Blade Information - Grizzly G0457 Owner's Manual

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
Measured by the circumference, blade lengths
are usually unique to the brand of your bandsaw
and the distance between wheels. the Model
g0457 is designed for blades that are 106" long.
refer to the current grizzly catalog for prices and
ordering information.
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 g0457 can use blades from
in width. Always pick the size of blade that best
suits your application.
curve cutting: Use the chart in figure 42 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.

blade that you own. the Model g0457 will
accept blades up to
can cut tight curves (a small radius) but
are not very good at cutting straight lines
because they naturally wander (blade lead).
however, larger 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 43 shows the three main categories of
tooth style:

figure 43. raker, Skip & hook tooth styles.
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.
