The Drill Doctor has a fairy fine diamond grinding wheel. The way it is set up
seems to get a very good centered finish on the bit at the proper angle.

None of these tools tested gave any mention to the most important item in
getting drills sharp.
That is, always dress the grinding wheel so that it is clean and flat,
also, grinding wheels come with many grit selections. Many who try to
sharpen drill bits give no thought to what grit they are using, or what
type of wheel composition they have.
To put a fine cutting edge on the drill you are sharpening, once the
profile is correct at the cutting anvil, the bit should be final finished
at the cutting planes with a fine grit stone in the grinder.at
Last tip. Watch the video again and specifically observe the cutting chips
each drill is making. Notice the drill that cut the fastest produced very
uniform chips... If you sharpen a bit, and it does not give you chips that
look like that bit produced.
Resharpen it, and reshape the cut planes. Look at a sharp bit that cuts
well... remember what those cutting anvils looked like... Make yours look
just like it. You will be glad you did because it will work.

I agree. These PF Farm reviews seem thorough and address several things I
care about. I suppose the guy must make money from the site because it
costs him to do these vids.

Subject: [MBZ] Sharpening drill bits
Thanks for the response on the Harbor Freight drill bits. Kinda what I
expected to hear. I'll plan to use them for wood, plastic, and aluminum. I
have quite a collection of drill bits, mostly high speed steel, which are
now in various stages of dull.
Given that, my next question is about drill bit sharpeners. I have tried a
couple of those several years ago including a Black and Decker. Took too
much time to sharpen them and the results were not satisfactory. I'm
pretty
sure some of that was due to the user's (me) lack of skill. Sharpening by
hand is out of the question for me. I am just a casual user, mostly in
wood,
but I'd like some drill bits that will perform well in the drill press with
metal.
The ad for Drill Doctor seems to suggest that it easy to use and effective.
What has been your experience with that? Is it worth the price? Does the
cutting stone need replacement?
