Another thumbs up for the Drill Doctor.  I've gotten very good
service from a 750 (came with a 3/32-1/2" and a 1/2-3/4" chuck) I got
ten+ years ago.  I recently spoke to Darex about a broken part on it
and they gave me an offer I didn't refuse on the current model
750X.  All of their Drill Doctor line of machines were completely
redesigned around five years ago; now they are lower and don't look
like tombstones.  The new design has more metal in it, uses a
different cam geometry, has a slower more stable motor, and a
much-improved method for splitting drill points.  The recent versions
of it come with a single chuck that handles 3/32-3/4"
diameters.  Having used both designs, I can say that the new ones are
better overall.

Darex also makes drill sharpening machines that sell for
thousands.  These are not like those machines, but they're based on
similar ideas.  They take a bit of practice but once you're used to
them they perform very well.  They come with a DVD - videos from it
are available at

One of their Drill Doctor line has less versatility for twist drills
but will also sharpen spade bits.  They have a good page on their
website

calling out the differences amongst their machines.

Some years ago they had horrible customer service, at least for the
Drill Doctor line.  They've taken that to heart and fixed it.  I've
been dealing with Harmony Madueno in their C/S dept and cannot speak
highly enough of her.

Yours,
