Bought one when they first came out years ago. Seemed to work OK on smaller bits, but not so well on anything over 1/4". Haven't used it in years.

I have two for my crews to use and they work like a champ. Worth every penny spent.

I love mine

[10-x]

Sharpen mine by hand with a gauge, faster and better results. Once you learn how to do it, it's easy.

Im going to go with the two fellers that are not to impressed with it. I can do pretty well off hand but I also have a Sterling that does a fine job.

Not sure why everyone loves them so much I was not very impressed with mine and I tried everything to make it work right, does ok I guess but I have a small dedicated grinder with a guide and using a gauge I get as good or better results by hand and it's a lot quicker and easier.

I ended up making my bits worse with mine lol! Never could get it to work in my favor.

[ddaniel1]

Couldn't get mine to work either, its on my list to give it another try, so many people love them so I figure I must be doing something wrong.

Glad to see I'm not alone tho! ^^^^^^^

Love mine. Sharpened 100s of harbor freight bits before sharpening my snap on bits even did my 5/8 & 3/4 bits have the pro model. Nothing but good results. Still haven't changed the wheel.

Got one as a Christmas gift. Piece of junk! I have always sharpened by hand and by eye.

[TreeKiller]

I have the basic model works great for me. But i think that if you have a dedicated grinder with the proper tool guide and rest it would be faster. I think the one with the ability to but a back grind or what ever you call it that reduces the drag on the back side of the bit would be better than the basic tool.

i just finished drilling nine holes in a fairly thick steel top to mount some equipment in my shop. I used my Drill Doctor several times to freshen up my bits. I don't doubt that someone with experience can do a great job by eye and by hand. I simply cannot. I have tried and I seem to be challenged in that area. Without my Drill Doctor I'd be in a heap of trouble drilling holes in steel or wood either for that matter. I recommend someone who cannot sharpen by hand to give one a try.

My brother has one at his farm and loves it. Unless Dad or I stop by then he asks us to sharpen his bits for him. Machine shop where I started out ( age 15) had a contarct to sharpen bits for a plastics / fiberglass plant down the road. They brought them in in 5 gallon buckets 1/4" - 2" 4 flutes were the norm. Alot of practice there. After 35 years being a journeyman tool and die maker I just use a pedistal grinder by hand. Dad after 40 years does the same. All it takes is practice and a good teacher. The big thing to the back rake on drills over 3/8 is doing it so it thins the web also. In one interview I was ask to sharpen a drill bit. It was one of the "basic skills" we were taught first off.

Love mine. Have had it for 12+ years. It paid for itself on the first job I had it on and is still going strong. I sharpen all the sizes up to 3/4" (you really have to stay ahead on the larger sizes - otherwise they take a long time to resharpen). Wouldn't be without it.

Works good for me. I sharpen solid carbide drills on it on a regular basis. Have the model that does up to 3/4". I can sharpen them on a bench grinder no problem but the consistancy is still better with the DD.

[oldred]

1/4" - 2" 4 flutes were the norm.

4 flute drill bits? I have seen 4 flute auger drills for wood but didn't know there was a 4 flute drill for metal, I bet those things are a real bear to sharpen and get all the flutes cutting.
