Claim:
An apparatus for clamping an insert in a tool holder, comprising: a head portion including a first bore passing through a top surface and a bottom surface, and a second bore passing through a first side surface and a second side surface intersecting said first bore; a clamp pin including a clamp portion and a cam portion having a first angled surface and a second angled surface, a portion of the clamp pin being positioned within said first bore; and a lock screw movably mounted within said second bore and including a first angled surface and a second angled surface for engaging said first and second angled surfaces of said clamp pin, wherein rotation of said lock screw in a first direction causes said first angled surface of said lock screw to engage said first angled surface of said clamp pin and act as a first cam surface to move said clamp portion of said clamp pin in a direction downward and toward said insert, and wherein rotation of said lock screw in a second direction causes said second angled surface of said lock screw to engage said second angled surface of said clamp pin and act as a second cam surface to move said clamp portion of said clamp pin in a direction upward and away from said insert.
