Anybody have any experience with these twist drill bit sharpeners? I was talking to a machinist at work and he said that he bought one and could not get a good sharpening job. He discovered that after he followed the drill bit instillation procedure, that the bit would not be straight in the chuck. He said that you could move the shank of the drill back and forth, (sideways) through the back side of the chuck. Any Ideas or suggestions?

I have a friend who has one that seems to work fine for him. I have seen one at work not work after many drills. I sharpen by hand on belt sanders, using a drill point gauge to check. For the money I would buy a drill point gauge and learn how to sharpen by hand. Get a new drill, maybe 3/8 or 7/16 and hold the drill point on the belt or stone to see the angle to use on the drill to be sharpened. I use a upward motion. Checking the drill point gage often to check for even length flutes side to side and the proper angle. And you need some "relief", that is the cutting edge needs to be above the heel so it will cut in and drill. If you hold a drill up in front of you vertically and rotate it so a cutting edge is to the right, the left side should be lower by a slight amount, the relief. Thiis doesn't need to be much at all, if you can see it it will probably be enough to allow the drill to cut in. I know Drill doctors seem to work for some, but this is how I do it and I haven't spent $140 or more on something I don't need.

I sharpened by hand for years, though it was one sharpening process I never got a hundred percent. It's one sharpening process I don't think is possibly by hand as unlike every other sharpening procedure, there is a left and a right side that have to be exactly the same for the tool to work at all.

I bought the drill doctor 750 and it was worth every penny...I hate it when some stupid plastic gizmo works as well as this thing does.... :)

I bought the 400 model, could not get the bit to sharpen correctly. Upon investigation, I noticed that the chuck is wedged on both ends. When you tighten the chuch, it squeezes the chuck vains on both ends. This design allows the drill to be moved sideways. A poor design that only a tool and die maker or machinist would notice. This company needs to spend more money on their product then T.V. advertising. The 400 model sells for about $140. You can buy a lot of quality (small) drill bits for what these Drill Doctors cost.

Mine works so well that I have become spoiled using sharp bits. I go crazy when using a freinds shop and all his stuff is dull. If your machine isn't working right it's probably an operator problem because I know at least 3 guys who swear by it! Initial alignment in the bit holder is critical!

I bought one last summer. The video is important to watch, as it highlights some areas that are critical to alignment. I've watched the video at least twice. Easier to appreciate the process by video than reading the instructions. The bits I've done came out fine.

I bought one, I read the instructions and watched the vidio. I sharpened all my bits, they would not drill. Phoned the company, they walked me through the set up and sharpening process but to no avail. They then sent out a replacement and it did the same thing. It will not allow the bit to bit. So I have two units that do nothing. I just replace the small bits and resharpen the bigger ones on the grinder.

I don't understand.What kind of machinist was your friend? What does the cutting end of a drill have to do with shank wobble in the back side of the chuck?

He is a 57 year old Tool and Die maker. He explained to me that if the drill is not held straight in the chuck, it will not be ground true. Makes sense to me, so I haven't bought one. This man has been sharpening drill bits for approximately 40 years, at his age he can't see well enough to free hand sharpen drill bits. Thats why he bought the drill doctor. He called the company and they couldn't explain what was wrong.

I bought one and it works very well and I found it easy to setup and use. Drill bit should not
move when grinding.

Mine works just fine. Drill shouldn't move at all! One REALLY does need to follow the instructions EXACTLY & watch the video.

If that doesn't work call their Hot line.

Reply to GG I misunderstood your statement about wobble in the chuck.Havent seen a Drill doctor so did not know it has a chuck.I thought reference was to apply to using a drill in a drill chuck after sharpening.Sorry

when all else fails read the instrutions. it sounds like youdid not tighten the holder when you put the bit in turn the knob right to tighten when in the setup position before puting it in the grind position
