Band saw tooth size is determined by the size and type of material to be cut and the desired finish. Select a tooth per inch (TPI) based on the charts below. Find material dimensions on bottom of chart and move up for appropriate teeth per inch.
To avoid stripping teeth, always have a minimum of three teeth in the work surface How to measure TPI: Measure 1 or 2 inches along the blade from the center of the gullet. Count the number of teeth in that space. This is the TPI. A blade’s TPI may not always be a whole number. In general the following rule applies to choosing the speed of your band saw blade: The harder the material, the slower the speed; conversely, the softer the material, the faster the speed. The faster the speed, the finer the finish produced on the cut surface.
