It can only be done during a full moon and after having consumed a minimum of 4 of adult beverages. The proper sharpening procedure is as follows: Through countless experiments and several sacrificial drill bits I have finally determined the proper methodology. It took me and Jethro ( of the Beverly Hillbillies fame) some time and complicated cyphering to figure out the wear pattern and hence the proper way to position the bit to get it sharpened accurately. Now that I'm retired and have a little more time I do use it on occasions. After a while it was more time consuming to use the machine than it was to sharpen the bits by hand, so it went on the shelf. As time went on the plastic housings started to wear and warp. As I said it worked fine for the first few years. I knew it wasn't a high quality machine, but I needed something quickly. Rather than going back to fiddling around hand sharpening the bits I purchased a Drill Doctor 750. It was stolen only a few months after I purchased it. It was a great machine, but unfortunately someone else liked it more than I did. Then I bought a surplus Black Diamond sharpener from the place I worked. Sometimes it took several weeks to get a batch back. Later I started sending them out, but being a small shop I was always at the bottom of the list. I was originally doing them by hand, but it became so time consuming it cut into the time I needed to be making parts. At that time I was sharpening 50 or so bits per month. I bought it back in the early 1990's when I was doing quite a bit of commercial work.

It worked fine for the first 1,000 or so drill bits, but it takes some real finesse to do a goo job on the smaller sizes these days. I have no experience with the Craftsman model, but I have had a Drill Doctor 750 Classic since they came out over 25 years ago.
