Jig Settings
To create the strongest joint possible, you’ll need to set your jig to match the thickness of your workpiece. The
Kreg Jig® Jr. makes this easy, in just two simple steps!
For 3/4” material, place the step of the bit as far forward as it will go and tighten the depth collar at the 3/4” marking.
To get the right Pocket-Hole depth, you’ll first have to adjust the position of the Depth Collar on the Drill Bit. The collar prevents the your drill from plunging too far into the workpiece, so its position is essential.
Begin by placing the bit inside the Depth Setting Gauge found inside of the Kreg Jig® Jr.’s case. Place the step of the bit as far forward as it will go, then slide the Depth Collar onto the shank of the bit until it reaches the marking which matches your workpiece thickness, as shown. Lock the Depth Collar firmly into place with the included Allen Wrench.

Jig Settings
To ensure the exit-point of your screw is at the center of the workpiece for the strongest joint possible, you’ll also need to adjust the Positioning Sliders on either side of the Kreg Jig® Jr.
Positioning Sliders shown set for 3/4” thick material.
On the bottom of each Positioning Slider there are markings which represent different material thicknesses. Press
each slider with your thumb and slide it until the marking which matches the thickness of your workpieces comes into alignment with the large arrows on the bottom of the jig, as shown.

Clamping
With the Kreg Jig® Jr. properly set to match the thickness of your workpiece, you’re ready to clamp the jig in place and start drilling. Depending on the type of work you’re doing, you’ve got several options:
For the majority of applications any simple bar clamp or c-clamp
you have lying around will work 
just fine to keep the jig clamped 
tightly to the workpiece while you
drill your Pocket-Holes.
With the included Clamp Pad Adapter, the Kreg Jig® Jr. can be connected directly to any one of our Face Clamps when you need to take your work on the road or just get faster and more repeatable Pocket-Holes.
In certain tight situations where the use of a clamp is not possible, the Kreg Jig® Jr. can also be secured in place with a common wood screw driven through the Mounting Hole on the top of the jig.

Drilling |
Along with the Jig settings, another important part of getting the strongest possible Kreg Joint™ is to space your Pocket-Holes evenly across the workpiece. Your Kreg Jig® Jr. features a 2-hole Drill Guide which lets you drill holes in narrow stock without having to reposition the jig.
For panels we recommend placing the first Pocket-Hole roughly 2 inches away from the exposed edge of the panel, and every 6” after that.
Included with your Kreg Jig® Jr. is a stepped drill bit designed specifically for use with Kreg Joinery™. While the large part of the drill actually creates the “pocket”, the narrow tip drills the guide hole for the screw. When
you drill your first hole, place the bit about an inch inside of the Drill Guide, bring the drill up to full speed, and plunge the bit
smoothly and consistently into the workpiece.

Choosing a Screw
Fine Thread
Fine thread screws are recommended for hardwoods as they reduce the chance of the material splitting when driven.
Deep Square Drive improves driver engagement and reduces the possibility of cam-out.
Use in woods such as:
• Ash • Oak • Maple • Walnut • Hickory • Cherry • Mahogany • Birch
Coarse Thread
Due to a significantly larger thread diameter, coarse thread screws offer a much stronger hold in composite materials such as MDF and plywood.
Self-Tapping Auger point eliminates the need to drill a pilot hole.
Use in woods such as:
•Pine •Cedar •Basswood •Poplar•Plywood•Melamine•ParticleBoard
