00452 Tight Fit® 3″ Threaded Shank Extension For Drill Bits and Tools

The Threaded Extension is three inches in length, excluding the external threads, for those deep hard-to-reach spots. Using it with the Chucking Spud and TightFit® threaded shank drill bits provides the utility of an expensive set of “deep reach” extension drill bits. Used with the Right Angle Drill Attachment, the Extension allows work over/under or around obstacles. It is made of mild carbon steel (1144) and has a body diameter of 3/8″ with 1/4-28 UNF-2B and 2A internal and external threads, 5/16″ wrench flats for easy removal after job is done and is black oxided to prevent corrosion while enhancing appearance.

Note: Must be used with TightFit® threaded shank drill bits or other threaded items.
