The most common tooth types are described as
follows, and illustrated in
Figure 26.

Standard or Raker: Equally spaced teeth set at
a "0" rake angle. Recommended for all purpose
use.
Variable Pitch (VP): Varying gullet depth and
tooth spacing, a "0" rake angle, excellent chip
removing capacity, and smooth cutting.
Selecting the right blade for the cut requires a
knowledge of various blade characteristics.
A. Kerf: The amount of material removed by the
blade during cutting.
B. Tooth Set: The amount each tooth is bent
left or right from the blade.
C. Gauge: The thickness of the blade.
D. Blade Width: The widest point of the blade
measured from the tip of the tooth to the back
edge of the blade.
E. Tooth Rake: The angle of the tooth face from
a line perpendicular to the length of the blade.

F. Gullet Depth: The distance from the tooth tip
to the bottom of the curved area (gullet).
G. Tooth Pitch: The distance between tooth
tips.
H. Blade Back: The distance between the bot-
tom of the gullet and the back edge of the
blade.
I. Blade Pitch or TPI: The number of teeth per
inch measured from gullet to gullet.
13. Puts on safety glasses and respirator.
14. Opens coolant valves (refer to Using Coolant
System on Page 39).
15. Starts blade movement, and allows machine
to complete cut(s).
16. Inspects chips and adjusts blade feed rate as
needed (refer to
Chip Inspection Chart on
Page 34).
17. When finished, turns machine OFF.
