Arbor for Boring Head 1-1/2" x 18, 1/2" straight shank

Description

I used this once on a boring head I modified to cut a taper in the lathe but the tool overhang was too much for what I was trying to do. It would probably work very well if used as intended. I've since abandoned cutting long tapers on the lathe. :)
