A method for manufacturing a sidewall support surface of an insert-receiving pocket with a compound radius includes the steps of: 1) tilting a cutting tool at a primary tilt angle with respect to a first plane (x-z); 2) tilting the cutting tool at a secondary tilt angle with respect to a second plane (y-z), the second plane different than the first plane; and 3) rotating the cutting tool about an axis (z-axis) perpendicular to a pocket floor of the insert-receiving pocket while maintaining the first and second tilt angles. A cutting tool including a toolholder with the insert-receiving pocket having a pocket floor and the sidewall support surface formed with a compound radius is also described.
