G0513 Series Bandsaws
-45-
Bimetal Blade: A strip of high-speed tool steel is
precision welded to a flexible carbon blade, then
teeth are ground into the blade to provide good
edge-holding qualities for blades taking a lot of
abuse (see Figure 65).

Tooth Set
Two common tooth sets for wood bandsaw blades
are alternate and raker. Each different type of
tooth set removes material in a different manner,
leaving cuts with different characteristics (see
Figure 66).
Alternate Raker
Figure 66. Common woodcutting bandsaw blade
tooth sets.
Alternate: An all-purpose arrangement where the
teeth are bent evenly left and right of the blade.
Raker: Three teeth in a recurring group—one
bent left, one bent right, and then one that is not
bent. The raker set is ideal for most contour cuts.
Tooth Type
The most common tooth types for wood blades
are shown and described below (see Figure 67).
