How do you sharpen your Forstner bits ?

Cap’n Eddie posted a video on touching up Forstner bits several years ago. His stuff is pretty clear and I hope this helps you.

-- People say I hammer like lightning. It's not that I'm fast -- it's that I never hit the same place twice!

Lots of patience, and watching Capt Eddy’s video!

Those also work well to quickly touch up a lathe tool in between sharpening and round ones for the flutes on gouges.

I watch Mr Castleton quite a bit and have gotten many useful tips from him.
I just watched him with the Forstner Bit…thanks

The diamond hones are fine and I use them. However my favorite way to sharpen Forstner bits and other small cutting tools is to use a diamond disk in a Dremel tool. http://www.harborfreight.com/catalogsearch/result?q=diamond+disk
The disks last quite a long time and occasionally they are on sale. That’s when I buy a bunch. The diamond disks do the job very nicely and quickly.
