I'm glad you found it legible, as a couple of my keyboard keys haven't been
working reliably, and I keep putting off connecting a spare keyboard.

Since I started using high quality split-point drills in the 1970s, I knew
immediately that I liked using them more than conventionally-ground drills,
but I didn't know why, really.

So I've discovered the various advantages of split-points over the years,
and try to express them to users that understand the specific aspects that
make them.. well, better, faster, easier etc. to use.

The most difficult "point" to get across, I think, is that the split-points
aren't especially difficult to create.
Fairly accurate split-points can be accomplished freehand, although
attempting to create them on small drills (under 1/8") can be frustrating.
I've recommended practicing on larger drills (about 1/4" or larger) while
examining/comparing the practice drill to a factory-ground new split-point
drill's angles. After the facets have been ground on the trailing/back sides
of the flutes first, the cutting faces and edges can be finished in any
style that's preferred.

The splitting facet grinds are acomplished by bringing the back side of each
flute to the face of the grinding wheel at a fairly low angle. With the
drill standing point up, the top of the drill can be angled back to the
grinding wheel.
A small fixture could be fabricated to facilitate positioning for these
steps, which would insure a fairly precise, repeatable angle for the back
side grinds.
The back side grinds could also be done with the drill point down, but
visibility of the point area is zero.

I've mentioned most of the characteristics of split-points in several
previous posts, but generally don't get any responses.
Thanks for mentioning that you get it.

Do you write professionally?
That was a pleasure to read, even though it was On Topic.
