Tooth Set
three common tooth sets are standard, wavy,
and raker (see figure 18), 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 lef t 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, and then a 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 set is ideal for most contour cuts.
Tooth Type
the most common tooth types are described
below and illustrated in figure 19.
Standard or Raker: Equally spaced teeth set
a "0" rake angle. recommended for all purpose
use.
Standard (or Raker)
Variable Pitch (VP)
Variable Pitch Positive Rake
Hook (or Claw)
Skip (or Skip Tooth)
figure 19. 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.
