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 Wavy Raker

Figure 18. Bandsaw tooth sets.

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, 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.

-24-

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.
