The Model G9744Z2 uses 121

" x 1" bandsaw
blades.
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 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 19 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 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.
