Some sort of sacrificial v-block? But the part still has to be held in it
somehow.

I do this periodically. I take a block of steel and drill a hole to
hold the piece and drill a hole for a guide to drill the cross hole.
If I am doing a bunch of them or want to do it nice I use a drill
bushing for the cross hole. I clamp the block of steel with whatever.
