The Home Improver's Solution for Building with Wood What is a Kreg Jig? With the Kreg R3 Jr. Pocket Hole Jig, you can build bookcases, shelves, and storage projects for your home. It's also great for creating custom built-ins, and countless other home improvement projects. Plus, the Kreg Jig R3 can be used portably to make lasting repairs around your home. Clamp Pad Adapter The Kreg Jig R3 includes a Clamp Pad Adapter, which allows the R3 to be easily secured to your work piece using any standard bar clamp, C-clamp, or Kreg Face Clamp. For faster and more repeatable pocket holes, choose a Kreg Face Clamp. Material Thickness Setting Independent positioning sliders feature nine depth settings, allowing you to easily join materials from 1/2" to 1 1/2" thick in 1/8" increments. Dual Positioning Sliders Dual positioning sliders help you properly set your jig based on the thickness of the material you are working with. Simply depress the button on the side of the jig and move the sliders so your material thickness is aligned with the arrow on the jig body. Superior Angle Unlike competing jigs with a shallower angle of approach, the Kreg Jig Jr. features an optimized drilling angle specifically designed to increase driving efficiency and minimize the overall size of the pocket hole. Wood-Chip Relief The Kreg Jig R3 includes one wood-chip relief hole for every drill guide hole, designed to keep the drill bit clear of excess wood chips, minimizing drill-torque, increasing the longevity of your drill bits, and allowing you to complete a perfect pocket hole in just one plunge.
