A method for restoring a tool for fabricating a part from composite laminate material, comprising the steps of:

• drilling a hole with a drill bit through cured composite laminate material positioned overlying a surface of a wall of the tool and a contact surface of a contact member such that the drill bit contacts the contact surface of the contact member, wherein the contact member is positioned and moveable within a bore defined by a wall of the tool with at least a portion of the contact surface of the contact member aligned with the surface of the wall;
• and
• moving the contact member with the drill bit such that the at least a portion of the contact surface moves in a first direction within the bore and moves out of alignment with the surface of the wall.
