An old tool setter showed me the following years ago.

Drop the holder in and partially tighten, tap holder down and in with
hammer to seat it properly then tighten fully. I find doing that it's
perfectly repeatable. Use a soft faced hammer :)

I always have one lying about on the lathe for tapping centres and
chucks in also.  

Andy - RS Stock No. 381-4701 is perfect for the task <G>.

All the tools I use work at 0 or 90 degrees to the lathe axis. Never
found the need to set them any other way.
