A tool holder has a main body having a holder head extending away from a holder shank in a forward direction, a clamping member non-threadingly retained in the holder head, and a locking member operatively engaging a single abutment surface of the clamping member. The holder head has an insert receiving pocket at a forward end thereof with a pocket support surface substantially facing in an upward direction, and the clamping member is located entirely rearward of the pocket support surface with the abutment surface facing generally upwardly. The tool holder is configured to direct a clamping force towards, and clamp a cutting insert against, the pocket support surface.
