OPERATION MANUAL
5.2 BLADE INFORMATION
Selecting the right blade requires a knowledge of
the various blade characteristics mentioned below,
the type of material you plan to cut, and the type of
cut you are going to perform.
Blade Length
The blade length is measured by the circumference.
Blade lengths re usually unique to the brand of your
band saw and the distance between wheels. The
chart below displays the blade length for the
model and available blades.
NOTE: “Available Blades” lists the stocked blades
but other sizes and blade teeth are available from
most local saw blade manufacturers

Blade Width
Measured from the back of the blade to the tip of
the blade tooth (the widest point), blade width is of-
ten the first consideration given to blade selection.
Blade width dictates the largest and smallest
curve that can be cut, as well as how accurately it
can cut a straight line.
Curve Cutting:
View the chart in Fig. 5.6 to determine the correct
blade width for curve cutting. Determine the small-
est radius curve that will be cut on the work piece
and use the corresponding blade width. (Fig. 5.6)
Straight Cutting:
Use the largest width blade available. (See specifi-
cations on Page 4 for the maximum width for the
model)
Tooth Style
When selecting blades, another option
to consider is the shape, gullet size, teeth
set and teeth angle—otherwise known as
“Tooth Style.” As shown Fig.5.7
Raker:
Considered to be the standard
because the tooth size and shape are the
same as the tooth gullet.
Skip:
This style is similar to a raker blade
but is missing every other tooth. Skip
toothed blades have a larger gullet, and cut
faster.
Hook:
This teeth type have a positive angle
(downward) allows them to dig into the
material. The gullets are usually rounded
for easier waste removal. Excellent for the
tough demands and ripping thick material.
