What are the methods of setting saw bladea for cutting externally and internally?

Setting saw blades involves adjusting the teeth to ensure proper cutting performance. For external cutting, the teeth can be set alternately to the left and right, allowing for a wider kerf and smoother finish. In contrast, for internal cutting, the teeth may be set straight or less aggressively to maintain a smaller kerf and reduce the risk of binding. Proper blade setting is crucial for achieving clean cuts and prolonging blade life.
