<p>A tool holder (100) includes an insert pocket (102) having a support surface (110) with a pocket recess (116) occupied by a lever pin (120), and a fastening member (130). A head portion (122) of the lever pin (120) has a lever head rear contact surface (C), located above the support surface (110), for pressing against a bore (148) of a cutting insert (140) in the insert pocket (102). The fastening member (130) engages a threaded recess (118) which extends from the pocket recess (116) along a threaded recess axis (T). The fastening member (130) includes a guiding prong (134), located within a blind hole (126) in the front of the lever pin (120). A clamping contact surface (B) of the fastening member (130) is adjacent to a lever front contact surface (H) of the lever pin (120). A first longitudinal distance (hi), between the lever rear contact surface (C) and the lever front contact surface (H), is smaller than a second longitudinal distance (h2), between the lever front contact surface (H) and a lever lower rear contact surface (G).</p> |
