    Abstract: An apparatus is disclosed for releasably holding a toolholder shank having a lockable surface and a releasable surface utilizing an actuating bolt with an associated threaded actuating nut. When the actuating bolt is rotated in a locking direction, the actuating nut is drawn onto the bolt thereby clamping against the lockable surfaces of the toolholder shank. When the actuating bolt is rotated in the releasing direction, a releasing segment acts upon the toolholder thereby ejecting it from the tool support member.

  • Patent number: 7104171
    Abstract: A toolholder has a conventional square shank body with a pocket extending downwardly from the top surface of the body so that the cutting tip of an insert mounted within the pocket is positioned below the top surface of the square shank body. This permits the pocket to have a back wall through which coolant may be introduced and directed against the cutting insert. Typically, the cutting tip of a conventional square shank toolholder is aligned with the top surface of the toolholder. Additionally, a toolholder assembly is disclosed which includes a plurality of such toolholders.
