Threading nipples to the spokes is the most time consuming part of building wheels. Thanks to the speed nipple bit you can now do it with the cordless screwdriver, save yourself some time and still have all the nipples threaded on the spokes to the same depth.
A protruding nub machined into the tip of the speed nipple bit keeps the nipple centered and prevents the tool from slipping off. Eventually, as the nipple is fully threaded down the spoke, the nub touches the approaching spoke and unseats the driver. This ensures that all the nipples are threaded on to the spokes to the same depth, leaving you at the perfect starting point to build great wheels.
Works with conventional slot-head nipples.
