BLADE CHOICE

Selecting the right blade for the job depends on a variety of
factors, such as the 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 choosing 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 measurement 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 and read across to find your 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
charts offers guidelines for various 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.
