Park Tool Spoke Nipple Driver ND-1

The ND-1 is designed to drive conventional slotted nipples onto spokes quickly and easily, making it a great time-saver and an essential tool for wheel building. The hollow-ground centering tip keeps the tool perfectly aligned while driving in nipples, and automatically ejects when the nipple is sufficiently threaded onto the spoke. Built with a comfortable dual-density grip and lined with precision-made bronze bushings to ensure a long, smooth-running life.
