Choosing Blades

Selecting the right blade requires a knowledge
of the various blade characteristics to match the
blade with the particular cutting operation.

A. Kerf: The amount of material removed by the
blade during cutting.
B. Tooth Set: The amount each tooth is bent
left or right along the blade.
C. Gauge: The thickness of the blade.
D. Blade Width: The widest point of the blade
measured from the tip of the tooth to the back
edge of the blade.
E. Tooth Rake: The angle of the tooth face from
a line perpendicular to the length of the blade.
F. Gullet Depth: The distance from the tooth tip
to the bottom of the curved area (gullet).
G. Tooth Pitch: The distance between tooth
tips.
H. Blade Back: The distance between the bot-
tom of the gullet and the back edge of the
blade.
I. TPI: The number of teeth per inch measured
from gullet to gullet.

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. Blades will
vary slightly even in the same length because of
how they are welded. Refer to the Accessories
section later in this manual for blade replace-
ments from Grizzly.
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.
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 width.
• Straight Cutting: Use the largest width
blade that you own. Large blades excel at
cutting straight lines and are less prone to
wander.
