This durable hardened steel drill bit is designed for exclusive use with the Kreg Deck Jig. It features a quick-change compatible shank and a uniquely designed stepped tip. This stepped design creates both the guide hole for the screw and the shoulder which secures the head of the screw in one plunge of the bit. The bit itself is built from high quality stainless steel and features aggressive fluting which clears material from the hole as its drilled.
