There is also a V-Block with a series of drill holes that you just lay
on the bolt and have at it. This has the advantage, or disadvantage
(depending on how you look at it) as to allowing you to drill what
ever size hole you want as opposed to what is properly required.
You'll find these around machine shops.

Good morning Roger - problem with a v-block is that you still need to
insure the drill passes thru the center of the bolt; unless you know a
trick, the v-block will get me perpendicular to the shank, but does
nothing for centering the drill-bit (unless you know a secret???) - Mike
