Dingle berry honing (or whatever it is called)

The OP may find this helpful: Untitled Document

And this: Engine Hone, Flex Hones, Cylinder Hones

The OP also needs to understand that the honing angle will vary with both the up and down speed AND the drill speed. I would recommend a slower speed like 500 RPM +/- so that you can move up and down more slowly and thus better control the angle. The video at the end of the 2nd link above can give you an idea of how fast to move up and down; what they show closely matches the 1 second top-to-bottom-to-top cycle time mentioned by RRR.
