I have d drill doctor. Not very impressed with it. In the beginning, it did a reasonable job on dull bits. After a while, it became less and less accurate. Most of the problem lies with the chuck that you use to hold the drill bit that you are sharpening. It seems to start getting really sensitive to the dust from sharpening. Then it needs frequent cleaning. Overall, I did not like it as much as I thought I would. I also find that it is not good for "custom" sharpening. I hand sharpen according to what I am drilling. Brass, copper, and even Aluminum take less relief than steel and cast. I use a high relief for steel and castings. Then there are special tips for sheet metal. For drilling out broken bolts and studs, I reverse sharpen my bits. Many times, a reverse bit will unthread a broken off bolt. Also, I thought the Drill Doctor was a bit on the expensive side. Mine was around $125. I should have saved the money for a replacement stone for my grinder.
