Choosing Blades

and Speeds

Selecting the right blade for the job depends on a variety of factors, such as type of material being cut, hardness of the material, material shape, machine capability, and operator technique.

The chart below is a basic starting point for choos- ing blade type based on teeth per inch (TPI) for variable tooth pitch blades and for standard raker type bi-metal blades/HSS blades. However, for exact specifications of bandsaw blades, contact the blade manufacturer.

To select the correct blade TPI:

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 48 and read across to find the workpiece thickness you need to cut.

3.Refer to the "Material Shapes" row and find the shape and 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 (speed FPM) and meters per minute in parenthesis. Choose the speed closest to the number shown in the chart.
