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
