Drill Doctor.JPG In a post I just read about making a nut to drill shackle bolts was brought up about having a sharp bit. If you get to my age the eye balls aren't as good as they used to be for sharpening the bits.......especially the small ones. At work we had a Drill Doctor, I tried it an didn't really care for it. One day I was over to my brothers and we needed to sharpen some small bits, he got out his Drill Doctor an showed me how to sharpen. After using his I had to have one. If you follow the directions you will get a sharpened bit that does the job. You can buy one for just the small bits or one that will do the larger bits also, plus masonry bits. After owning one I believe that is the way to go. I bought mine new off Ebay for a decent price. This picture came off Drilldoctor.com.

When I was in the Army I had weekends off, so for a few months I worked weekends making gooseneck trailers. The boss showed me how to sharpen drill bits, and he was good. Glad he showed me, because a few years later I bought a Drill Doctor, but returned it. I liked sharpening them by hand better. Small bits can be tough, and I thought about mounting a magnifying glass over the grind stone.

Tom, I was a machinist in the Navy and went to California to Machine Repairman school. We learned how to sharpen drills on a pedestal grinder. I have always sharpened them this way and still do the larger ones. It's the small size I have trouble with. If you ever do mount a magnifying glass over your grinder, please post a picture. I enjoy your posts here. Thanks

BTW, for small bits I use my Dremel with a grinding stone and work under my magnifying clamp on light.

Years ago I bought a Craftsman bit sharpener, and it mounts in front of a grinding wheel. It holds the bit at an adjustable angle and depth, then you swing the bit through an arc to grind the proper angle. I like it, as it grinds both flutes to the same depth. It's especially good for larger bits, like when my 1/2" bit grabbed and broke a large chip out of it.

I have a Drill Doctor and it does good on the smaller bits but the larger bits don't fit in it and have to be done by hand.
I have bits up to 1-1/4" inch.

Funny you bring it up, I was using mine yesterday to get through some work-hardened self-tappers in my Tudor's rear seat pan.
Tried hand-sharpening time and again, never got on with it. I just accept there's some things I simply can't do.
I bought the XP model, does 3-13mm, (⅛" - ½") or up to 19mm (¾") with a larger chuck. Best $300 I ever spent.
