ABSTRACT:
A toolholder for holding a cutting insert having an axial hole is disclosed having a pocket therein for seating of the insert and a hole in the toolholder extending transversely through the bottom of the pocket. A pin having a head for engaging the insert and a pivotal shoe member cooperate in the hole such that, as the rotatable pin is tightened, the shoe member forces the head of the pin to tilt toward a side wall of the pocket and clamp the insert to the toolholder.
