Adjusting the Split Angle Rotation
Typically the split angle of a drill is 120° - 130°
from the cutting edge. By increasing the rotation
of the split angle, the split portion of the drill
meets the cutting lip at a greater angle, which
will give the drill more strength and durability.
This added split angle creates a pointed profile
at the very center of the drill, producing a self-
centering effect and reduces drill point walking
at the start of a hole.
