That link askes for you to click on to give your permission to pass on info to any advertisers they wish. Sorry, but I wouldn't go anywhere near it. I get enough carp as it is.
As for sharpening Forstner bits, I have a pocket DMT diamond whet stone that I bought from Axminster Power Tools about 18 or so years back. It may seem a bit steep, but they are the best in my humble opinion. It gets a fair amount of use and it still works!

For the cheapie Hilka set I have (from screwfix), an auger bit file is quite adequate. Better bits might need something harder I imagine.

I sharpen mine with a diamond hone. Interestingly, I find with some new ones they aren't as sharp as they could be so it's worth sharpening them even if new if you have any doubts as to how they are cutting.
