"I have been eyeballing the drill doctor product for some time. Finally I dropped a hint to the wife I would like one of these, not coincidentally around Christmas time!
When I got the unit I immediately watched the dvd that came with it, and I had already seen the infomercial on the unit so I had a good idea how it worked. After watching the dvd a couple times I started playing with it, yes on the kitchen table on Christmas morning. Move that easy bake oven over kids, Dad needs some room to play also!
It took me a few times to get the angles right, but after just a few tries, I was sharpening bits like a pro. My only real difficulty came in trying to sharpen 18" long bits designed for going through walls. They were top heavy in the drill doctors chuck, making keeping the bit angles aligned.
As usual Northern had the best price and I found a rebate on the 750xx, which made it even more inviing to buy a Drill Doctor at this time. The item was ordered late, just 5 days before Christmas, but somehow Northern Tool got it there before the holiday."
