The Pocket-Hole Jig 520PRO is our most versatile jig yet. It's the essential jig for project builders who need an easy-to-use joinery solution wherever you work - in the backyard, on the driveway, or even in a friend's garage. The 520PRO is loaded with features, like the VersaGrip 360 degree-rotating handle that helps the jig adapt easily to nearly any pocket-hole project. VersaGrip features integrated clamping with pump action clamping - just squeeze the handle until your material is clamped securely. With this flexible design, you'll never have to worry about struggling with large boards or sheets to add pocket holes in the right places. Instead, the 520PRO works in almost any orientation, so you can easily reposition the jig, clamp it, and drill perfect pocket holes.
