Locking
Rebates
In woodworking it’s easy to get into
a rut. But often there’s a reason. You
tend to stick with what works.
That’s why, when I have to
build drawers for a project, more
often than not I’ll return to the
trusted locking rebate joint for the
joinery. It makes a strong drawer
and I’ve always liked the way it
looks.
A dado blade on the table saw
has generally been my tool of
choice to cut this joint. But
recently I came across a new way
to make this joint — with a
drawer lock router bit. Its clever
design allows you to cut both
halves of the joint with a single bit.
And I found that it works well.
THE SETUP . The key to using one of
these bits is the setup. After you
have the bit installed in the router
table, the first step is to adjust it to
the right height. In order for the
joint to be a tight fit, this is impor-
tant. The cutting height of the bit is
given by the manufacturer (mine
was 10mm) and it will only work
right when it is set at this particular

height.
Once you’ve zeroed in on the
correct height, you won’t have to
change it. Both halves of the joint
can be cut using this same setting.
The trick is in how you hold the
different pieces as you rout the
joint.
FRONT AND BACK . First you want to
make the cut on your front and
back drawer pieces. These pieces
are routed flat as shown in Fig. 1.
Just set the fence to rout the ends
to a depth that matches the thick-
ness of the sides, as shown in Fig.
1a. You can prevent chipout with
a backer board.
THE SIDES . Now all you have to do
is rout a matching cut in the
drawer sides. But this is a little
different. Don’t change the height
of the bit but move the fence for-
ward so that only the “tongue” of
the bit will cut (Fig. 2a). Now
you’ll cut the sides with the pieces
standing on end.
Just hold the side tightly
against the fence and make a shal-
low pass (Fig. 2). Again, using a
backer board is a good idea. You’ll
want to sneak up on the depth of
the cut, testing the fit as you go.
When the side fits flush with the
end of the drawer front, you’re
joint is done. W
Lipped Drawers
Occasionally a design calls for a
drawer with a lipped front as shown
in the near photo at left. Kitchen cab-
inets and some furniture styles often
call for this treatment. And the drawer
lock bit will easily accommodate it.
It’s simply a matter of making a deeper
cut in the drawer front. A couple of
passes will be necessary.
