Wholesale Tool currently is selling their import long tap wrench for only $9.95.
A long tap wrench is a handy thing for getting into recesses when retapping holes or when the engineer designs a part with less-than-rational access to all features. The import wrench is 13″ long and holds taps from 1/4″ to 1/2″. It’s both cheaper than getting a set of tap extensions and slightly more rigid, which is important when tapping. Of course, it’s usually preferable to use pulley taps as they clear smaller spaces better, but not everyone has them.
It’s worth noting that you can also hold drills, easy-outs and countersinks in a tap wrench, so this could also be used for deburring the back side of a hole or breaking off an easy out in a hard-to-reach place.
