This is a video on the drill doctor 750 X. I've looked at these for many a year and put off buying one because of the cost, but the new drill bits that you can buy nowadays not as good as they used to be.
So now I have the drill doctor I can sharpen my drill bits as you always find your drill bits to be blunt when you need the most.
If you can warrant the cost of buying this item I can fully recommend it.
