A land region 42 includes a front land portion 44, a left-side land portion 45, and a right-side land portion 46 which together define a periphery of a chip control pocket 40. The chip control pocket 40 includes a front descending wall 47 and a rear ascending wall 48, a left-side descending wall 50 and a right-side descending wall 52. Each of the walls of the chip control pocket preferably has a curvilinear configuration. A protuberance 54 is spaced between the left-side descending wall and the right-side descending wall, and has an elongate top surface 56 spaced along a protuberance axis 66 preferably perpendicular to the front cutting edge 60. The protuberance also has a left-side surface 67 and a right-side surface 68 each sloping downward toward a left-side descending wall and a right-side descending wall, respectively.
