Add a second bit to your Kreg® 300-Series Pocket-Hole Jig, or update any Kreg Jig to make working with 1/2″, 3/4″, and 1 1/2″ materials even easier. The Kreg® Easy-Set Pocket-Hole Drill Bit with Step Collar and Gauge/Wrench is the same stepped bit that comes with 300-Series Kreg Pocket-Hole Jigs. This bit works with materials from 1⁄2″ to 1 1⁄2″ thick, and features engraved markings for 1/2″, 3/4″, 1 1/2″, along with the matching Easy-Set Stop Collar. The Material Thickness Gauge allows you to easily determine material thickness (1/2″, 3/4″, 1 1/2″) easily, too. A 1/4″ hex-shank fits all standard quick-change chucks. Compatible with all Kreg Pocket-Hole Jigs.
