Dear All.,
I recall a posting some time back, that gave a contact e-mail or an address to a company that were capable and happy to do deep hole drilling / boring in steel bar.
As I remember the general concensus of the thread was to either "buy the hole" or to use EDM to make the hole.
I have looked for this thread in the forums – but for the life of me cannot find it.
Perhaps someone recalls it and coujld point me in the right direction.
Kindest regards Anna
