A bit extender can be a real problem solver. Not only can you reach into spaces where you can’t fit a drill, it also lets you drill and drive close to a corner, or nearly parallel to a surface, without risk of damaging the work with the spinning chuck.

The quick-change chuck is sprung so the bit locks in place when inserted. To release it, slide the collar forward and the bit pops up, but remains lightly held by a rare-earth magnet. A floating sleeve on the shaft lets you hold the extender in use.

Not for use with impact tools. An excellent buy.
