Woody what's different about the end grain bit? Where did you get it?

[numbskull]

They are brad point bits with no spurs. Fuller drill (and presumably Morris Tools) will grind them on any size drill you want. It is what the drill companies recommend for end grain.

Check out the step drills while you are at it. Expensive but very useful for enlarging through holes concentrically to fit belly weights.

Never a problem with brad points? Standard bits wander too much...much more than brad point bits.

I've had problems with both. I use a lathe, but have used a drill press also and have messed up many a blank. It's all trial and error. Gotta love it! I use a short bit in the lathe and make the connection with a 10" bit in my hand drill. When using the hand drill I've found that going slow and backing out is the key, especially with hard woods (Maple, Mahogany).

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.
