Blade Pitch (TPI)

The chart below is a basic starting point for choosing teeth per inch (TPI) for variable tooth pitch blades and standard raker set bi-metal blades/HSS blades. However, for exact specifica- tions of bandsaw blades that are correct for your operation, contact the blade manufacturer.

To select the correct blade pitch:

1.Measure the material thickness. This mea- surement is the length of cut taken from where the tooth enters the workpiece, sweeps through, and exits the workpiece.

2.Refer to the "Material Width/Diameter" row of the blade selection chart in Figure 15, and read across to find the workpiece thickness you need to cut.

3.Refer to the "Material Shapes" row and find the shape of the material to be cut.

4.In the applicable row, read across to the right and find the box where the row and column intersect. Listed in the box is the minimum TPI recommended for the variable tooth pitch blades.

5.The "Cutting Speed Rate Recommendation" section of the chart offers guidelines for vari- ous metals, given in feet per minute (FPM). Choose the speed closest to the number shown in the chart.
