Pull studs make the connection between the spindle and the toolholder.

The two most popular styles are ISO and BT.  Because they have different dimensions it is almost impossible to mix them up.  For safety's sake, make sure you select the correct one.

 


Please make sure that the pull stud you order is the exact pull stud your machine uses.  Improper choice of a pull stud can cause damage to your machine spindle, the tool holder, and can cause a serious safety hazard
