These hex shank drill extensions accept any standard quick change hex shank bit. They're most commonly used with quick change spade bits to drill deep holes in wood and other materials.
Each extension features a recessed black sleeve to prevent accidental releases, and a slim tapered quick release chuck to help guide through holes as small as 11/16" in diameter.
Quick change extensions are available in 6" and 12" lengths. Please choose size under product options above.
