What does 'Teeth Per Inch' refer to in band saw selection?

'Teeth Per Inch' (TPI) is a critical specification in band saw selection that directly refers to the number of teeth present within a one-inch span of the saw blade. The TPI measurement indicates how finely a band saw can cut through materials. A higher TPI means that there are more teeth available to engage with the material, allowing for smoother, more precise cuts and is typically used for cutting thinner materials. Conversely, a lower TPI provides wider spacing for the teeth and is preferable for cutting thicker materials, as it allows for faster cuts but with a rougher finish.

This characteristic is essential for selecting the appropriate band saw blade for specific applications, as it can significantly impact the quality and efficiency of the cutting process. Understanding TPI helps in making informed decisions regarding the right blade for a given material and desired cut quality.
