there are several models of the drill doctor - they work OK, but the older
ones have a problem holding a consistent relief angle - sometimes you get negative relief and the drill doesn't do anything. But, it's a lot cheaper than the $6000 Darex "tom" wrote in message ... not quite "woodturning" but related ... http://tinyurl.com/yl4f8pe or equivalent comments? |

If you have an eye for it, it becomes very easy after a few tries and only requires a bench grinder with a squared up wheel. If you have a bench grinder and wheel dresser try it out a bit before you buy a drill doctor. You may find you don't need it. |

I have a slightly larger model which has a gizmo for setting the drill
correctly in the holder.. Looks like this one you do that on your own. Just works on standard twist drill bits and I think concrete bits.. Haven't sharpened any of the latter, but it's a fast, handy, no-brainer sharpener for twist drills.. Won't work on brad point drills, etc..

I had a cigar box full of dull bits and sharpened the whole lot. It worked well. Will not sharpen brad points, spade bits or Forstners, of course. I wish I had a forstner bit sharpener. -- Gerald Ross Cochran, GA No job around the house is done until you bleed on it. |

I agree with some of the posts.
I have a different model - 3/4" max size - and it turns a rounded tip - not two flats. I can cut cross points - that is great. I saved a chipped 3/4" drill - high quality - and after grinding it I then hand ground the flutes for a undercut from the cutting edge. I do a lot by hand, but preform some extensive jobs with mine.

When I was a kid, I looked closely at a dull bit and closely at a sharp bit. Then I turned on the old man's bench grinder. It took a few tries, but got a real sense of "Aha!" when I finally did it correctly. If it's a tiny drill, I use wet sandpaper stuck to glass. -j |
