Settings
Step 1: Set the Drilling Depth
Slide the stop collar onto the drill bit. Insert the pilot tip of the
bit into the tip protector in the case tray, and snap the bit into
the depth-setting gauge so the stop collar rests in the recess
that has workpiece thickness marks along the edges. Push
the bit step tight against the tip protector and align the stop
collar with the mark that matches your workpiece thickness.
Tighten the stop collar set screw with the hex wrench included
with the jig.
To create strong joints, you’ll set the drilling depth, adjust the
jig position sliders, and select a screw length to match the
thickness of the workpiece. The Kreg Jig®R3 makes this easy,
in just three simple steps:
The example shows the stop collar positioned for a ¾" (19mm)-
thick workpiece.

Settings
Step 2: Adjust the Positioning Sliders
To adjust the jig so the screw exits at the center of the
workpiece, turn the jig over so the bottom faces up. Press
the ridged tab on each slider with your thumb and slide it
until the mark on the slider that matches the thickness of
your workpiece aligns with the arrow on the jig body.
The example shows the sliders positioned for a ¾" (19mm)-thick
workpiece.

Step 3: Select a Screw
Use this chart to select the correct screw length. Kreg offers a
complete line of pocket screws for every workpiece thickness
and type. All Kreg pocket screws are available at your Kreg

Choosing a Screw
Fine Thread
Because the smaller diameter
and thread pitch of our #7
ne-thread screws reduce the
chance of splitting the material,
we recommend them for hardwoods.
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 the large diameter
and thread pitch, our #8
coarse-thread screws offer a
strong hold in softwoods and
composite materials.
Self-Tapping
auger point
eliminates the
need to drill a
pilot hole.
Use in woods and composites such as:
• Pine • Cedar • Basswood • Poplar • Plywood • MDF• Particle Board

Clamping
To drill pocket holes
inside an existing or
already assembled
cabinet, remove the
sliders, ip them over
so the positioning
lugs will be on the
top of the jig, switch
each slider from one
side of the jig to the
other, and reinstall
them. Adjust the
sliders so the mark
on the slider that matches the thickness of the workpiece
aligns with the index mark on the jig body. (The thinnest
workpiece you can drill in this mode is ¾" [19mm].)
In situations where it is not possible to clamp the jig in place,
secure the jig to the workpiece by driving a wood screw
through the mounting hole. Remember to position the drill-bit
stop collar to match the thickness of your workpiece.
Position the jig with the
slider lugs hooked on the
edge of the workpiece.
A bar clamp or C-clamp
works just ne to secure
the jig to the workpiece.
With the included
clamp pad adapter,
the Kreg Jig®R3
can be connected
to any Kreg face
clamp for faster
positioning and
clamping.

Drilling
In addition to the proper Kreg Jig®settings, spacing pocket
holes evenly across the workpiece is an important part of
making a strong joint. The two-hole drill guide allows you to
drill holes in narrow workpieces (1½"-1⅞" [38mm-48mm])
without having to reposition the jig. For wider parts, drill
pocket holes 9⁄16" [14mm] from each edge add one or more
pocket holes between the edge holes so the distance
between holes does not exceed 6" [152mm]. For very large
parts such as panels, we recommend placing the rst pocket
hole 2" [51mm] from the panel edge and every 6" [152mm]
on center after that.
Before turning on the drill, slide the bit into the drill guide
until the tip of the bit touches the workpiece. Withdraw the
bit about ¼″ [6mm]. Turn on the drill, make sure it is running
at full speed, and feed the bit into the workpiece. Always
run variable-speed or multi-speed drills at the fastest speed.
While drilling the pocket hole, partially withdraw the bit
several times to clear the chips. Stop drilling when the stop
collar contacts the drill guide. Wait until the drill stops rotating
to withdraw the bit from the drill guide.
