Teeth-per-inch on a blade is chosen based on material hardness and how the cut should feel. For hard, tough metals like annealed high carbon steel and high speed steel, a coarser blade with about six to eight teeth per inch is ideal. The larger teeth take bigger bites and leave bigger chips, which helps prevent binding and reduces wear on the teeth while still cutting efficiently through the metal. Blades with fewer teeth per inch bite even larger but can stress hard metals, while blades with more teeth per inch are better for softer or thinner work where a smoother finish is desired. That’s why six to eight teeth per inch is the best match for annealed high carbon steel and high speed steel.
