The advantage of this wider kerf is that it helps to prevent the saw blade from binding in the material being cut. When a saw blade cuts through material, there is always a potential for the blade to get stuck if it does not have enough clearance. By setting the teeth outward, the band saw can accommodate the width of the saw teeth within the cut, leading to smoother operation and reducing the likelihood of the blade binding or stalling during the cutting process.

This is essential for efficient cutting, as it keeps the cut effective and minimizes wear on the saw blade. Additionally, a properly set tooth configuration also promotes better chip removal, further aiding in the cutting process without the risk of overheating or damaging the material being worked on. Thus, the tooth set is a critical aspect of band saw design for achieving optimal cutting performance.
