<p>I sold my Drill Dr. on Ebay for what I gave for it and I just
sharpen bits by hand. A magnifying lens headgear is a lot of help
when sharpening. It lets me see how I have ground the sharp edge
and the relief angle as I call it. The angle that the bit is
ground behind the cutting edge is what determines how much is cut
on each turn of the bit. Understanding the angles seemed to help
me to sharpen by hand. Being able to really see the edge of the
bit with the magnifier made a world of difference. <br>

<div>Hey Cecil,</div>

</div>
<div>When I first got the drill doctor I could not get results I
expected. It was close but still not what I expected. I kept
thinking it was the machine but after several friends continue
to swear by them I finally decided it was the operator :-)</div>

</div>
<div>I went to their web site and viewed several of their videos
and realized there was a small trick I was missing. I wish I
could remember what it was. I think it’s the orientation of the
bit during that initial set up when you set the depth in the
chuck. Whatever it was I remember being pretty easy on myself
because the manual was not clear on it.</div>
<div><br>
</div>
<div>Anyways maybe go back through some of their videos and some
of the other folks‘ YouTube stuff and make sure you’re doing
everything. I wasn’t and am much happier now.</div>

<p><...snip...> I have had a couple of the Drill
Doctors, but gave up on trying to get them to sharpen a
bit correctly. I just use my eyeball... After 50 years,
it is not too hard. I do have a drill grinder for bits
