I assume you are asking about drill bits rather than drills per-se.

If you do mean drills than a pillar drill is good, or you could drill on the lathe.

I use DeWalt bullet tip drill bits rather than centre drilling, but centre drilling gives the drill a good start.

Sharp is good and drilling speed is important too. Too fast and you will overheat the drill bit and crack or melt the material.
