A Higher TPI Saw Blade Makes Smoother Cuts

The Importance of Tooth Per Inch (TPI) on Saw Blades

Teeth per Inch (TPI) Definition: TPI refers to the number of teeth that are present on the blade over a length of one inch. It is a crucial factor that determines the quality of the cut made by a saw blade.

Effect of TPI on Cut Finish Quality

Blades with a higher TPI create finer, cleaner cuts. The increased number of teeth allows for a smoother cutting action, resulting in a polished finish on the material being cut. This is particularly beneficial when working with delicate materials where precision and a high-quality finish are desired.

On the other hand, lower TPI blades are designed for faster, rougher cuts. They are commonly used for cutting softwoods or materials where a smooth finish is not a top priority.

Comparison to Blade Design Efficiency

While a three-blade design is noted as the most efficient in terms of safety and cutting speed, it is important to differentiate this from TPI. The efficiency of a blade in terms of the number of blades may impact safety and cutting speed, but TPI specifically refers to the smoothness of the cut produced by the saw blade.

Therefore, when selecting a saw blade for a particular task, it is essential to consider both the blade design and the TPI to achieve the desired cutting results. A higher TPI blade is ideal for intricate cuts that require a smooth finish, while lower TPI blades are more suitable for rapid, rough cuts.
