An indexable piercing tip mounts to a nose portion of one of the jaws of a heavy-duty demolition shears so as to enclose and protect top, bottom, front, and two opposing side surfaces of the nose portion during use of the shears. The piercing tip has a first operative position in which a first set of piercing and shearing edges of the piercing tip are presented for use. When the first set gets dull or worn, the piercing tip can be rotated/indexed 180 degrees so as to present a second set of piercing and shearing edges of the piercing tip for use.
