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 70).

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 71).
Alternate

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.
