Selecting the right blade requires a knowledge
of the various blade characteristics to match the
blade with the particular cutting operation.
Blade Length
Measured by the circumference, blade lengths are
usually unique to the brand of your bandsaw and
the distance between wheels. The Model G0568/
G0569 is designed for blades that are 179"–182"
long. Refer to
Page 48 for blade replacements.
Blade Width
Measured from the back of the blade to the tip of
the blade tooth (the widest point), blade width is
often the first consideration given to blade selec-
tion. Blade width dictates the largest and smallest
curve that can be cut, as well as how accurately it
can cut a straight line.
The Model G0568/G0569 can use blades from

to 1

" in width. Always pick the size of blade that
best suits your application.

Curve Cutting: Use the chart in Figure 62 to
determine the correct blade for curve cutting.
Determine the smallest radius curve that will
be cut on your workpiece and use the corre-
sponding blade width.

Straight Cutting: Use the largest width
blade that you own. Narrow blades can cut
tight curves (a small radius) but are not very
good at cutting straight lines because they
naturally wander (blade lead). However, larg-
er blades are much better at cutting straight
lines, but function poorly at cutting small
curves because of their size.
Tooth Style
When selecting blades, another option to con-
sider is the shape, gullet size, teeth set and teeth
angle—otherwise known as “Tooth Style."
Figure
63 shows the three main categories of tooth style:
•
Raker: This style is considered to be the
standard because the tooth size and shape
are the same as the tooth gullet. The teeth
on raker blades usually are very numerous,
have no angle, and produce cuts by scrap-
ing the material; these characteristics result
in very smooth cuts, but do not cut fast and
generate more heat while cutting.
•
Skip: This style is similar to a raker blade
that is missing every other tooth. Because
of the design, skip toothed blades have a
much larger gullet than raker blades, and
therefore, cut faster and generate more heat.
However, these blades also leave a rougher
cut than raker blades.
