I am looking into buying a moore version 2 jig borer off of ebay. Apparently the tooling for these is very expensive. So I can find the correct taper for boring bar tool holders for decently cheap. If I got say a half inch boring bar holder would that also be able to hold endmills or fly cutters? I.e. once you get the tool holder on the spindle the holder-to-tool connection is it just a cylinder with a setscrew and you can stick anything that fits in it? Also would I need a collet chuck?
