Me and my brother(who is more interested in metalwork) are considering on buying one of these models, but are not sure on which one or even if their any good. just wandering if anone had any ideas or better jigs/ ways to sharpen drill bits. also a note that we are in the uk, so us products only will not be of use.
thanks again.

I’ve used similar tools in a machine shop environment. While I cannot vouch for the DD personally, the mounting jig(collet) is remarkably similar to the units I’ve used. The ones I used produced consistent results, especially on the smaller bits. I’m gonna watch this one…I’ve been considering them too.

For people with shaky hands or poor eyesight it may be useful.
I have a DD somewhere in my stuff my dad bought on sale
at Sears. I have never used it.

Here’s why:

Standard twist drills are shaped for drilling metal, not wood. It
is easy to resharpen them with the same bevel on a grinder,
except the really small ones can be tricky. If I am sharpening
a bit for wood, I almost always regrind it to a cabinet-maker’s
point, which is like a brad point. It is not that hard to do, though
with the small drills it takes finesse.

I too have considered the DD. Like you said, for the price of a couple of drill bit sets one can purchase a DD. I will be watching this for responses from experienced users.

Thank you, for posting a question that I’m sure many have been wanting to ask!!!

I have one of the original Drill Doctors and use it all the time on my metal drilling bits. It works very well of you set the bit properly in the bit holder.

For woodworking I use brad point bits.

I have the base model I bought on clearance for $20, unopened box. Works for twist and masonary bits. I ruined two bits before I actually took the instructions to heart. You have to set the bit in the collet properly, and watch how you do the rotations.

The trick is to use one hand to hold the collet in place after a rotation, which gives you time to reposition the other hand to turn the collet. This keeps the collect positioned all the time. After that, I spent the next 4 hours sharpening around a hundred bits of all sizes that would fit. I don’t throw anything away. I was shocked at the number of masonary bits I had stashed.

The results mostly exceeded my expectations. Most of the bits were sharpened to like new. For me, the base model worked best on 1/4” and up. I got 1/8” bits sharp but I had to be more careful in the setup. I’ve heard the newer and more expensive models will sharpen brad point bits, and I believe cut a brad of some sort onto a twist bit. As they say, your milage may vary.

I have an older model at home and a newer one at work. The one at work I use all the time and have more than paid for it self not replacing bits. Easy to use and quick.

I have a Drill Doctor 400 that has always worked well for me. It came with the 1/8”-1/2” and the 1/2”-3/4” chuck. It only sharpens to 118°, but will also do split points. Meticulous attention to detail is required when chucking the bit. Otherwise, poor results will be attained.

I’ve seen the video for the newest model on YouTube. It will do spade bits, but not brad point bits. Most of the reviews on Amazon say the spade bit feature doesn’t work very well.

StephenW got it right, the newer models will make and sharpen a split point, not brad points. If I had to guess, a lot of the amazon reviews are by folks not taking the time to learn the system. A file and slip stone will sharpen up spade bits, especially if the bit is placed in a jig to make the angle more easier to work from and maintain, same with router bits.

My Drill Dr has paid for itself many times over but a metal worker will need one more than a woodworker. I have the model that sharpens up to 3/4” bits. Small bits are usually inexpensive but when you get over 1/2” they get a lot pricier.

I have one I used for very small drills, but I sharpen most of them by hand. It worked ok. No complaints.

I have the newer model which also does spade bits. I think its great i have used it a lot and it sharpens bits to new condition. I think it works excellent especially on spade bits, i work as a carpenter also so my bits get a lot of use.

I have had one for a long time and have tried many times unsuccessfully to sharpen drill bits with it. I have come to the conclusion that I could perform brain surgery before I could ever sharpen a drill bit. I own more used dull drill bits than anyone…...........
