CNC machining center User:

Hey CNCmakers, I am shopping for the tooling we will be using with these new V8 CNC machining centers.  What size retention knob do they use?

CNCmakers Support:

V8 can use BT40 tool chuck, and in generally you need to prepare the

ER32 or ER25 collect.

CNC machining center user:

I understand the BT40 tool holder size.  What I'm looking for now is the retention knob, also known as "pull stud".  Attached is a picture of what I am looking for.

Thanks!

Have a great day!
