A drag guide member for a torch nozzle is disclosed which will guide a burner tip during a metal cutting operation. The drag guide member of this invention is readily replaceable when worn through contact with the kerf. In one embodiment, a gun sight member having shoulders thereon adapted to ride on the edges of the kerf is threadedly received in the lower portion of the burner tip. In an alternative embodiment, a ring member adapted to be threadedly mounted on the circumference of the burner tip is provided. Said ring member mounts spaced gun sights about the circumference thereof so that when one gun sight is worn, the ring may be rotated to position a replacement member.
