Euro mill newbie - 40 taper questions

Long time lurker, soon to be new euro mill owner.

I got rid of my last round column import mill-drill and was close to buying a new square column import bench mill, when a friend offered me a small Maho MH400 P. I'll post more on that in a separate thread, but the goal is really to clean it up into a nice, compact manual mill.

I have a lot of R8 tooling and I wasn't planning to get this mill, and I haven't even wrapped my brain around the geometry of using a euro-style mill yet, but I will.

The mill has exactly one tool holder (pics attached), so I'm starting from scratch. The manual calls out ISO40 taper, but my searches seem to indicate that Cat40 with the correct retention knob / pull stud works. Is that true? Are there differences? Can I start collecting Cat40's (not NMTB's) off eBay or others and buying retention knobs to convert them?

Or is there more to it than that?

These pull studs from MariTool look close to the one I have. Nodicor has some for other listed Maho models, that are clearly different.

I have also seen what look to be more modern "ISO40" tool holders on eBay and elsewhere that have colored plastic ends on the retention knobs. Are those similar, but not compatible? Are those retention knobs removable and able to be replaced with M16 knobs? I haven't found a source for correct looking M16 knobs, but I suppose they are out there?

My goal is to keep the hydraulic closer, so I really want to sort out what I can or can't use with this machine.

Thanks for any help and hints,

--Jon
