Scoring Blade
The scoring blade rotates in the opposite direction
from the main blade and makes a shallow cut into
the workpiece surface. This prevents workpiece
tearout.
The scoring blade included with the Model G0820
has wedge-shaped teeth that narrow at the top,
as shown in
Figure 86. With this style of scoring
blade, the kerf thickness is adjusted by changing
the height of the scoring blade. Raising the scor-
ing blade higher increases the kerf thickness.
