In this case use an Indexable Insert Drill and clean the bottom with a Special Ground Boring Bar. Also if the hole is extremely deep I suggest truing the outside and sending out for Gun Drilling. Gun Drilling can be done within .001 depth, diameter, and perpendicularity to the true face and outside diameter. Then you will have to make an Arbor to finish the rest of the work in the Lathe.
