Model SB1018

The chart below is a basic starting point for 

choosing teeth per inch (TPI) for variable 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.

1.  Measure the material thickness. This 

measurement is the distance from where 

each tooth enters the workpiece to where it 

exits the workpiece.

2.  Refer to the "Material Width/Diameter" 

row of the blade selection chart in Figure 

28, 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.
