    The red vertex is for drill presses and is pretty long, I have varying degree of success in using it on my knee mill. You will need to drop the speed to around 100rpm and use machine taps with a spiral flute. To get it to reveres you really need to yank the quill back.

    The soba looks interesting in that it has a double speed reverse.
