Parting and grooving tool with clamping arrangements

A parting and grooving tool comprising:

• a toolholder,
• wherein the toolholder includes a unitary toolholder main body portion having a shank at a first end and a clamping arrangement at a second end,
• wherein the clamping arrangement includes an elastic clamping arm interposed between a second arm and an insert-receiving pocket,
• wherein the insert-receiving pocket has a top surface formed by a portion of the clamping arm and a bottom surface formed by a portion of the main body portion for contacting a top and a bottom surface of the cutting insert, respectively,
• wherein the second arm is separated from the clamping arm by a slot, and a threaded hole extends from a top surface of the unitary toolholder main body portion through the second arm to the slot,
• wherein the threaded hole receives a screw to move the clamping arm into and out of contact with a top surface of an insert seated in the insert-receiving pocket,
• wherein an axis of the threaded hole is substantially perpendicular to a longitudinal axis of the insert-receiving pocket, and
• wherein the axis of the threaded hole intersects the insert-receiving pocket.
