Threaded Extensions are extremely versatile and provide the functional utility of several extension drill bit sets. Too often drill bits are too short or too long for specific jobs. The Extensions thread together to create any tool length necessary to get at a problem in a deep or narrow location. In addition to TightFit® threaded shank drill bits, the Extensions work with a variety of other threaded tools. They also work with the Right Angle Drill Attachment for getting around corners or over/under obstructions.
