The invention provides a new pin-type toolholder for polygonally shaped indexable inserts, comprising a holder body (10) and an insert site from a bottom of which there projects a pin (15) upon which the insert (12) is located, and a wedge (17) for wedging engagement between a support surface (19) of the holder and an adjacent edge surface (20) of said insert. The forward projection of said wedge facing said insert comprises a first pair of distantly provided protrusions (24, 25) for abutment against a top face of the insert and a second pair of distantly provided protrusions (26a, 26b) for abutment against an adjacent edge surface (20) of said insert. <IMAGE> |
