I sharpen mine on a regular grinding stone, on something like this, no attachments.

Me to, But i am getting so freakin blind it is getting tougher, At Rays, it was so dark in his shop, had to re-do several. We were installing the new rail tie down system on my car trailer, lots of holes thru Diamond plate. Had to sharpen several bits, and of course I broke a couple.
