The Pocket-Hole Jig 520Pro is the most versatile drilling jig yet. It is the essential jig for project builders who need an easy-to-use joinery solution wherever you work - in the garden, driveway or even a friend's garage. This jig sets the standard for pocket hole making versatility. It's packed with features like the 360° rotating VersaGrip handle that makes the 520Pro effortless to adapt to almost any pocket hole project. VersaGrip has an integrated pump-action clamp - simply squeeze the handle until your material is securely clamped. This flexible design means you no longer have to fuss with large plates or sheets to get pocket holes in the right places. Instead, the 520Pro works in almost any orientation, so you can simply move the jig into any position, clamp it in place and drill perfect pocket holes. Preparation for drilling pocket holes is simple. Preset material thicknesses on the drill guide block allow quick set-up for 1/2", 3/4" and 1 1/2" material. Plus, the adjustable fence provides repeatability when you need to drill multiple pocket holes in workpieces of similar thickness. A strong, steel-reinforced backbone and hardened steel drill guides ensure the 520Pro will provide years of quality performance when building projects.
