Good luck with the drill doctor. I got one of the earlier versions and had a hard time getting a good drill bit. it looked really good on the cutting edge but the the trailing edge didn't drop enough. I used the DD to get the cutting edge right then I would finish it out by hand. Maybe the newer style has corrected that. Or maybe I just wasn't using it right???
Mr Snappy said the older ones only had two tabs and tend to wobble.
He said the new ones have splines to help guide it. Supposedly these are better.
He's not the type to blow smoke, so we'll find out.
