If there are any advantages of using ordinary conventionally-ground drills
over split-point drills, I'd very much appreciate hearing about them.

If I'm doing a lot of drilling in difficult materials I have found
that not splitting the points makes the drill last longer.

Hey Brian. *Not to worry Buddy! *AFAIK, the M3 and M5 differ only in that
the M5 includes a Baldor
grinder, web-thinning attachment, and a point splitter. *Otherwise, I
think they are basically the
same. *I have owned the Glendo version of the M3 for many years and have
been very pleased with it.
It resides in front of my old 1/2" Craftsman bench grinder. *Right now I'm
moving the grinder, the
M3, and Glendo's protractor table onto a new 1/2" steel plate. *I do most
tool bit sharpening with
the old Craftsman. *A new Glendo Accu-Finish diamond grinder is reserved
for carbide tools. *It sits
under a microscope.

PS: *Re. all the chatter about point splitting: *I can't imagine why
anyone with machine tools would
be concerned with point splitting. *Web thinning, a distant "maybe".
