808 - the June/July 2003 issue of Wood magazine has an informative article on Forstner bits. It also shows how to sharpen the standard type. It says:
"Forget sharpening the rim. The cutting edge of the rim has to stay on the same plane, and that's nearly impossible without special machinery.
Focus on the lifter. Use a small, fine file, a thin stone, or a strip sander. Sharpen the flat face of the lifter, then remove the burr on the cutting edge with a stone. Go easy, don't abrade away too much of the lifter, especially near the rim. Forstner bits have a slight back taper, and if you sharpen too much, you can change the geometry of the bit, which may cause it to overheat.";)
