This single-Piece stepped drill bit was designed exclusively for drilling concealed holes with the Kreg Deck Jig™. The bit creates an unobtrusive hole on the edge of your deck boards. The bit comes complete with a depth collar that controls the depth of your drill bit when drilling. The depth collar is secured in place on the bit with the included Allen wrench. This Deck Jig™ drill bit and the KTX driver bit that came with your Deck Jig™ are fully compatible with standard 1/4 in quick-change chucks.
