In which direction do the teeth on a band saw point?

The teeth on a band saw point downwards. This design is intentional for several practical reasons. When the saw is in operation, the downward-facing teeth cut into the material, pulling the waste material down and away from the blade. This helps to prevent the sawdust from interfering with the cutting process, allowing for a more efficient and cleaner cut. Additionally, this orientation ensures that the blade provides a clear path for cutting, allowing for better visibility of the workpiece.

The upward positioning of teeth, sideways, or outwards would not facilitate effective cutting and could lead to increased friction, less control, and potential safety hazards during operation. Therefore, pointing downwards is the most effective configuration for the teeth on a band saw.
