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.
1. Loosen the point
split nut by rotating
the nut
counterclockwise.
2. Rotate the point
split angle adjuster clockwise to increase
the split angle.
3.
Rotate the adjuster counter clockwise to
decrease the split angle.
4. Once split angle adjustment has been
made, rotate the point split nut clockwise
to retain the selected setting and secure
the point split angle adjuster.
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
Pointed Flat
