Cubic Boron Nitride, second only in hardness to Diamond apparently. No wheel dressing ever required, quick as lightning, cool grinding, will do Tungsten Carbide, last for ages (if not forever, depending on the amount of use of course). Not cheap, but cheaper in the long run for high volume users, and much less hassle. I'll find a link to another thread in a minute, and edit this post.
EDIT: Here you go. The poll results speak for themselves, particularly the answer to "Quicker, cooler, cheaper, better".

I use the coarsest wheel i can find. 36 i think. A course wheel will cut faster and cooler than a fine one. On good HSS you will still get a good finish, certainly good enough if you are going to hone your bits.
For drills i prefer a 60, but i have enough grinders to have every stone and wheel i want on one of them. 36 and SiC on one, wire and a grey wheel on one, multitool and polishing spindle on one and then a 60 and a grey wheel on the big 3 phase one. I only bought 2 of them and they seem to have bred.....
