Sharpening dull countersink combo bits

JonnyKool's picture

I have a question about countersinks.  I've used Fuller bits and countersinks and I've used a Porter Cable set with my Insty-Bit system.  However, I'm having trouble keeping them sharp and getting them sharp after they've dulled.  Does anyone have any suggestions on sharpening them?
