PRODUCT SPECIFIC SAFETY WARNINGS
> To avoid serious injury, keep hands and fingers away from the
spinning router bit. Maintain awareness of the bit at all times.
> USE ONLY IN A VARIABLE-SPEED TABLE-MOUNTED
ROUTER WITH A WORKING FENCE. NEVER USE IN
A HANDHELD ROUTING APPLICATION.
AVOID THIS SITUATION!
> NEVER FEED YOUR WORKPIECE
BETWEEN THE BIT AND THE
Fence

Direction
FENCE. Because of the direction
of the bit’s rotation, the bit could
“grab” the workpiece and propel it
away from the table at a high velocity,
potentially resulting in property
damage and serious injury to
anyone in its path.
> Additionally, when the bit grabs the
workpiece, your hands could be drawn
into the bit, resulting in serious injury.
> Turn off and unplug your router before
installing the bit or adjusting the
cutter height.
> To avoid bit slippage during use, make
sure to install the bit properly in the
router. Insert the bit in the collet until it
bottoms out; then back it out 1/16" to
1/8" and tighten the collet.
> Never use a router bit that is
damaged or dull.
> This router bit requires the use of a
fence with split faces. The bit must be
partly “buried” in the fence between
the halves of the split fence.
4
> ALWAYS use table featherboards to
make sure the workpiece stays tight to
to the fence as you move it past the bit.
Always use a push stick to advance the
workpiece through the cut.
> Never postion a featherboard so
that it applies pressure into the cutter.
Use featherboards only on infeed
and outfeed sides of the cutter.
> Recommended operating speed for this
router bit is 18,000 rpm. Do not exceed
the recommended speed.

Cut Stock to Size
When cutting your
stock, also cut extra pieces that can
be used to make test cuts for verifying
your setup.
1. Prepare the blanks for your Beadlock
tenons by cutting your stock into strips
3/8" thick x 13⁄8" wide. These dimensions
are critical, but the length is up to you;
just make sure you will be able to control
the workpiece as you shape it at the router
table. We recommend a length of at
least 12".
2. Make sure that the faces of your stock
are square to the edges. You will be running
the stock on edge past the bit, so it’s
important that the stock is square.

Bit Setup and Use
THESE WARNINGS PERTAIN TO ALL REMAINING STEPS:
> To avoid serious injury, keep hands and fingers away from the
spinning router bit. Maintain awareness of the bit at all times.
> USE ONLY IN A VARIABLE-SPEED TABLE-MOUNTED
ROUTER WITH A WORKING FENCE. NEVER USE IN
A HANDHELD ROUTING APPLICATION.

factory-milled Beadlock tenon stock
can be used as a guide to help make
setup quicker and easier.
5. Plug in and turn on the router. Use a push
stick to make test cuts to verify the bit
cutting height and fence position. Test
the piece in a mortise drilled with your
Beadlock jig to check the fit. Fig. 3.
1. Install the Beadlock Tenon Router Bit in
your table-mounted router.
2. Sight down the table and adjust the height
of the bit until the bottom curve intersects
with the plane of the table surface. (You
will fine-tune this position after making
test cuts.) Fig. 1.
3. Move the fence so that most of the bit
is “buried” behind the face of the fence,
with the deepest point of the flutes in the
bit lined up with the fence face. Fig. 2.
The goal is a depth of cut that just rounds
the face of your workpiece without making
it narrower overall.
Never postion a
featherboard so that it applies pressure
into the cutter. Use featherboards only
on infeed and outfeed sides of the cutter.
4. Install featherboards on the table on both
infeed and outfeed sides of the bit and set
it to maintain pressure on your workpiece
as you feed it past the bit. Fig. 3.
6. If fine-tuning is needed, turn off the router,
wait for it to fully stop and unplug it before
making adjustments.
7. Once adjustments are made, make an
additional test cut. Repeat the adjustment
and test-cut process until desired cutting
results are achieved.
8. Rout your workpiece(s) on both faces (front
and back) of your stock to create your
Beadlock tenon stock.
