Blade Pitch (TPI)

The chart below is a basic starting point when choosing blade type based on teeth per inch (TPI) for variable tooth pitch blades and standard raker set bi-metal blades/HSS blades. However, for exact specifications 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 left-most column of the cutting speed recommendation chart in Figure 32, and read down to find the workpiece thick- ness you need to cut.

3.In the applicable row, read across to the right and find the column of the material you are cutting. Listed in the box is the minimum TPI recommended for the variable tooth pitch blades.

4.Read towards the bottom of the column to the "F.P.M." row. This figure is the recommended feet per minute blade speed for the material you are cutting. Refer to the speed chart on the machine or Changing Speeds, Page 30, to adjust the Model G0659 to the closest appropriate speed.
