What characteristic is important when selecting saw blades based on 'Teeth Per Inch'?

When selecting saw blades, "Teeth Per Inch" (TPI) is a critical characteristic because it directly influences the cutting performance and quality of the cut. The spacing and number of teeth on the blade affect how quickly and efficiently the material can be cut.

A higher TPI means that more teeth are engaged in the cutting process, which typically results in a smoother finish and finer cuts. This is particularly beneficial when cutting softer materials or when precision is essential. Conversely, a lower TPI, with fewer teeth, allows for faster cuts and is better suited for thicker materials or rough cuts, as the larger gaps between teeth permit larger chips to be evacuated more easily.

Understanding the implications of different TPI values is essential for achieving the desired cutting results and optimizing the tool's effectiveness for specific materials and applications. Selecting the appropriate TPI based on the project's needs ensures efficiency and the best possible outcome in the cutting process.
