The Kreg® Pocket-Hole Jig 320 makes it easier than ever to build wood projects — whether you’re building your first DIY project, or you’ve been working with wood for years. The Pocket-Hole Jig 320 works with materials of any thickness between 1/2 Inch and 1-1/2 Inch. It features two drill guides, a removable spacer, and stops for 1/2 Inch, 3/4 Inch, and 1-1/2 Inch-thick material that give the versatility you need to build with boards and plywood. The included material thickness gauge and easy-set drill bit make setup simple, while the convenient clamp adapter and anti-slip base hold the jig precisely in position while you drill perfectly positioned pocket holes every time. The jig and its included components store in a durable, compact case that even has space to store Kreg Pocket-Hole Screws — with 40 sample screws included.
