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:

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.

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.

Refer to the "Material Shapes" row and find

the shape and material to be cut.

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.

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.
