Blade Selection
Selecting the right blade for the cutting task
requires knowledge about blade characteristics
and cutting priorities (i.e. speed, finish, etc.).

Figure 46. Bandsaw blade components.
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.

Blade Length
Measured by the blade circumference, blade
lengths are specific to each bandsaw. They are
determined by the wheel diameter and distance
between the 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 replacements 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.
Curve Cutting: Use the chart in Figure 47
•
to determine the correct blade for curve cut-
ting. Determine the smallest radius curve that
will be cut on your workpiece and use the
corresponding blade width (refer to Cutting
Curves on Page 45 for more information).
