Tree j325 tool holders

[MadPickinSkills]

Hello, does anyone know if j325's use bt40 or cat40 tool holders? Also do they use the pull studs?
Thanks

Either, but CT40 is easier to find the retention knobs. The retention knobs are a short squatted looking one. Think some Fadals used the same ones.

I have used a couple BT40 tool holders although CAT 40 is the standard. From what I have found the difference is the threads for the pull stud. In both cases you will need pull studs. The English version is PS475 and I'm not sure about the designation for the metric version but I think I got some from CTC Tools
