The "Drill Doctor" brand actually makes them. Very expensive uni-tasker tools. I have a Drill Doctor and it's OK. I couldn't get the perfect sharpen, but they weren't dull either. Definitely a learning curve. I've since found a professional sharpening service and I now send everything to them. I'll get my entire bit set sharpened several times a year. They do free pickups too. Havn't use the Drill Doctor for years now, which is unfortunate.
