An adjustable fit laser-projecting tool used to project a light beam outward from the end of any cylindrical object for reference to the object's centerline axis or reference to points parallel to the centerline axis some distance away from the cylindrical object. The tool is comprised of a clamping means utilizing the outer surface of the cylindrical object as the contact surface. The tool contacts the outer surface of a cylindrical object as to orient the tool to the centerline of the cylindrical object. A laser diode module is mounted on a sliding centering scale, allowing the laser diode module to be moved to the centerline of the cylindrical object or another desired position parallel to the centerline axis of the cylindrical object.
