Default What would you call this tool? Bolt drill guide?

Some years ago, I watched an A&P drill a shank so it would accept a
cotter pin.

Was a metal block into which various sized bolt could be screwn into,
each with a hole perpendicular to the shaft that would guide a drill
bit.

Anyone know what this might be called? - Mike

These are probably what you are looking for:

http://www.aircraft-tool.com/pdf/catalogs/ECat2006.pdf
page 75 shows three versions:
-Safety wire drill jig
-AERO SafTblock
-NUT SafTblock


http://www.ustool.com/catalog.pdf
page 96 shows some Drill Jigs similar to what you descibed.

I would call it a metal block threaded for various size bolts with
perpendicular drill bit guides...

I don't think it has a specific name other than bolt drilling tool or
bolt drilling block.

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

Place the v-block on the drill press, lower the drill bit until it
bottoms in the V, clamp the v-block down and every single cylindrical
object placed in the v-block will be drilled through the center.

I know the feeling. I have days when I make some rather elaborate set
ups on my vertical mill then have a eureka moment like that It's best
not to have a witness around at times like that.

Lay the bolt in the "V" with the threads over the desired hole. Clamp
the bolt in place using a block of wood to protect the threads. The
bolt should be centered in the "V" along with the drill hole.
Conversely place the bolt at the proper position in the "V", invert
the whole works and clamp it to a wood block. The crill should be
centered on the bolt and the block will protect what ever you would
have drilled without it...bench tops..etc:-))
