More info.
Found this some place.
"Boring end grain material with a brad point drill with outlining spurs can be a problem because the spurs are not needed.
The spurs drag in end grain.
Modify the drill by grinding the spurs off following the existing back clearance. Then, regrind the cutting edge with a 7 to 15 degree angle from the O.D. of the drill, tilting downwards to the point, again following the existing back clearance. This is called an acme cut.
Now the brad point enters the material followed by the outlining O.D. (where the spurs were), which sizes the hole without dragging."
And...
"Brad Point drills tend to run out (go off line) and burn in end grain because the spurs try to follow the grain.
The Morris Wood Tool End Grain point does not have lips (spurs) and the clearance angle of the main cutting edges is changed slightly. This point bores straight and clean in most woods."
I picked up 3 (3/16" x 6” OAL with 2-1/4” twist) for $25.59 including shipping.
