I have 2 of them laying around some place. I could never get the bit as shape with one of them then I can by eye so I gave up on the 2 of them. I tried many times and for some reason I could not get a shape bit when I used them

I've had mine for 10+ years and found it VERY handy. Yes, I can sharpen bits by hand if absolutely necessary, but once you get the hang of it (as noted, it's absolutely essential to follow the directions--they're not difficult, but they need to be done consistently for consistent results) I can get my bits MUCH more uniform using the Drill Doctor, and they stay sharper longer. I have the best luck with drills from 1/8" through 1/2" (the limit of my model) but in a pinch I'll sharpen smaller bits with it. My only problem is that whenever I use it with someone else there, the next time they come by they seem to bring a handful of dull bits with them!

I sharpened by hand for years until I was given a Drill Doctor. Those that think they can sharpen by hand and do it accurately and quickly should put their sharpened bits under good magnification with a reticle scale. They likely will find they are not all that accurate at hand sharpening.

The Drill Doctor is a manual version of the more expensive automated sharpeners. I have sharpened many hundreds of bits with the DD and I am still using the first half of the diamond wheel. It is reversable so when it starts to get worn then just flip it over.

I use mine for 3/4 inch and smaller, over 3/4 inch then I sharpen by hand. The DD will produce the movements you would do when hand sharpening except alot faster and more accurate. The key is the mandril that holds the bit has to be able to follow a cam that moves the bit as you rotate the mandril. Don't hold the mandril in a death grip. Hold it lightly with slight pressure towards the DD and rotate. If held tightly, the drill bit and mandril will not "wobble" on the cam and the bit will not cut correctly. The shank end of the bit sticking out of the mandril should follow an oval pattern as the mandril is rotated.

Good simple directions make it easy to use I think its great. Can resharpen a bit in about 20 seconds when I am in middle of drilling and bit gets a little dull.

All I know is my Boss's son was bored one winter about 8 years ago and he sharpened my set of bits on one.

I had to work a long time by hand to get some of them to cut again. No rake angle, the rear of the bit was dragging and they would not cut.

The other mechanic had the same offer and ended up with the same problem. He got the machine and learned how to make it actually put an edge on there at an angle that would cut. I never took the time.

I have one and it's great. For bits over 1/2 inch or for putting new tips on broken bits over 1/4 inch the optional course wheel speeds things up a lot.

I like mine.

While I have sharpened by hand, this does a better job faster.

Like mine since I have figured out how to do it correctly. Got it as Christmas present a couple of years back. Mine will handle up to 1/2 in bit. Also learned to put oil on bit for better cutting and slow the speed down.

Follow the instructions and it will do a good job.

It will make a bit useless if you don't follow the instructions.
