Tooth Set
three common tooth sets are standard, wavy,
and raker (see
figure 30
), each removing mate-
rial in a different manner to make the kerf in the
workpiece.
Alternate:
An all-purpose arrangement of bend-
ing the teeth evenly left and right of the blade.
generally used for milder metals.
Wavy:
generally three or more teeth in a group
that are bent one way, followed by a non-set
tooth, then another group bent the other way.
recommended for straight cuts in thin metals or
thin-wall tubing.
Raker:
three teeth in a recurring group—one
bent left, next one bent right, and then a non-set
tooth.
the raker is ideal for most contour cuts.

Bandsaw blade tooth types.
Variable pitch (Vp):
Varying gullet depth and
tooth spacing, a "0" rake angle, excellent chip
removing capacity, and smooth cutting.
Variable pitch with positive Rake:
Varying gul-
let depth and tooth spacing, a positive rake angle,
better chip formation, and aggressive cutting.
hook or Claw:
Wide gullets (round or flat), equal-
ly spaced teeth, positive rake angle, and fast cut
with good surface finish.
Skip or Skip Tooth:
Wide, flat gullets, a "0" rake
angle, equally spaced teeth, and recommended
for non-ferrous materials.
